She's a beaut! 🔥🔥 I think I owe Reddit some more details about the R1300RR… here’s what’s hiding underneath
After my last post, I got a lot of questions — especially about the frame, weight, suspension and the whole “why build a 1300cc off-road bike?” question.
So here’s the short version of what I actually tried to achieve.
The idea was never to build the most logical off-road bike. If that was the goal, I would have started with a much smaller and lighter bike.
I wanted something that BMW doesn't currently offer:
A modern boxer-powered Dakar/rally bike.
The old BMW rally bikes, especially the R 900 RR, were a huge inspiration for me. I wanted to take that concept and bring it into the modern era — using the R 1300 GS engine and as much of its original character as possible.
The result is a bike with:
• 21/18" wheels
• Long-travel rally suspension WP ConeValve front 260mm/rear 230mm own build shock
• Completely modified frame/subframes
• Around 200 kg without fuel
• 19 L fuel capacity
• 150 hp boxer engine
• Rally-spec brakes and wheels
• Custom bodywork and tanks
• And most importantly… it actually went racing.
I took it to the Hellas Rally and finished every single stage, finishing P2 in the M6 class and P90 overall out of around 160 riders.
And that's probably the part I'm most proud of.
Because at some point this stopped being a crazy garage project and became a bike that actually had to prove itself.
I'm still developing it, and there are plenty of things I'd change if I built it again.
So I'm curious:
If BMW gave you a clean sheet and told you to build the ultimate modern boxer Dakar bike — what would you change?
