High-compression pistons for BMW R 1200 GS 2004/2009
High-compression piston kit, manufactured from selected lightweight alloys to ensure minimal thermal expansion and dimensional accuracy.
Installable without modifications to the original components, it improves engine response and optimizes overall performance.
Jetprime products are intended exclusively for sport use on closed circuits.
The high-compression piston kit is designed to ensure optimal performance, thanks to the use of selected materials and lightweight alloys that guarantee minimal thermal expansion and dimensional accuracy.
The pistons are engineered to be installed without any modification to the original components, while maintaining original noise levels.
The reduced piston weight improves engine response, while the increased compression ratio (12:1) optimizes low-rpm efficiency and ensures linear and consistent power delivery up to the rev limiter.
The kit is supplied complete with wrist pins, circlips, and piston rings, ready for installation.
Technical specifications:
