Big Bore Stroker Kit

• Product Details

  Athena offers a wide range of cylinder kits for off-road bikes with diameters and portings completely re-designed as original spare parts and/or specific boost to be used on tracks. In particular, racing kits consist of lighter pistons with a flat head, special portings, an exhaust bridge, and a new cylinder head designed to increase the compression ratio and improve internal combustion. For specific bike models, Athena also supplies special long stroke Racing kits complete with crankshafts and reinforced connecting rods.

  • Specially designed, high-performance forged piston.
  • Made from 2618 silicium - the same material used to produce Formula 1 pistons.
  • Piston uses 3% copper in materials for better heat resistance.
  • All pistons are forged using a precision heat-treatment process that allows for production tolerances of just 0.005 mm.
  • Forged piston tooling allows for the lightest available product.
  • Piston is sold complete with rings, wrist pins and circlips.
  • All gaskets made from the highest quality materials.
  • Head gaskets feature rubber-coated spring steel construction.

  • The included cylinder / cylinder head in the Athena Big Bore Stroker kit is constructed out of aluminum with a galvanic coating to increase durability.
  • The cylinder water jets have been widened for a higher flow rate, keeping the cylinder cool.
  • Another great feature of the Athena Big Bore Stroker kit is that it bolts on with no machining needed, and includes easy-to-follow step-by-step installation instructions.
