How many miles do you have on your bike? I'm curious because I thought I remembered reading from somewhere that bike engines are not like car engines and that they do not last as long. I'm reaching here but I think I remember something in the ball park of 30k miles. I have about 5k on it now after about 8 months of riding. I also ride a 05 kawi zx-6r. How long does a bike engine last with proper maintanence and not having to change out major parts?
