Checking and changing the oil
A thin film of oil is all that prevents your motorcycle’s engine from grinding itself to death. Checking and changing it regularly is a must.
With a unified engine/gearbox, most modern four-stroke motorcycles use the same oil to lubricate a high-revving, high-temperature engine and the closely-meshed cogs and clutch of the transmission. It’s a tough job, so checking, topping up and replacing your oil on schedule should be a top priority.
Never let your engine run low on oil. Check it regularly and top up with the correct grade and type of oil.
Most modern bikes are designed to run on synthetic or semi-synthetic oil. They resist high temperatures and stress better than mineral oils but some older engines need mineral oil. The correct grade will be in the bike’s user manual or you can look it up online. Always use what’s specified or ask your local dealer for advice.
