Purpose and Specifications

MOTUL TRANSOIL 10W30 1L is a premium mineral gearbox oil designed for motorcycles, karts, ATVs, and quads with separate wet clutch systems. Its 10W30 viscosity flows smoothly at cold starts down to -32°C for quick protection, while staying strong up to 231°C to shield gears from extreme racing heat. API GL4 rated, it cuts wear on heavily loaded gears and bearings, ensures precise shifts, and prevents clutch slip for reliable power transfer. This 1-liter bottle substitutes for SAE 80 gearbox oil, keeping clutch plates clean and transmission efficient during intense rides.

When to Use / Replace?

Use in high-performance 2-stroke or 4-stroke engines like shifter karts, motocross, enduro, or high-torque transmissions needing wet clutch compatibility. Ideal for road, off-road, and racing where gearbox oil stays separate from engine oil. Replace every 3000-6000 km or 6-12 months based on manufacturer guidelines and your riding style - more often for track days or dusty conditions to maintain peak protection. Shelf life is 3-5 years unopened in cool, dry storage.
