Lightest Wheel Spacers: Yamaha WR400F Rear

When I couldn’t find the part on a single other website I found oemdirtbikeparts & let me tell you I was thoroughly impressed with how he had one in stock & was very easy to talk to regarding the condition of the used one vs the new. Excellent customer service 200% will be buying from Boston again.

I have a Husky 501 that I went all out on with brighter lights, KYB forks, and better wheels. took about 45 days, yet I’m beyond pleased with the Organization of this company!

Have a 02 yz250 I wanted to make my own. With the help of Boston we decided to do 24 yz450f swingarm axles rear brakes 18mm by 50mm kyb a kit rear shock with sss forks and Brembo brakes! Really happy and lost 10lbs with the help of their wheels. Looking to do ti bolts but I think its more than enough as is and I’m very happy compared to my ktm 150 2022 model. Thx for all the help with my endless question. Tip with work with this company… buy some items then ask as at first they blocked me for asking 10 questions then not buying anything which I know understand they get over a 100 emails a day and Boston was the only guy that truly could help me do this correctly and I am astounded with his knowledge and quickness of responses on all of these unique questions I had!

Stark Varg Yamaha WR400F Mods!

My new stark varg is a piece of art, we just added suspension coatings, tunning, and works Brembo brakes to start, waiting on the new A60 Rims and titanium bolt kit to complete this already amazing bike! after 40 year of motocross riding this bike is a game changer especially with adding a dual hand and foot rear brake set up! Thx team really an enjoyable experience

They weren’t kidding these are 70% lighter and feel great and im 6ft 2 so they’re plenty wide, about a 1/2 inch narrower than my stock set up yet i like this.

Took a while but well worth the wheels and fork combo

I like to ride a bike and then see how one can improve the design and with the help of Boston and His team, we have done such many times these past few years! Thx for keeping me sane!

Purchased a used fe501 because I wanted to build it from the ground up. Paid 9000 for a 2020 with 600 miles that had a slip on pipe. Talked to Boston and he said to sell off all the parts we weren’t going to use. After getting 3500 back for the parts I was in a street legal beast for 5500 then I dropped around 8000 in this bike… with about 50 hours of work its a 60+ whp do anything machine. Wheels, forks, throttle body, ECU, brakes, crazy bright lights and shed over 15 pounds from stock. Can outrun any street bike in an urban area and still enjoy a motocross ride at my local track. A great feeling of accomplishment is felt every time I take it out!

I wanted purple plastics for my husky yet no one made it so we did black plastics with dark matte purple which turned out excellent, very trick to have an all-black bike with matching plastics to the bolts they sell!

With a world that’s unknown the bike make me feel free to whatever comes my way for the last decade I’ve had this company help me with my modifications on my bikes and yes they take time to get me the part yet its done right every time!

After seeing the Stark Varg E-bike running Yamaha forks with Brembo brakes I wanted to see why so I tried this on my 23 yz450f with their works front brake kit. For $1000+ dollars I wasn’t sure it was worth it yet when I use my front brake 100+ times a moto it was highly noticeable when finger strength later in the 45-minute GP. I 100% recommend this company yet plan it out and be prepared to wait 4-6 weeks as it did which was worrying until I asked my friend who knows the owner from riding with him at the Glen Helen 24 hours!

First off 5+star rating from me. I ordered parts from them twice now and no problems at all the only thing that made me nervous was how long it takes to ship parts but dont be worried you will get it. They get the impossible parts you cant get else ware discontinued parts aswell no problem for them. Be patient and play nice. If it was not for them my bike would be a bucket of bolts scrape yard. Keep in mind their making the impossible possible and bust their ass doing so for you. Be thankful their here . I cant thank them enough oemdirtbike parts are the real deal. I could hug them for what they did for me

Had a dream to build a kx500 dune bike that could hit any jump I threw at it. We started out by sending the shock and their KYB fork upgrade kit to Graeme Brough with custom excel a60 rims to match. Brembo brakes were added as well yet more of a want than a need. the biggest upgrades from me were the custom bored 41mm PWK Keihin short body and KYB forks set up for the dunes. the bike is also 15 pounds lighter between all the work we did with the titanium parts and newer suspension and wheels etc. Already had a buddy offer $15,000 after I’d hammered this thing for a year so had to stop by and leave a proper review, as most times in life we forget to say thanks to the people that helped make our thoughts a reality.

