Everything has begun removing everything superfluous on the bike, maintaining only what is strictly necessary to ensure that the vehicle maintains the approval to be able to circulate on the road. First, they removed the center stand and its mounts from the frame. This not only saved weight, but also gave the bike more ground clearance. Also, they decided to remove the stock rear framereplacing it with a customized titanium auxiliary one, with a weight saving of about 5 kg.
Another change concerned the exhaust system, which has been totally redesigned: Oldtimer has opted for an Akrapovic titanium system with a silencer from the brand of the same name dedicated to the sporty BMW S 1000 RR. This not only reduced weight, but also improved the GS’s performance.
The customizer decided to remove the air cleaner box and replace it with a pod filter. Not only did this change save around 2.5kg, it also allowed for better airflow and improved engine performance. To further reduce weight, Oldtimer replaced all steel hardware with new titanium hardware. This operation has allowed a considerable reduction in weight while maintaining faith in the original structure of the bike.
A very painstaking and lengthy job, but one that made it possible to save a total of around 40 kg compared to the standard R 1250 GS, creating a lighter and more compact bike, thus suitable for off-road use. The stylistic cue then came from HP2 Enduro on BMWa model no longer in the price list for several years.
At the end of the work, however, the owner of the GS, Rob De Deken,
he sadly passed away and the Oldtimer guys dedicated the build video, as well as the project itself, to their friend’s memory.
On the following page you will find the video documenting the work done.
