DescriptionThe whole story▼
Bardahl's Plasma LXR 15W50 is a 100% fully synthetic premium engine oil engineered for motorcycles that demand serious thermal resilience. Built on Bardahl's exclusive E-P4 Plasma technology — a proprietary blend of vegetable esters enhanced by electromagnetic activation — it delivers stable, friction-minimising lubrication under extreme heat and sustained high-rpm operation, drawing on decades of Bardahl motorsport chemistry heritage.
Key Features
- JASO MA2 certified for full wet-clutch compatibility — clean gear changes with no clutch slip across all covered models
- API SP rated to the latest engine protection standard, guarding modern high-output engines against wear, deposits and oxidation
- E-P4 Plasma additive package combines vegetable esters with electromagnetic activation for exceptional thermal stability and anti-wear performance
- Formulated for air/oil-cooled and high heat-load engines, making it the natural choice for summer touring, mountain passes and stop-and-go urban riding
- High viscosity index maintains a stable oil film at low speeds and cold starts as well as at track-day temperatures
- Suitable for modern and many older four-stroke engines meeting API SP or JASO MA2 specifications
Heritage and Formulation
Bardahl has built its reputation on additive science that originated in racing and trickled down to everyday riders. The Plasma LXR line represents the current pinnacle of that lineage. The 15W50 viscosity grade is deliberately chosen for machines that run hot by nature — air-cooled and oil-cooled V-twins, large-bore adventure engines, and high-performance inline fours that see both long motorway stints and spirited mountain riding. Where a lighter grade might shear under sustained load, the 15W50 maintains its film strength and keeps critical tolerances protected.
Performance on the Road and Track
The E-P4 Plasma technology addresses the two failure modes that matter most in a high-stress engine: friction-induced wear and oxidative breakdown from heat soak. By anchoring the ester molecules through electromagnetic activation, Bardahl claims a more tenacious boundary film than conventional ester formulations — one that clings to metal surfaces during cold starts, holds firm through extended track sessions and resists thinning when the engine sits in slow traffic on a hot day. The result is cleaner combustion chamber deposits, reduced internal friction and longer interval protection for engines used across a wide range of conditions.
Fitment and Compatibility

- KTM: RC 390
- All air/oil-cooled and liquid-cooled four-stroke motorcycles specifying API SP or JASO MA2
Frequently Asked Questions
Is it compatible with wet-clutch gearboxes? Yes. The JASO MA2 certification confirms full wet-clutch compatibility — expect consistent, slip-free gear changes throughout the service interval.
Can it be used in summer and high-ambient-temperature conditions? Absolutely. The E-P4 technology is specifically engineered for outstanding temperature stability, whether that means a track day, a high-altitude mountain pass or a slow urban commute on a hot afternoon.
Does it protect during short runs and stop-and-go traffic? Yes. The high viscosity index keeps the oil film stable at low road speeds and during repeated warm-up cycles, providing reliable protection even before the engine reaches full operating temperature.
Is it suitable for track use? Definitively. The E-P4 base was developed for extreme loading and is well suited to trackdays and performance road riding where sustained high rpm and elevated oil temperatures are the norm.
Does it work in older motorcycles? Yes — it is compatible with modern and many older four-stroke engines, provided their manufacturer specification calls for API SP or JASO MA2 grade oil.
