M.A.P. Cycle Billet Piston Kits

  • Hi-Silicone, low expansion, Hi-Strength 4032 aluminum alloy.  The ultimate for severe use in air cooled engines.
  • 100% CNC Machined, utilizing the latest “Solid Works” CAD design. This allows for consistent cross-section providing the most even heat distribution with the highest weight reduction (lightest commercially available piston kits for less vibration).
  • Lo-Dome "Tight Quench" design for efficient flame travel and combustion (9.5:1 compression ratio and higher)
  • Zero Deck design for max power while minimizing octane requirements (9.5:1 compression ratio and higher)
  • 2nd Ring-Land "Accumulator" groove to prevent unloading of the top ring from trapped blow-by.
  • Updated wrist pin oiling
    • 4 location pressure fed wrist pin oilers
    • Increases oil volume to pin
    • Dual clocked pin bore grooving holds and disperses the oil around the wrist pin
    • Minimizes heat buildup to prevent galling between the small end of the rod and the wrist pin
  • Race proven ring pack features:
    • Designed to remain perfectly round making for the best sealing, quickest seating rings available.
    • Modern sizing for the least amount of friction with the most amount of heat transfer for cooler running pistons (longer life).
      • 1.0mm Nitrided Stainless Steel Barrel-Face Top Ring
      • 1.2mm Ferrox Cast-Iron Napier 2nd
      • 2.8mm Nitrided Stainless Steel Rails with expander (3 piece design)
  • Tapered wrist pin (I.D.) for rigidity and weight reduction
  • “Micro Groove" piston skirt for high scuff resistance.
  • Race Type "SpiroLoc" clips for reliability - Won't come out
  • Latest piston cam design reduces noise, and increases life better than any other commercially available vintage Brit Bike piston kit.
