Description

Athena, leader in producing motorcycle spare parts for over 40 years, unveils its new range of 4-stroke off-road cast pistons. Produced with cutting-edge CNC machining tools, which ensure dimensional tolerances of less than 0.01 mm, Athena pistons are made of a special high-performance aluminum alloy with high silicon content that guarantee the same reliability of the OE piston, while at the same time providing greater resistance and excellent performance. The perfectly smooth profile ensures a regular flow and the perfect flame propagation. Some pistons’ skirts are moreover treated with a molybdenum disulfide coating applied by screen printing which further reduce friction to enhance performance and durability. Athena engineers ensure advanced technical solutions and the highest quality standards equal to or better than those adopted in OE production, so as to guarantee performance and reliability.

Each piston, engineered in Italy by Athena R&D department, is tested on engine dynamometer benches under progressive stress load, and thereafter on track to validate its performance even in the most extreme conditions. The proven quality of Athena pistons is offered at an extremely affordable price.

This piston for Athena Big Bore cylinder is equipped with piston rings that guarantee less friction with the cylinder and therefore a higher performance.

Athena takes care of the development of the pistons down to the smallest detail: the rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to increase the retain and the durability. The rings perfectly adapt to the cylinder liner even at low tangential load.

Features

  • Two-stroke pistons are made from 4032 silicium
  • Four-stroke pistons are made from 2618 silicium - the same material used to produce Formula 1 pistons
  • Both include 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 .005mm
  • Forged piston tooling allows for the lightest available product
  • Kits include antiwear coated piston, rings, pin and circlips

Additional Information

Kits include aluminum cylinder with galvanic coating design with forged piston with molybdenum coating.

Parts was what it showed. Back riding again with no fear or worries with my quick fix and got a used hose that is working great for my 98 Vulcan classic 800