I ordered a part Nov 7th, have yet to receive it nor receive a refund have made many attempts to contact oem about it and ask for a tracking number because i had never received one. communication would be nice since i paid 885.37 on one part

I really just bought these to upset the boys at the track yet it’s nice when they make fun of the purple hue, then I slide in some knowledge that they are pvd coated for 50% longer wear coefficient

Ordered shipped the next day and got it 3 days earlier than expected.

The 41 mm carb upgrade really transformed the DRZ400sm from a hopped up scooter to a real motorcycle. The bike started up within three or four revolutions. I was astonished. Warm weather in Florida no choke and it idled perfect. Exactly what I told them I wanted, is exactly what they gave. After months maybe a year of adjusting the jets on my motorcycles I’m happy to say they know exactly what they’re doing and I have no intention changing anything. After warming it up it took a good 30 to 45 seconds to dial in the carburetor and get the mixture and idle perfect. Everything I needed came with the shipment and they have a great video on YouTube that walks you through it. The video was unnecessary it was so easy. I watched it after the fact just to make sure I didn’t miss anything. Thank you for coming through better than advertised….. Cristian

Customizing my life is what I do and my supermoto build was no different they helped me with some tough to find product and showed me a few trick to really get this 501 to its happy place!

Back in the day when I was racing GNCC lightening the bike was the name of the game yet now at 52 It’s more like building what I only once dreamed of. This was a lot of money for some bolts yet I can tell the chassis is stiffer and makes the bike look like the rest of my KTM 500 that’s got way too much money into it. I consider this sport a drug and I must say this is one of the best ones out there! Thanks for all the help.

waiting on response from seller to correct the order.

Had a mix up on the size of my wheel I ordered. Its was corrected right away and got my wheel very quick and in great condition. Will do business in the future with these guys.

I am highly satisfied with the service I received from oemdirtbikeparts. The parts that I had ordered were on back order so they went ahead and sent me the whole assembly already put together. I was not expecting that and I was pleasantly surprised. Will definitely be doing more business with them!!

They have Rare parts👍

The swingarm was toast on my 02 cr125 from the old owner’s neglect. Now Honda hasn’t made this rear arm for over a decade and no one had a reasonable option. When I heard they helped Justin Barcia win supercross on the Factory Connection team with a longer swingarm I felt at peace having them solve my issue. Not only does it look better it’s a 1/2 pound lighter.

I initially had questions about the difference between 2 different master cylinders. I typed up a question and then received a phone call about an hour later and was given a thorough explanation of the difference along with some other tips. The parts showed up quickly and we’re just as described. Awesome experience.

i was looking for a swing arm for my cr250r everyone i found looked like they where road hard and put away wet came upon oemdirtbikeparts they had a new oem in the box. i could not beleave it i bought it in a heart beat. they have more new oem parts i will be buying more this company is the best when you text or leave a message they get back to you. it would be better to talk to somebody though

Quality and durability is amazing, I jumped down a set of stairs and have been hammering this new supermoto 501 for months at the local sumo track with not one spoke coming loose! Can’t say that for my last few bikes thanks for supplyin such a dialed product. Shipping was super slow yet I guess ya can’t rush art!

