| The usual stuff for all bikes of a certain age. You say it's battered, not so bad if that's cosmetic, but it could also indicate that the owner doesn't care a whole lot.
So...Tyre condition, wheel bearings, brake caliper, pad wear and disc condition, headstock bearings, swingarm bearings, fork seals, suspension damping & condition front and rear, oil change interval, battery condition, servicing and consumable bills etc...
Duke specific stuff is obviously when the cam belts were last changed, whether the bike has been stood or regularly ridden. If the bike has been regularly ridden then the belts should be OK if they are less than 12K miles or two years old - if it's been standing then the belts might need changing, best to give them a visual inspection and check tension if you can.
Shouldn't have rocker issues, since that particular bogey doesn't seem to affect two valvers much (not saying it's impossible mind) |
