The Wossner 8098DC piston kit is a +0.02 oversize forged piston designed for Suzuki RM125 models from 2004 to 2012. With a 54.02mm bore and 53.97mm piston diameter, this piston offers increased durability and efficient heat dissipation under the stresses of two-stroke operation. Its elliptical geometry allows for uniform bearing surface contact during thermal expansion, reducing localised stress and preventing piston deformation. This high-precision piston is manufactured in Germany to exacting performance standards.
