Hi Paul,
The best way to help your engine to last as long as possible is to treat it well. Use the best oil you can and warm the engine up under a light load before stressing it. 70-80 percent of engine wear happens when the engine is cold, especially on the cams. Good running in probably makes the most difference but this is often out of your control if the bike wasn't new...still applies to the clutch though...no wheelies to start with ;-) I've got 40,000mls from a high compression 4cyl CBR400 Honda that revs to 15000rpm regularly with no problems whatsoever. I use good synthetic oil, warm it up, and keep an eye on the valve clearances (no cam chain to worry about cos it has gear driven cams). Given that the overlanding bikes are much lower compression and altogether less stressed that sports bike engines, I think you should easily get 3 or 4 times that with care.
Hope the chairs are performing well ;-)
Andy.
