79mm Cylinder Piston Gasket Top End Rebuild Kit 310cc For Honda CRF 250F 2019-2025
Features: If your cylinder blows through, the compression is too low, or even a piston seizure has occurred, then this kit is exactly the right thing for you. Kit includes cylinder, piston, rings, pin, clips & top end gasket kit (you get exactly what is pictured). The cylinder is made of aluminum for good cooling with an internal cast iron jacket (unlike which has a nicasil treatment). Piston is anodized for superior heat resistance and longer lifespan. The gaskets use performance materials to increase durability and provide greater reliability. Includes all gaskets pictured to rebuild top end. Kit is for big bore size - 79 mm, 17mm steel piston pin. Compression Ratio 11 : 1. The compression is designed for use with the original cylinder head. When installing, the smaller bearing on the factory camshaft has to be removed and transferred to the new cam. This kit is excellent as a low-cost replacement for defects in the original cylinder.

So far so good. Stock location on my 1972 Honda CB750. Didn’t need any of the adaptors or extra parts. Screwed right on and feels solid. Clear vision behind me and the convected glass is really nice for the wider field of view. 10/10 Would buy again for sure.
I was on YouTube and saw a video about this product and instantly ordered it. Bought them for my Ktm 890 adventure r and took 5 minutes to install. They come with extra bolts to accommodate various different bikes. They did not cheap out. Very good quality , fast installation and took 3 days to arrive from Florida to western Canada.
