Product details

Motorex Power Synt 4T 10W-50 is a fully synthetic four-stroke engine oil developed for demanding use in hypersport and high-performance motorcycles. It is formulated for engines that share their oil with the gearbox and a wet multi-plate clutch, so it has to protect three very different jobs at once — and hold up when the engine is worked hard.

The blend targets aggressive power delivery alongside wear protection across the full operating range, from cold starts through to sustained high-rpm running. It carries JASO MA approval, which is the specification to look for when a bike runs a wet clutch, along with API SM, SL, SJ, SH and SG service categories.

Motorex is a Swiss lubricant specialist with a long history in motorcycle engine and driveline products, and is used widely by race teams. Supplied in a 4 litre bottle, which suits most single oil-and-filter changes. Always check your owner's handbook for the viscosity and specification your bike requires.

Prices are not live and may have changed since the last point shown.
