For fast acceleration on the road and track, safe braking is essential -
so the second front brake was an important part in the engineers'
specifications. The fully adjustable upside-down fork from WP Suspension
with diameter 50mm brings sufficient rigidity and provides a mounting
for the 2nd brake. The 4-piston calipers of the R 1100 S BoxerCup
Replica are fitted with adapters and grip the corresponding 320 mm
diameter brake discs. They are activated with a 17mm radial pump from
PHOENIX, which is matched by the 16mm radial clutch pump.
The rearward view is provided by mirrors with milled arms from AC
To balance the front wheel guide, the rear spring strut is replaced by a
fully adjustable WP Suspension spring strut with higher spring rate.
