When to change oil on a dirt bike or motorcycle
Changing oil on a motorcycle is simple, but sometimes it is too simple that people forget to change it, and then they wonder why their bike just seized.
If you’re on a street bike, and you use it often, I would recommend changing it every few months, just so that the oil doesn’t get dirty and start damaging internal engine parts.
Off-road bikes, or dirt bikes, are probably the easiest. All you have to do is check the oil level and color every time you ride. If it starts getting low then you should probably change it soon. If the color is gray, that means it is getting dirty and a oil change should be done in the near future. If the oil is black, then you definitely want to change it because it is old and probably getting dirty. If you don’t ride everyday, then I would suggest changing your off-road dirt bike oil two to three times a year.
Motocross dirt bikes require a little more maintenance for pretty much everything. Regular oil changes are key, especially if you are racing. If you haven’t changed the oil in a while and you go race, then there’s a slight chance that you will lock up the motor, and that is not what you want to happen during a moto. I suggest changing the oil on a motocross bike every 3-5 races. Possibly more if you’re riding a lot in between race days.
Good luck, and don’t let that bike run out of oil!!
