What are the differences between XTM, XTC and XT-S 4-stroke motorcycle oils?

Bardahl XTM motorcycle oil benefits from the Polar Plus formulation, well known at Bardahl since its origins and constantly improved since. Polar Plus polar molecules act as micro-magnets on the metal. This technology allows the lubricating film to remain anchored on the metal walls, even after months of engine inactivity.

In motorcycle oil, at Bardahl, this is the entry-level oil. But its anti-wear additives are already on average 8 times more efficient than comparable products on the market and the extreme pressure additives up to 5 times more resistant than the competition.

A notch above, we find the premium range, XTC, which provides two additional protective films compared to a traditional oil: the Polar Plus formulation is retained but it is combined with Fullerenes C60. Composed of 60 carbon atoms, the Fullerene C60 molecule behaves like a micro-ball bearing which, by interposing itself between the metal surfaces of the engine, creates an anti-friction protective layer, further preserving the mechanics from wear and corrosion.

In more technical terms, Fullerene C60 allows high shear resistance because this molecule greatly facilitates sliding between metal parts.

Finally, for non-competition motorcycles, whether intended for off-road or road use, Bardahl has developed the XT-S Performance range. It is intended for the most demanding users and high-power 4-stroke motorcycle engines. The best in performance additives (Polar Plus and reinforced C60) is combined here with the best in high-purity synthetic bases (PAO and Ester). In this way, resistance to mechanical shear stresses is maximum.

At the top of the impressive Bardahl motorcycle oil pyramid, we still find the XT-4 Racing range, exclusively reserved for competition motorcycles.
