From speaking to people, most people seem to be fairly reluctant to buy a bike with more than say... 50-70K k's on the clock, and definately rather reluctant to buy a bike with more than 100K k's on the clock. From what I can gather, most motorcycle engines will need a bit of a refresh by about then... Does this cost much? What's involved? A change of rings and the valve seats redone? Much more? Anyway, looking at ads etc, it looks like most of the bikes on the market have about 50K k's or less, what happens to bikes with more? That get used to commute etc? There aren't ever many on the market, do people just decide they're going to use it to commute and never sell them? Ride them to the ground? I'm half thinking of starting to commute by bike (I take the train at the moment, which funnily enough takes longer, and is more expensive than if I rode to work...), and with the distance I have to ride, I'll be putting just under 20K k's on the clock a year, and that's *just* going to work and back. With that in mind, if I were to buy another bike (thinking of replacing my XV250 with something a tad bigger - although on the other hand fuel economy won't be as good and would probably negate the benefits of riding instead of train'ing), should I be overly concerned about the number of k's on the bike?
