Restore your classic motorcycle engine with the EAZ Cylinder Block for Old Model Royal Enfield Bullet. Designed for compatible older Bullet engines, this cylinder barrel features a traditional finned construction that helps dissipate engine heat.
The cylinder block forms the bore in which the piston moves during engine operation. It is an important component when rebuilding an engine with a worn or damaged cylinder.
Before purchasing, verify the engine capacity, bore size, stud spacing, and compatibility with your existing engine. Different generations of Royal Enfield engines use different cylinder designs.
