Frequently Asked Questions

Q: Are the main bearings included in this kit?
A: No, this kit includes the crankshaft assembly and connecting rod. Main bearings and engine seals must be purchased separately to complete your bottom-end rebuild.

Q: Is this a "Stroker" crankshaft or stock replacement?
A: This specific CBK0223 kit is an OE replacement crankshaft. It matches your bike's original stroke and compression specifications.

Expert Pro-Tip: When splitting the cases for a crank replacement, always inspect your transmission gears and shift forks for signs of wear. Since the engine is already apart, it is the most cost-effective time to replace high-wear internal items and ensure your transmission shifts as crisply as your new crank performs.
