Wiseco has a limited amount of R5 350 Yamaha pistons available.  These forged pistons are +0.5mm over stock (64.50mm) size and have modern, permanently bonded skirt coating for years of trouble free performance. Wiseco does not stock this part; these are custom order pistons designed especially for the older piston-port R5.
