Wossner Yamaha ultra-high performance forged piston kits are developed for both the professional racer seeking strength and reliability and the everyday trail rider who is looking for increased longevity over a cast-type piston that is fit to the Yamaha engine from new. Using technology that's been thoroughly tested and comes directly from the pinnacle of motorsport, F1, Wossner pistons are created from true hot forgings, with bridge box bottom design and skirt coatings. The result is the optimised shape for minimum weight, with increased strength and durability and less friction.

  • Piston Kit includes piston, rings, pin and circlips
  • Compression 12.5:1
  • Made in Germany
  • Wossner forged piston run much the same piston to bore clearance as genuine cast pistons - Piston noise is low even at old start-up.
  • Forged from 4032 (T6) high tensile strength aluminium
  • Wossner piston and rings can be used in all plated cylinders and cylinders fitted with a sleeve.
  • Coated skirt for anti-friction, also aids bed-in
  • Anti-detonation bands - Minimises crevice volume reducing the effects of unburned fuel between the piston and the bore
  • Accumulator groove - Aids compression ring sealing under high cylinder pressures
  • Precisely placed oil drain back holes
  • Highly machine-finished crown reduces carbon build up and aids stress relief, minimising the effect of hot spots causing detonation
  • Image is generic and may differ slightly to part supplied.
