All of this models can be outfitted with sidecars. An adapter frame, screwed
to the right side of the motorbike, makes it possible. In most cases a
4-point-connection is used. The adapter frame is made of welded steel
pipes and is connected with adjustable clamps (to avoid applied tensions)
to the motorbike frame. The adapter frame has two upper socket-joints
and two lower flat bolts. The clamps and screws are zincked, the frame
is black powder laminated and is outfitted with a registry number. The
adapter frame, once mounted can remain on the motorbike when the sidecar
is not in use.Security Information
+ Each adapter frame is TÜV (german state technical inspection) certified.
This inspection certificate is available.
+ Generally casted rims are not accepted for use with sidecars by the
german TÜV and therefore we do not recommend them.
+ Installation time: approx. 1 2 hours.
+ This BMW models are not recommended for sidecar use:
BMW /5: frames are less stable (reinforcement of the steering heading
is possible through alteration in a professional workshop).
BMW R 45: no shorter transmission available.
+ The original tele-front forks are more susceptible to wear. It is recommended
using a sleeve to give more tension to the front springs.
+ A front wheel swinging arm adds stabilty and is widely available. It
generally costs 1.000 1.500 € .
Hydraulic steering dampers are recommended for use on both suspension
systems to avoid shimmying.
+ The back wheel suspension can be reinforced by stronger springs. For
later GS-models a sleeve is adaquate for extra support. Early G/S, with
short swinging arm, should be equipped with a high quality spring
(ex. Wilbers, White Power,...).
