Motorcycle Drivetrain Bearings & Seals
Drivetrain bearings and seals are the parts you don't think about until they fail. A dry countershaft seal leaks oil onto your chain. A worn output shaft bearing causes whining and metal in the oil. Replacing these wear parts during a clutch or chain service prevents bigger repairs later. Rogue Powersports stocks complete bearing and seal kits for engines, transmissions, and final drives.
Bearing and Seal Categories
- Engine and Transmission Bearing Kits: All Balls and Pivot Works complete bearing kits matched to your bike's full crankcase and gearbox. The right call during any major rebuild.
- Countershaft and Output Seals: The seal behind your front sprocket fails most often. Replacement during a chain swap is cheap insurance against an oil-soaked drive.
- Crankshaft and Main Bearings: Hot Rods and ProX main bearings for two-stroke and four-stroke crank rebuilds. Critical to getting a long life out of a fresh top end.
- Clutch and Primary Bearings: Throw-out bearings, clutch hub bearings, and primary chain tensioner bearings that wear from constant rotation under load.
- Final Drive and Driveshaft Seals: For shaft-drive cruisers and BMW boxers, replacement pinion and drive seals stop the slow leaks that ruin a final drive over time.

Frequently Asked Questions
How long do drivetrain bearings last?
Output shaft bearings, transmission bearings, and clutch bearings typically last 50,000-80,000 miles. Replace at any major engine work; preventive replacement is good practice for older bikes.
Can I replace drivetrain bearings myself?
Yes with bearing pullers, drivers, and a service manual. Some bearings need a hydraulic press. If you've never done it, consider paying a shop ($150-400 typical). Wrong-direction installation causes catastrophic failure.
Are aftermarket drivetrain bearings reliable?
All Balls Racing, Pivot Works, and ProX bearings are widely used and well-regarded. Match the bearing size, type (sealed vs. open), and quantity to OEM exactly. Quality matches OEM in most cases.
Why are my drivetrain bearings noisy?
Common causes: worn races, contaminated grease, water ingress past failed seals, or excessive preload. Replace immediately — failed bearings can lead to transmission destruction. Don't try to ride past noisy bearings.
Do I need to replace seals with bearings?
Always — when removing bearings, the seals must come out and be replaced. Reused seals leak and contaminate new bearings. Seal kits are typically included with bearing kits.