My 2020 DRZ 400S was parked curbside while I was at work. Some dumbass ran into it and damaged the front forks and caused various cosmetic damage. I was devastated. I love my bike and have thousands into perfomance upgrades. A quick search into my options turned up OEM Yamaha WR400F Parts. 1 quick email and I was promptly contacted by Boston to let me know what my options were. He quickly put together an upgraded package (DLC upside down front forks to replace the conventional forks as well as all the goodies to go with it). We agreed on a very fair price and within hours I had received tracking info. The parts arrived quickly and upon inspection I noticed a slight bit of leakage from one of the fork seals (nothing malicious here, just shit happens). I reached out to Boston and not only was he apologetic but also offered me several options including return with a full refund. I really like this set up so I took him up with his offer to send me parts to fix it and cover any labor costs. In addition he offered me a store credit to make up for any inconvenience. He is a stand up guy who obviously has a passion for motorcycles as well as his customers. I will be using his shop exclusively at this point. Thank you!

Completely satisfied. I ordered my part and it was filled the next day and delivered first class mail. I received my part a day early.

I had some trouble getting the carb linkage delivered. It was returned to sender twice and turns out it was my fault (old change of address). But I reached out to these guys and they helped me the whole time. Even during Christmas and on the weekends they were texting me and resending my parts. Got them delivered and installed tonight! My customer will be very happy he doesn’t have to buy a new carb just to get the linkage. Thanks to all of you guys at OEM I will definitely be using you guys again.

Great customer service. The only company that had the part I needed. Part arrived fast.

I love this steed yet the front brakes with all this power don’t add up once hot. Went to a larger master and this brembo caliper which is sick looking! Very satisfied even tho it took quite a while to ship…

cool too have a company like this around hope they can keep it 💯 and make more shitaki like this!

The carb i ordered came amazingly quick and everything was as described. The service and support i received was also excellent.

Love riding yet I’m not who I once was on a dirt bike. So now I like to feel the difference when I add parts to my ktm. This year I purchased multiple upgrades from OEM- brembo, KYB and custom rims to name a few, I’m not sure if my lap times are any better but boy is it a safer more precise ride! Thanks for answering all my questions and sharing knowledge that I didn’t even know existed!

The delivery was on time and the parts were correct.

I purchased a drz400 from the OEM dirtbike parts team and they helped me make it my own! At first the drz was a great first street bike yet with time I had more enjoyment off-road. So with the help of Boston we turned it into a dirt bike I could ride to the trails and still be able to commute to work! After 10,000 miles I’m really glad I picked this bike and had the support of this company to guide me with the upgrades to purchase.

Went from a stock carb on my Drz400 to a lectron thanks to some paid advertising YouTube influencer.. the carb worked but after riding my friends with a fcr39mm I couldn’t deal with bottom end power loss from the lectron carb. Wish I didn’t cut my tps wire so I could use the 2nd map plug in but still way better! Might buy a wiring harness and get my tps back to even better this reliable daily driver!

These guys are right “wheelies night and day better with this set up as well! “

Honest people. Quick shipping. Will recommend and buy all the parts I need from them. Thanks OEM

It’s easy to find parts for my bike with this “Browse By Bike” search thing. Thanks OEM.

Item Looks brand new

Had a few questions on a Sunday evening and they got back with me quickly. Good price and great service. Can’t beat it.

Fast shipping quality parts

Total dedication to customer support and getting exactly what you need ! Doing it right the first time !

Kyb forks are the way to go hence why there on gas gas bikes! “red ktms” thx OEM team

All of my needs were meet.

If your looking for parts, these guys know how to get it ! Even though I spent a whole day cleaning before the install, I’m satisfied at this point ! Great communication, and response times are excellent ! Thank you !

The delivery of my part was very quick seamless and they kept me in the loop every step of the way.

thanks for fixing my issues with the 02 suspension and setting us up with new forks shock!

Good price

Brake master cylinder came undamaged and fast.

had it to me next day in nor cal.

The first time I ordered parts, it was decently quick. This time was really quick, I ordered it on the 13th, they didn’t acknowledge it until the 16th but it showed up the next day! thanks for being open during this world pandemic now Riots! best wishes! sorry I don’t know how to change the 1 star to 5…

Very hard to find part for my 2006 rm250, OEM had it. Fast fast shipping!!!

