• Wiseco pistons are world class manufacturers of hi-performance, after-market forged pistons for the motorcycle, ATV, personal watercraft, automotive and outboard marine markets.
• Their light weight in comparison to cast pistons enable higher revs with superior strength and optimal design.
• Wiseco pistons are made from forged aluminium produced in-house.
• The pistons come standard with patented ArmorGlide® coating material for reduced friction and noise with maximum power.
• They operate at cooler temperatures due to lower heat retention and can withstand higher loads and compression ratios due to the density of the forged material.
• Computer designed with precision skirt profiles to further reduce friction.
• The piston's wrist pin holes are reamed for optimal fit.
