JE Pistons has just released a brand new line of lightweight, high performance forged piston kits for the Suzuki GSX1300R and GSX1340R Hayabusa. The new piston kits feature a new internally braced forged side relief (FSR) forging that is both lighter and stronger than a traditional "full round" equivalent and utilizes a smaller skirt area to help reduce friction and increase horsepower. Perfect for high RPM, normally aspirated applications, these off-the-shelf kits are available in bore sizes of 83mm-85mm and 13.5:1 and 14.5:1 compression ratios. All kits include premium wrist pins, wire locks and JE Pro Seal Piston Rings. Custom configurations are also available.
