Your dirt bike’s engine is intricately designed, with every piece performing a specific job to keep the machine operating as intended. Any engine component which is no longer functioning correctly can mess up an entire day’s off-road adventure. As small and simple as engine bearings are, they’re just as essential to the overall setup as anything else.
When it’s time to replace your dirt bike engine bearings and seals, Rocky Mountain ATV/MC has everything you need to get your motorcycle back in order. We stock a variety of parts from the industry’s big names. Are you looking for the All Balls countershaft seal kit? Check. Or do you want the Hot Rods crankshaft main bearing and seal kit? Yep, we’ve got that too. Just enter your bike’s make, model and year to see exactly what we have available for your motorcycle. (If you’d rather stick to original parts, no sweat! We also carry OEM bearings. Just click the OEM button at the top of the page.)
So whether you’re replacing your crankshaft bearing or rebuilding the entire engine from the ground up, you can count of Rocky Mountain ATV/MC to provide all of the dirt bike parts you need.

The '05 KTM 250 EXCs are notorious for leaking at the counter shaft seal. This package comes with a factory size o-ring and a suggested o-ring. The suggested o-ring helps to create a better seal, making this kit last longer than the other ones.Read All Reviews

i do 10 hours of riding in a weekend, Engine was fresh and this thing shattered putting metal all through my rebuilt engine. Used this bearing to save 20$, now I am going to be another 10 hours fixing this right instead of just using quality bearings the first time. Please learn from my mistakes and don't buy hot rods products, almost everything I have purchased from them has prematurely broken, this has been my last straw and I will never purchase hot rods products again.Read All Reviews
