Description
When you’re running a GP1200R at the limit, stock pistons become a reliability liability. The WSM Piston Kit delivers OEM-equivalent quality with engineered improvements—specifically the MOS2 coating that actively dissipates heat and reduces friction, translating to measurable power gains and extended engine life. If you’re serious about durability and performance, this is the upgrade that justifies its cost through reduced ring wear and consistent combustion chamber integrity.
