I put on about 8,000km-10,000kms per season...I usually ride about 8 months out of the year. I put on alittle more last season, because I uninsured my car during the summer months.
My last bike (1993 ZX-6E) had about 38,000kms on it when I sold it. Now a friend has it, and it stays in my garage, so I still see it all the time. This bike has always been well taken care of...oil changes every 3,000kms (synthetic), fluids and tyres are always checked and filled, chain is always lubed, valves adjusted and carbs synced at proper intervals, always washed/cleaned/waxed, etc. This bike has not missed a beat, despite it's somewhat high kms. You'll probably see it at some BCSB rides, Sewman's bike. Take a ook at it, you'd think it was a '98 6E with no more than 10,000kms on the clock.
