A recent post asked what was the longest you'd kept a bike for. It reminded me of a friend who'd bought a Honda RS250 new in 1981 and sold it last year... so, a nice round 30 years of ownership (it still started after a couple of kicks too). On the other hand, he'd only put 12,000 miles on it in all that time!
Perhaps a better guide to how well we get on with a particular bike would be how much we've used it... rather than how long we've been prepared to store it. So, what's the greatest mileage you've added to a bike?
