Performance & Practical Benefits

What stands out about this oil isn’t just its specification sheet — it’s how it makes a bike feel on the road. Acceleration becomes smoother, shifting feels more deliberate, and the whole engine takes on a more controlled tone, especially at higher revs. The full synthetic base holds up when temperatures rise, keeping viscosity steady so the engine doesn’t feel loose or strained.

This oil is built to handle long periods of non-use too, which is a reality for many riders. Whether your bike sits for a week or a season, the corrosion inhibitors work quietly in the background, keeping internal parts from developing that dry, gritty feel. The wet-clutch compatibility is another big piece of the puzzle — you’ll notice the clutch engaging cleanly without the slip that inferior oils sometimes cause. It’s protection you can feel every time you roll on the throttle or downshift into a turn.

Why Buy OEM

That expertise shows through in this motorcycle oil. You’re choosing an oil that’s been tested under extreme conditions, refined for consistent performance, and trusted by riders who care about long-term engine health. It’s a practical choice — one that protects your investment and keeps the ride enjoyable mile after mile.
