WÖSSNER Forged Piston – Manufacturer Ref. 8665DA
High-quality forged piston manufactured in Germany by Wössner, designed for demanding engine builders. Engineered to replace an original piston with standard compression, it fits both 2-stroke and 4-stroke configurations for Quad, Cross, and Roadster applications.

• Material: forged aluminium
• Bore diameter: 97.00 mm
• Piston diameter: Ø 96.960 mm (Ø 96.96 mm)
• Oversize letter: A
• Anti-friction treatment of the skirt
• Supplied with ring(s), circlips, and pin
• Compression: standard

The forging process gives the piston a homogeneous grain structure, valued for its mechanical strength. The anti-friction treatment of the skirt reduces cylinder/skirt friction and facilitates the running-in process, while the oversize indicated by the letter A specifies the dimensional machining for fitting to the bore.

Referenced on several off-road and supermoto models, it is particularly compatible with 450 cc machines such as:

• KTM 450 SX-F (2012)
• KTM 450 SMR (2012)
• KTM 450 SX-F FACTORY EDITION MAX NAGL (2010)

Product delivered complete (piston, ring(s), pin, and circlips) ready to be installed during a bottom-end overhaul or maintenance operation. Please follow the manufacturer's recommendations for installation and running-in.
