Very good used 2015 bike

mid 2023 bought a used 2015 red ax4, of reasonable wear by the caring 1st owner who says he barely used it over the years. The clock is stuck at almost 15kKm. Riding it anew really felt awkward for me, as I almost never got to ride a similar bike since d early 80s. But after a few km onwards I decided I like this bike, & even in d way it looks , having finally changed to fresh tyres. After change'g to new sprockets & chain, I didn't replace back both covers. It looks & feels bulky but still nimble enough for such a small engine. I'd reckon it averages @ 43km/ liter. It easily starts col or warm. still runs very quite....but Hard to find spare parts it seems.
