My spark plug needed replacing at 16k km.Pretty good just following the maintenance best I can. My brake pads are about half way worn but i'll probably replace them soon (I don't chance my brakes) When the valves were checked at 16,000 they were in spec but the mechanic did say they might need adjustment at 32,000.
I had to replace the oil filter gasket and the edit*rubber valve cover gasket (after my road trip) was leaking a tiny bit but some sealant solved that issue. Keep in my mind I've put my bike through the ringer with a good mix of interstate, dirt, and mountain road riding.
The spark plug also looked really good at 16k.
I replaced the front brake pads at 18k km and rear at 24k km.
And added Pirelli Sport Demon tyres at 18k km.
The difference with the change of pads was amazing, night and day.
