Product Description
79mm Cylinder Piston Gasket Top End Rebuild Kit 310cc For Honda CRF 250F 2019-2025Features:
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.
