lifespan

I was just wondering how long do you guys keep your helmets? I had an Arai Quantum which I bought brand new back in 1995 and I think I paid $375 for it. After about 6 years, I had worn it down to the point where it was it didn't feel as snug as it did when it was brand new. My best friend...

Just trying to get an idea on this

I was just wondering if the radial tyre were lasting less than the bias type on a vmax. Any feedback guys ?

whats the average fork seal lifespan for a vmax or a normal bike. not something thats being stunted. Only bike i've ever done fork seals on had 30k miles and was almost 20 yrs old, is that typical?
