Optimized Pistons for 2023+ KTM 450 Machines
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, optimizing power, handling and more. The story is no different for 2022.5 and 2023 models, which is why Wiseco has applied its latest in piston innovation. Developed through direct testing with KTM 450cc engines, these pistons feature:
- Fine-tuned performance and leading durability through revised forging and finished piston design
- Proven development through advanced engineering analysis and in-house dyno testing
- Optimized longevity and performance in varying track and off-road riding conditions
- Updated piston skirt shape and ovality with ArmorGlide skirt coating to improve operational stability and reduce frictional loss caused by cylinder wall contact, providing consistent ring seal and power and eliminating premature wear conditions
- Updated boxed and strutted design to maximize strength needed for 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
- Lateral gas ports aid in consistent ring seal, compression, and power
- Accumulator groove reduces pressure buildup below compression ring to greatly reduce the risk of ring flutter
- Double-broach pin oilers improve wrist pin and small-end lubrication for improved wear
Plus, each 2023 GASGAS, Husqvarna, and KTM piston kit comes standard with DLC coated wrist pin, premium rings & circlips.
This modern-age piston design for the 2023 KTM+ models shares many of the beneficial design elements Wiseco achieved through its re-development process of its KTM four-stroke pistons. Simulated stress testing, engineering analysis, engine dyno time, and multiple prototypes went into Wiseco achieving it’s most optimized KTM four-stroke piston yet. See more on this development below.
Available for late model GASGAS, Husqvarna, and KTM 450cc four-stroke models.
