MOTUL TRANSOIL 10W30 - 1 Litre

Motul Transoil 10W30 is a mineral-based transmission oil made for the gearboxes of two-stroke motorcycles. It is formulated for gearboxes running a wet clutch, where the oil has to lubricate the gears while still allowing the clutch plates to grip and release cleanly.

It suits dirt bikes and off-road two-strokes from small-capacity learner machines through to full-size motocross and enduro bikes, and is a straightforward choice for routine gearbox oil changes between rides or race meetings. Supplied in a 1 litre bottle.

Always check your owner's manual for the oil specification and capacity your machine requires before filling.

• Specifically designed for two-stroke engine gearboxes with a wet clutch

• 1 x 1 litre bottle of Motul Transoil 10W30

Confirm your machine's required gearbox oil specification and fill capacity in the owner's manual before use — do not rely on bottle size alone.
Use in the gearbox/transmission of two-stroke engines only; this is not a two-stroke pre-mix or injector oil and is not intended for the fuel or oil-injection system.
Drain with the engine at normal operating temperature and the bike upright and level, so old oil and suspended debris flow out fully.
Inspect or renew the drain plug sealing washer at each change and tighten fittings to the manufacturer's specification to avoid leaks or thread damage.
Refill to the level shown by the sight glass or dipstick, then recheck after a short warm-up with the bike level.
Avoid mixing with oils containing friction modifiers, and keep oil off the clutch plates during assembly work, as this can affect wet clutch engagement.
Change the oil at the intervals in your service schedule, and more often after racing, deep water crossings or any sign of water contamination (milky or discoloured oil).
Store the bottle sealed and upright in a cool, dry place out of direct sunlight, and keep the cap on to prevent moisture and dirt ingress.
Wash off skin contact with soap and water; take used oil and empty containers to a council oil recycling facility rather than putting them in general waste or drains.
