Replacement Kit 1000cc 99mm
Plug & Play

We now offer a Replacement Kit for the BMW 2V Boxer R 100 models up to 1980.
Through modifications to the cylinder base, this Replacement Kit fits these BMW 2V Boxer R 100 models from 9/1976 with an engine housing bore of 99mm.

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

Just like its little sister, the 1000cc also enjoys a decent increase in power and torque across the entire power band after fitting the Replacement Kit. A strong, measured 67 hp can be called up after the intervention. In use, the kit shines with smooth running and - due to the optimized Kolbe - a not to be sneezed at degree of spontaneity.
