What is the life of a motorcycle engine?

Question

I'm wondering what engine size has to do with it, and type of engine. tell in miles please, I don't want to people to say this one lasts a medium amount of time, and this other one lasts a really long time.

like a vtwin, or a stright three cylinder.

And what do you think about the V4 that aprilia is supposedly gonna use in a new bike.

Answer 1

The answer above is correct. There are too many variables. Maintenance is huge, but touring bikes can easily take 2, 3, or 4 times as many miles as sport bikes.

So where does that leave us?  Maybe 30 to 50 K miles for a sports bike and 90 to 200 K for a touring bike. And then everything in between. On the other hand, I've heard of sport bikes with 70K miles and I've heard of touring bikes go bad at 40 K.

Back to square one....

Answer 2
