Valvoline 4-Stroke Motorcycle Full Synthetic 10W-40 Motor Oil 1 Quart
Valvoline's full synthetic 10W-40 matches Aprilia's recommended viscosity for the RSV4 Factory, making it a straightforward choice for the 999cc V4 engine that runs hot under hard use. The full synthetic formulation handles the tight tolerances and high rev range without breaking down prematurely. It's also wet-clutch compatible, so you won't get slippage issues. Caveat: one quart isn't enough for a full change — the RSV4 requires roughly 3.5 liters, so order accordingly.
