More power and torque for all types of R 100 (since 1981)
in the complete range of the numbers of revolutions.
Less exhaust fumes and lower fuel consumption. The forged pistons are about
130 g lighter than the originals. With a compression of 9,5:1, the power and
torque are extremely increased. For instance, the motor power of a R 100 GS
or R 100 R goes up to 67 hp. With improved power and torque curves, more
driving fun is guaranteed.
For a rebuilt you don't need any cylinder head work! Only the piston and the
cylinder are exchanged. The cylinders are covered with Nisic, the piston,
covered with molybdane.
The complete set for rebuilding is 2 cylinders, 2 pistons, 2 gudgeon pins, 4
lock rings, 6 piston rings. If your old components are still okay, we'll
take them in part-exchange.
