Specs At A Glance

Good To Know

Q: Does the cylinder need to be machined for a .020 piston? A: Yes, a .020 oversize piston requires the cylinder to be bored and honed to match its exact size, so have a machine shop measure and fit it before assembly.

Q: Is a service manual needed for this rebuild? A: A manual is strongly recommended, as torque specs and ring end gap measurements are critical to a reliable rebuild on the TRX300EX engine.

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