Bardahl Plasma LXR 10W50 - 1 Litre Premium Fully Synthetic Motorcycle Oil

When the track demands everything your engine has — sustained high revs, brutal heat cycles, relentless mechanical stress — the Bardahl Plasma LXR 10W50 is built to stay in control. Engineered around Bardahl's proprietary E-P4 Plasma technology, this fully synthetic 4-stroke motorcycle oil delivers race-ready protection across the full temperature range, from cold-start to the sustained thermal punishment of a trackday or mountain run.

Key Features

• E-P4 Plasma additive technology uses electrostatically activated esters to bond directly to metal surfaces, reducing friction and enabling high-revving performance with minimal wear
• JASO MA2 certified — fully compatible with wet clutch systems for crisp, slip-free gear changes on sport and superbike platforms
• API SP rated, the latest and most stringent specification for maximum engine protection against LSPI, deposits and oil degradation
• Outstanding high-temperature stability keeps viscosity consistent under sustained track use, summer touring and pass riding where other oils thin out
• Actively reduces oil ageing, carbon deposits and sludge build-up, keeping internals clean over the full service interval
• Effective from cold starts through to extreme operating temperatures — equally dependable in stop-and-go urban riding as on circuit

Track-Bred Technology on the Road

The 10W50 viscosity grade is the natural choice for high-performance 4-stroke engines that generate significant heat under load. The wide viscosity range ensures a protective film is present the moment the starter fires, while the heavier 50-weight base resists shear and thermal breakdown once the engine is working hard. Bardahl's E-P4 Plasma chemistry goes beyond conventional additives: by exploiting electrostatic attraction, the ester molecules coat bearing surfaces and cylinder walls at a molecular level, closing the gap where metal-to-metal contact would otherwise accelerate wear.

Versatility Across Riding Styles

Although the Plasma LXR 10W50 was conceived for extreme-duty use, its high viscosity index means the oil remains stable and protective across a much broader range of conditions. Riders who combine trackdays with long-distance touring, canyon carving or daily commuting will find it equally capable throughout. Older 4-stroke engines meeting API SP or JASO MA2 requirements are also compatible, making this a single-oil solution for mixed-fleet garages.

FAQ

Is it safe for wet clutches?

Yes. The JASO MA2 certification confirms full compatibility with wet clutch systems, ensuring clean, consistent gear changes without clutch slip.

Can I use it in summer or on hot passes?

Absolutely. The E-P4 technology provides exceptional thermal stability, keeping the oil in grade under sustained heat, high revs and demanding mountain routes.

Does it protect during short trips and stop-and-go riding?

Yes. The high viscosity index keeps the film stable at low speeds and during repeated cold starts, providing reliable protection regardless of ride length.

Is it suitable for track and racing use?

Definitively. The high-performance E-P4 base was specifically developed for extreme mechanical stress — it is an ideal choice for trackdays, circuit riding and competitive motorsport.

Will it work with older motorcycles?

Yes, provided the engine specifies API SP or JASO MA2 and the 10W50 viscosity grade is appropriate. Always cross-check your owner's manual before changing oil specification.
