Description

Piston Kit – 56.00 mm – Yamaha YZ125
– Forged from high-silicon aluminum alloy for maximum strength and dependability
– Wiseco offers a complete range of popular piston models and years for both trail and racing applications
– Durability, longevity and increased horsepower
– Innovative forging design and piston skirt provide maximum horsepower and torque
– Features forged pistons, rings, wrist pins, and circlips
– These high-tech piston designs offer maximum compression ratios, ultra-stiff strutted forgings, and titanium nitride-coated rings, which all add up to more power that is sustained longer
– Each piston is E-Coated on the crown, ring grooves, and pin bore, for maximum wear resistance and protection from micro-welding, galling, and detonation
– GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression
– Additionally, boost ports are removed for a more predictable powerband and increased pull on the top end
– Cylinder sleeves must be purchased separately.
– Service intervals may be increased with Racer’s Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.
