Good To Know

Q: What does .020 over bore mean? A: It means the piston is 0.020 inches larger than standard to compensate for cylinder wear, allowing a fresh bore to restore proper clearance.

Q: Will these fit my 1985 Yamaha Enticer 340? A: Yes, the 60.5mm piston kits are designed for 1978-1988 Enticer 340 models, but always confirm your engine serial number for compatibility.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
