@Gnasher, what would cause wear like this? lack of oil changes or is it just that Yamaha dont have the best gear box's...?
Neither, in my opinion. This looks like either wheelie/clutch less change damage and/or too many drag starts and missed gears, possibly due to a poorly set and or worn clutch, which has been corrected (the clutch) before moving the bike on. Now whether Rad has been doing the above or it was done by the previous owner, only he'll know. But it's perfectly possible to get this sort of issue only for it to sit there for couple thousands miles before it lets go.

Well, I asked my mechanic the same question. He said he only saw this kind of damage on bikes that were raced. Brutal gear changes with high load and high RPM are no bueno for any gearbox. It wouldn't be a problem for racing bike- they are inspected/rebuilt on regular basis, but I don't think that previous owner was that thorough:/
When I bought the bike it came with a quickshifter (I disconnected it right away), removed passenger seat and pegs... Go figure. Anyway, what happened, happened, and now I have a bike that's (hopefully) good for next couple of seasons.
