My bike is a 2014 model. I've been riding it since January 2016, at which point it had done about 5,000km (3,000 miles) so I think that any unusual jobs have fallen to me.
Thankfully, I've had a pretty good run.
My rear wheel bearings went at about 60,000km (37,000 miles). At some point after, and before 107,000km, my fork seals needed to be replaced. I can't be more precise as my servicing spreadsheet became corrupted.
Other than that it's just been the usual - tyres, chains, sprockets, a couple of headlight globes, filters and brake pads. I replace the oil with a semi-synthetic, on-schedule, and I have the valve clearances checked per the book, too (I've had a couple out of spec on occasion, but not so much as to be a concern).
It is using a little oil now, and I typically top it up mid-service cycle which sees me fill about half the sight-glass. However, performance seems fine and this oil loss is not significant.
The bike is now at 150,000km. It is ridden daily over longer distances, so the engine runs at temp.
