MOTORCYCLE OIL & FLUIDS

Motorcycle engine oil types fall into three categories: conventional, part synthetic and full synthetic. Getting it right matters, as the needs of a high performance motorcycle are very different to those of an American classic. That's why we make it easy to choose the right Castrol oil for your bike with our quick and easy Oil Selector.

Most modern motorcycles have a wet clutch, which means that when you've changed the engine oil, you've changed your gearbox oil too. However, if you have a shaft-drive bike, or a motorcycle with a traditional two-unit design, you need to make sure you're running the right specification of motorcycle gear oil.

Getting motorcycle brake fluid right is essential for every rider. Not only is every Castrol® brake fluid liquid engineered to prevent vapor lock failure, they also protect your entire brake system. Whether you need Dot 4 motorcycle brake fluid, or motorcycle racing brake fluid, we have all the options you need.

We recommend that complex motorcycle maintenance tasks such as changing brake fluid are carried out by trained mechanics. But if you have a centerstand, a level place to park and a few simple tools, motorcycle maintenance tasks like checking and changing oil should be achievable for most people, thanks to our simple guide.

Triumph recommends Castrol premium lubricants for its high performance motorcycles. Castrol is the Triumph factory fill oil brand in your bike when it rolls off the factory and showroom floor.
