Optimised pistons for Husqvarna, GasGas and KTM 450
Available for late model GasGas, Husqvarna and KTM 450 cc four-stroke models, American specialist Wiseco says that these are its "best KTM 350 and 450 four-stroke piston kits yet - a new-age forged piston design for new-age GasGas, Husqvarna and KTM 450 models.
"As one of the front runners in motocross and off-road dirt bikes over recent years, the KTM Group has routinely cranked out technological and performance advancements, optimising power, handling and more. The story is no different for its 2022 and 2023 models, which is why Wiseco has applied its latest piston innovations to develop these new kits through direct testing with KTM 450 cc engines.
"We have created fine-tuned performance and leading durability through revised forging and finished piston design with proven development through advanced engineering analysis and in-house dyno testing as well as optimised longevity and performance in varying track and off-road riding conditions".
An updated boxed and strutted design maximises the strength needed for the high-performance nature of KTM and Husqvarna engines without compromising lightweight characteristics. Internal window milling for added weight savings aids in quick revving without sacrificing strength, while lateral gas ports aid in consistent ring seal, compression and power.
An accumulator groove reduces pressure build-up below the compression ring to greatly reduce the risk of 'ring flutter'. Double-broach pin oilers improve wrist pin and small-end lubrication for improved wear. Each 2023 GasGas, Husqvarna and KTM piston kit comes standard with DLC coated wrist pin, premium rings and circlips.
"This modern-age piston design for the 2023 KTM+ models shares many of the beneficial design elements we achieved through the redevelopment process of our KTM four-stroke pistons. Simulated stress testing, engineering analysis, engine dyno time and multiple prototypes went into achieving our most optimised KTM four-stroke piston yet".
Wiseco products are available to dealers in Europe through selected distributors, including Parts Europe, Hoco Parts, Bihr, Duell and InnTeck in Italy.
