Piston kit ETZ 301 SPORT with Teflon Duells

The piston for the ETZ 301 engine is called SPORT because of the thin rings used with a hard chrome coating for less resistance in the cylinder.

The Teflon coating of the piston helps when the engine is first started, as it provides a sliding friction surface, reduces piston resistance and helps it settle better in the cylinder. It also reduces the risk of seizure in the cylinder.

Piston kit includes:

1x Teflon-coated piston

2x piston ring 1.5 mm with hard chrome coating

1x piston pin D18 x 66

2x piston pin retainer
