21000 miles, bike thrashed almost every ride. oil changed every 4500, only issue was a bad front exhaust sensor around 16000 miles. new belts and valve service at 18000mls.
had to replace the cheap stock chain and sprockets at 10k it was stretched and tight links even though it was lubricated every couple of hundred miles. new chain holding up way better. new clutch cable fitted.
Did the clutch mod not long ago. (much improved feel)
Heated grips failed and have replaced one and repaired the other.
doesn't use any oil between servicing, great fun on the track especially in the wet, the traction control works great.
5 years old now and still love riding it.