Good people

Everything I need for my Ktm 560 smr thanks again you will be hearing from me again Thanks

This item arrived to me and is in great shape just like described in the add.

The caliper and pads were very clean and free of damage. There was slight rust on the pins and sliders about the amount you’d expect to see out of a used part. but those cleaned right up and it works great…

Roll on throttle wheelies now. Best modification yet to Suzuki DRZ400S. Followed the recommended advice of OEM Yamaha WR400F Parts and opened up the top and right side of air box for increased air flow. OEM Yamaha WR400F Parts also took care of a broken part from shipping with a quick replacement . Old carburetor would have never pulled wheelies

perfect. exactly what I needed.

Boston found me some parts that I could not find anywhere I looked for a week, for my bike last minute weekend overnighted them to me and I had them on the bike by noon. Awesome service awesome knowledge letting me know what other options that I had or some parts that I could use to get through the weekend ,super fast shipping nice and tight Packaging “virus free ” 🤦‍♂️ all in all a great experience I’d recommend 10 out of 10!!!! Definitely my new Parts hook up !

It’s nice to say I built my own bike not bought, thanks to this team for making it easy and stress-free! shipping was slow last week so I give 4 stars

Packed nicely

Super fast shipping

Great communication

the part I needed for my forks was taking too long to get so I ordered set from these guys. made it to my race weekend. wish they would have sent some stickers I didn’t get any in the package…

would write a detailed review but I’ve got racing todo! wow guys this is amazing.

had a lectron carb on my DRZ and it was good improvement over my stock carb but then I rode a bike with this carb.. now a $1000 later I can say im happy with this bike and its wheelie capabilities.

wow nice to have some power to get the front end light when moving over logs and going over whoops, I like the 40mm option they gave me and was worth the extra $100 for my type of slower woods riding.

So glad I found oemdirtbikeparts.com…..parts, service, support, everything about them is awesome. My RFS has never run better than now….thanks for a fantastic carb! First place I will contact anytime I need anything!

I just wanted to say that the carb I bought from you for my 04 WR 450 is perfect. I didn’t even touch the air screw. Starts perfect, just a quick choke, then idles so nice. Power is way up from my old carb, which I figured ran perfectly. No popping on decel, nice crisp response. Even the famous stuttering from the TPS is almost gone. This thing could almost give my old GS 750 a run for it’s money. Very happy customer.

Boston and his team know what they are talking about! I linked up with them and my bike has never run better!

Had nothing but great service with this company. Got new forks and a complete top end upgrade, bar mounts and all. Shipping was quick thank god for an upcoming Sand dunes trip. Even gave me a set of fork buddies with my purchase to keep the new ones tidy, and honestly can say they’;ve made a huge difference after a couple months in on the new forks. Had both used and new parts I ordered, OEM had everything I needed and was super helpful on call! Thanks!

Fitment was right works awesome tons of power super helpful when it came to the package I needed

This is the second time I have ordered from OEM dirtbikeparts. The parts I receive new or used have been spot on and the customer service is exceptional. I will only order from OEM when I need OEM parts!

Very happy with service and product..will be purchasing more from them in near future! Thanks again!

Very happy with the product. Lined everything up perfect! The people there answered my questions and gave good advice. Thank you.

20 year old part that still works!

it was what they said it was,good shape,fit like a tee,will buy from these guys again,with I need some oem pats again

Boston set me up with my rear shock. Really nice and helpful! Great suspension

rode my friends yz250 with just the front forks off a new yz and decided it worked well enough to fix my old dirt bike up. When i called they mentioned matching rear shock as well to complete the conversion. After comparing the two bikes, id say the rear shock does just as much if not more than the front forks (maybe conjoined its just a great setup) any how im stoked that my bike feelz like a 2017 yz250 without the 8000 price.

