hi guys. do you know about PRO X piston. is it any good. what is the best one by you. thanks
@dtr-mkd 'Mitaka' is your better option for a standard engine. A higher silicone content than a Yamaha OEM piston too, makes them robust.
I thought they were PROX pistons. But maybe it is Pro x. I always use Wossner but have used Mitaka without issues.
