Dirt Bike Engine Complete Assembly Cases Crank Cylinder Genuine

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

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.