I didn’t want cheap parts I wanted genuine yamaha and thats what I got. thanks for the brake upgrade too!

yz250 is happy

Brake pedal in very good condition. Toe cleat not worn and no rust. Aluminum still had factory finish and not boot worn except far a fairly deep verticle scratch about 2 inches back from cleat. No wear in or on frame side of pivot mount. Very satisfied with for price.

Was given this 2000 xr650l as a gift so i kept it in the family even tho its not my style. The bike is underpowered the suspension cant keep up with the weight of the bike. Seen a video of this company wheeling it like a motocross bike so i called them and found out they all upgrade carbs for this model. order both and wow now its my grocery getter pretty cool what you can with it and have the reliability of an older xr honda.

A crf front end conversion was purchased by my colleague from this company and i was actually curious about doing a FCR carb kit with this bike. They custom built me a adaptor and kit for a direct fit. Bikes really coming around considering how slow it was stock. Power is instant thanks guys feels more like my xr650r now, which also has an fcr carburetor… might be addicted 🙂

I took the plunge and got a new fcr carb from these guys. Wow! Power wheelies in 1st-3rd! This carb really woke up my xr650l. So much more fun to ride now. Austin was a champ to work with. I called him about 3 different times and he gave me patience and respect as well as sharing my enthusiasm with the new performance. He was happy to answer my questions. I really appreciate their great customer service. This is the single greatest upgrade I’ve done to the XR. The only way to get more power would be to get into the engine and that will involve a lot of time, labor and money as well as compromise the dependability and longevity of the XR. I’m loving the new power and performance this new fcr 41 carb has given me. It’s stronger through the entire throttle range. It’s an investment but I have no regrets, just dirt eating grins and new adrenaline rushes! Let’s ride!!

i’ve done it all to my big red, bikes already fast. now its fast and starts quicker/more reliable. Cool Xr upgrade!

Parts were received within 10 days.

Bought 2 shifters as OEM parts and both were as advertised. Both fit and were in good condition, other than being greasy. That is understood though as they are 2nd hand parts.

Good oem product. Recieved this wheel exactly as advertised. These wheels come with a tire on them but don’t expect much from the tire. The tire is just a bonus and will vary. Good price.

First time every using this site. Was a little unsure about ordering until I talked with someone. I gave them call folks were super friendly. They described to me how they get their parts and answered all my questions. Received my parts on time and they were just as described to me. Couldn’t ask for anything better. Beats searching ebay, facebook pages etc…

wheel was as advertised and ready to bolt on and go. However these used wheels come with tires but don’t expect a tire in good condition. The tire is really just a bonus but will get you rolling for a few rides. Good price. Thanks again Boston for the great customer service.

I have my bling set for 1800$ from Excel. this is my spare for the dunes and my hands are happy to not change out a rear tire every time we his the sand.

Always quick shipping and friendly service.

Parts can not be beat in price or quality this is my third order and probably not the last .

feeling accomplished, simple and most likely the break a lot since they freaking plastic.. bought the mod they sell as well incase is happens again.

For what its worth, the pedal was 1/3 the cost of a new one, it was in good condition as advertised and arrived very quickly.

Good cond

very easy to use website and fast shipping,

Now on to the triple trees after receiving them and inspection everything looked to be in Good used conditions with no complaints, now lets go to the installation ?? 1) the bearings were so seized on heat was not our friend or on are side trying to knock them off had to pull out the die grinder !!!

2) once we installed new bearings and installed the new triple trees we noticed that there is a 1/4″ difference between the top 2 trees where the top bolt of your number plate screws in to the tree the new set is set back by a 1/4″ overall the Ending result my number plate got modified and is pulled back Very close to cables not leaving very much spacing and free play, made it to the track for race weekend and my son had NO issues with the performance.

I will order from these guys again

Good product, way less expensive than brand new. Reasonably fast shipping will use them again

ended up going with the new carb from this company. bikes defiantly running better than it ever did. not sure were they get this because it not a Yamaha part but defiantly works better than any wr250f carb’d bike I’ve ridden!

fixed what I needed it to fix
