Hi AlexandarBel. The only thing that I have fixed, is the stator and regulator, nothing else. The engine has 60k on clocks and never had any fault (mechanical or electrical), also never crashed or droped from the stand (thank God). I love my bike, I m not pushing her all the time and services are on time. The bike has some mods like rear shock from a CBR1000R, free flow exhaust and K&N filter and now I put a set of daytona 675 cams.
