The Wiseco 743M06640 Dirt Bike Piston Standard is designed for motorcycle and off-road engine applications requiring a dependable replacement piston. Built by Wiseco, a recognized manufacturer of performance engine components, this standard piston supports consistent engine operation and reliable fitment when replacing an original-equipment piston of the same specification.
