o equip the BMW R 100 models (GS, R, RS, RT, CS) from 1981 with high quality components, the replacement kit offers everything that the lover of classic models appreciate.

In addition to two nikasil-coated cylinders, the kit includes forged pistons that are 110 grams lighter than the original, as well as high-quality piston ring sets and piston pins with the corresponding circlips. The set is completed by a comprehensive installation manual and a TÜV certificate.

Just like its little sister, the 1000cc also enjoys a tidy increase in power and torque across the entire power band after fitting the replacement kit. A powerful 67 hp can be called up after the procedure. In use, the kit shines with smooth running and – due to the lighter pistons – a not to be despised degree of spontaneity.
