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

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 Dirt Bike 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.

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

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 Dirt Bike Parts and opened up the top and right side of air box for increased air flow. OEM Dirt Bike 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
