Why Wiseco Forged Pistons?

Unlike cast pistons, Wiseco's forged pistons are manufactured from high-strength aluminum alloy, delivering superior toughness and durability under the extreme heat and stress of high-performance motorsport use. Each piston is developed using in-house dyno testing to optimize shape, coating, and component design for peak performance.

The Garage Buddy kit is engineered to meet or exceed OEM specifications and tolerances, making it an ideal choice for competitive motocross and off-road riders who demand a reliable, performance-ready rebuild at a practical price point. Made in the USA.
