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.
If interested, contact Wiseco at 1.800.321.1364 ext. 3105 (Al) and request part # 11565M06450. Pistons come complete with a pin, circlips, and rings.
