If you race, it's essential that you use motorcycle racing oil. Castrol's racing oils are liquid engineered to withstand the pressures inside performance engines.
What oil do you need if you race motorcycles? It’s absolutely essential to use specialist race oil. That’s because the demands of the racetrack – and a high performance engine – create pressures that even the best non-race oils can’t withstand.
So Castrol’s motorcycle racing oils are formulated to contain high performance friction reducers and anti-wear additives that provide the ultimate protection for race engines, yet without robbing them of power output. They are also liquid engineered to match the exact tolerances and surface finishes within your bike’s engine.
Castrol POWER1 is advanced, synthetic, premium quality engine oil designed for 4-stroke motorcycles.
