Overview

The Red Line 80W Motorcycle Gear Oil with ShockProof is a synthetic gear oil designed for powersports transmissions. It features ShockProof technology with a microscopic solid medium to cushion gear teeth while maintaining lower drag, promoting consistent shifting and proper wet-clutch operation. This formulation is specifically suited for 65cc, 85cc, 125cc, and 250cc two-stroke motocross transmissions, as well as shifter kart gearboxes and CRF transmission cases.
