Telelever front-wheel suspension – all the
qualities of the previous system plus helpful
modifications.
Conceived and designed strictly for road use and superior
comfort, the Telelever comes with a fixed tube measuring 35 mm or
1.38´´ in diameter, as on the former model, since this
is the best solution for a motorcycle of this character. In
conjunction with the modified longitudinal arm of the R 1200 GS and
suitable geometric adjustment, the result is a supreme combination
offering a perfect balance of sporting and comfort-oriented spring
action.
Like on the R 1200 GS, this maintenance-free system is designed
to reduce brake dive to virtually zero, contributing, inter alia,
to greater stability when applying the brakes while leaning over at
an angle in bends.
Front-wheel spring travel is 120 mm or 4.72´´.
Rear-wheel guidance and suspension – the
Evo-Paralever and TDD spring strut.
The lightweight drive shaft featuring the BMW Motorrad Paralever
(Evo-Paralever) is hardly heavier than a conventional swinging arm
with a drive chain. And apart from the modifications required for
the wider tyres, this wheel guidance system has been carried over
completely from the R 1200 GS, where this new design has already
proven the significant progress it is able to offer: Despite lower
weight, the entire unit is even stiffer than on the former
model.
Placing the support bar for taking up forces on the rear wheel
drive housing above the swinging arm helps to provide extra ground
clearance, the 10 per cent reduction in weight versus the former
model reducing unsprung masses accordingly. The bottom line for the
rider is a smooth and sensitive response at all times plus load
change reactions reduced to a minimum.
The new design of the rear wheel drive also comes in a
particularly dynamic look thanks to the 50-millimetre (1.97-inch)
hole drilled through the axle tube in the housing. A further
advantage is the lifetime fluid filling, with no further need to
change the transmission fluid for the entire life of the
motorcycle. The rear central spring strut on the Paralever swinging
arm incorporates travel-dependent damper technology referred to as
TDD for short, ensuring a progressive increase in damper forces as
a function of spring travel. The suspension therefore responds
smoothly and comfortably to even the smallest bumps on the road, at
the same time offering generous reserves on bad roads and tracks
with grooves along the surface or a very uneven structure at the
top.
This spring strut system was featured for the first time in 2002
on the R 1150 GS Adventure, with spring travel at the rear
measuring 135 mm or 5.3´´.
As an option the new R 1200 RT will also be available with BMW
Motorrad’s ESA (Electronic Suspension Adjustment).
Introduced as a production feature for the first time worldwide
on the new K 1200 S, this system enables the rider to adjust the
spring base and damper rate – the latter even while riding
– conveniently at the touch of a button from the
handlebar.
Wheels and tyres – light-alloy cast wheels in new
five-spoke design.
The newly developed, extra-light cast aluminium wheels in almost
filigree five-spoke design combine the advantage of easy care with
superior strength and stiffness. The front wheel measures 3.5 x 17
inches, the rear wheel 5.5 x 17. Tyre dimensions are 120/70 ZR17 at
the front and 180/55 ZR17 at the rear.
Brakes – EVO brake system with partly integrated
ABS for safe and dependable deceleration.
The proven EVO brake system featuring BMW Motorrad Integral ABS
fitted as standard offers supreme safety under all conditions.
Maximum, easily controllable deceleration using just minimum brake
power gives the rider additional safety especially when applying
the brakes in an emergency. And to meet many customer requests, the
new R 1200 RT comes exclusively with the partly integral ABS
version for an even more active style of riding.
Diameter of the front brake discs is 320 millimetres or
12.6´´. To reduce unsprung masses and allow an even
higher standard of brake precision, the diameter of the rear brake
disc now measures 265 millimetres or 10.4´´, as opposed
to 276 millimetres or 10.9´´ on the former model.
Woven steel cladding on the brake hoses and brake callipers stiffer
than on the former model offer not only a slight decrease in
weight, but also a more precisely defined, consistently stable
brake pressure point.
