I know, a bit of a theoretical question, but...I have a 98 VFR, close to 30,000 miles on her, I put on 2500-3000 per year. I do the suggested/regular maintenance, and properly store over the winter. I'm fairly certain the engine has many more miles in it, probably more concerned with the overall age. I'm really not sure what the limiting factor is with my current bike, or how many years/miles I can realistically expect to get. I love my bike, but am considering purchasing a new (2008/2009) model due to some of the deals being offered, knowing I'll have to replace my bike at some point, and the Gen 5/6 is the model I want to stay with. Any comments from riders with higher mileage/older bikes , or stats/info that anyone has seen?
