Cylinder Works 18-24 85 SX/85 SX BW/22-24 MC 85 1714/21-24 MC 85 1916 Standard Bore Cylinder Kit

If you're rebuilding the top end of your 85 SX, 85 SX BW, MC 85 1714, or MC 85 1916, this standard bore cylinder kit from Cylinder Works is a solid option to get your engine running like new again. This kit is designed to bring back lost horsepower and performance, offering a way to restore your bike's power without going the full OEM route.

Inside this kit, you'll find a cast aluminum cylinder from Cylinder Works, built to OEM specifications. What really sets this cylinder apart is its Nickel Silicon Carbide (NSC) electroplate bore. This advanced plating allows for very tight tolerances, which means less friction as the piston moves up and down. That lower friction translates to better efficiency and helps make the bore extremely durable over time. The bore is also precision diamond honed to exact dimensions, ensuring the piston rings seal properly against the cylinder wall. This precise surface finish is crucial for good ring seal and helps retain oil where it needs to be, contributing to longevity and consistent performance.

This kit comes complete with a Vertex piston and all the necessary gaskets to get your engine back together. It's a comprehensive package aimed at making the rebuild process as straightforward as possible, giving you the parts needed to restore your bike's performance.
