Touratech R 1200 GS Rambler


Taking it to extremes


The Touratech R 1200 GS Rambler promises to be a super-lightweight 1200cc adventure bike with excellent enduro characteristics, high performance potential and fantastic suspension. Does a liquid-cooled boxer weighing less than 200 kilos that bounds nimbly over rough terrain sound like a dream? With the R 1200 GS Rambler, it’s a reality.

It began with the K 199 model which didn’t exceed 199 kilos in weight. The result is one of the lightest R 1200 GS conversions ever.

A modern interpretation of the BMW HP2, it’s a motorcycle that not only looks like a sporty bike, but also rides like one, showing just how closely the touring and off-road sports divisions at Touratech are interlinked.

Touratech developed the Rambler in co-ordination with BMW Motorrad, and built two prototypes that only differ in colour: one in the black-grey-yellow Touratech design, and the other in classic BMW Motorsport colours: white, blue and red. The design implementation was done with clay model construction and prototyping which were carried out at TT-3D in Murnau, while the technical components were developed and manufactured at Touratech in Niedereschach, Germany.

Rambler scenicTouratech’s developers combined the engine-gearbox unit from the R 1200 R Roadster model with the shaft drive from the GS, giving the Rambler a directly responsive, high-torque drive system with 125 PS. Based on the Roadster, the chassis on this model is fitted with a tele fork as standard.

The suspension has been tuned by Touratech Suspension and the use of modern materials and technologies, fairing sections made from super-lightweight aluminium tube in conjunction with carbon fibre, a titanium exhaust system, and a powerful but less heavy replacement lithium-ion battery has helped to bring the overall weight down.

Compared to the standard model, the Rambler has shed nearly 50 kilos, making it incredibly agile.

Once the motorcycle was stripped of its fairing and all unnecessary mounting brackets, the frame was reinforced for hard off-road use. The original fairing was ditched to make way for the custom airbox, with fairing made from carbon fibre reinforced plastic (CFRP), and adapted protection bars.

Behind this is a self-supporting, 16.2 litre aluminium tank, which also forms the subframe. Together with a separate plastic tank (1.8 litres) housing the fuel pump, the total tank capacity is 18 litres. The slim seat, developed in a new process by TT-3D, does not require a base plate.

Another unique feature on the Rambler is the front brake: a lightweight single-disc brake, as found on sports enduros, yet it has ABS. A CFRP engine guard panel protects the crankcase and sump when riding the Rambler to extremes over rough and rocky terrain.
