Description
Elf Off Road 4 Racer 10W-50 is a fully synthetic oil from the Off Road range for four-stroke motorcycles in off-road competition. Here high revs, dust and hard shifting load the engine, clutch and gearbox all at once.
The oil is rated API SP and JASO MA2; no motorcycle manufacturer approvals are listed. Its frictional properties are tuned to transfer power through the wet clutch, an extreme-pressure additive protects the gear teeth, and the oil is compatible with DLC-coated and ceramic-composite parts.
Typical figures: 17.7 mm²/s at 100 °C, viscosity index 164, pour point -36 °C. Available in 1 and 4 litre packs.
Application
Four-stroke motorcycles for off-road competition, where high revs, dust and hard shifting load the engine, clutch and gearbox.
Worth knowing
Elf’s data sheet ties gear tooth protection to a separate anti-scuffing additive (Extreme Pressure) and explicitly mentions cavitation and tooth damage under pressure in the gearbox. The JASO MA2 class cannot confirm this: the T 903 standard tests friction properties for the clutch, and even the 2023 edition, which the oil exceeds according to its data sheet, has no separate gear pitting test. Gearbox protection here remains Elf’s claim, not a requirement of the class; a separate article covers what the JASO T 903:2023 edition changed and which test it still lacks.
Elf Moto 4 Racer 10W-50 has the same table figure for figure, with a density of 853 kg/m³ and a flash point of 250 °C, together with API SP and JASO MA2. The third Elf oil of this viscosity in the catalogue, Moto 4 Tech 10W-50, is recorded with the same figures but with API SN, so for a motorcycle that needs API SP, only the two Racer oils match on stated class.
