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. We recommend you:
- check engine oil level every week or 500km
- at the same time, have a good look at its colour and run some off the dipstick between your fingers. If it’s black or the oil doesn’t feel silky smooth, replace it and the filter
- treat the manufacturer’s recommended oil change intervals as a maximum. You’ll do no harm, and potentially a lot of good, by changing more frequently.
