‘79 BMW R100RS – The Bike Lab

Posted on May 5, 2015 by Andrew in Brat, Café Racer. 16 comments

Inspiration is a fickle thing. Fickle, and sometimes a little bit crazy. Take the case of this BMW R100RS from the late Seventies. It was made in a very different shape to what you see here but now, almost forty years later, it’s been reborn in a new form. A form that’s been inspired by the same company’s brand new RnineT. Which itself was inspired by bikes like this. Confused? Well don’t be, because if the end result is a ride like this you’ve just got to trust that whatever the path was to get here, it must have been the right one.


“We are a shop based in Barcelona,” says Victor. “We’ve been working for more than a year as The Bike Lab, but we have many years experience with other Spanish shops. Our ethos is simple; we care about the details and we always look for the perfect balance between aesthetics and functionality.”


The brief for the bike itself was simple. “We wanted to make an old bike handle like a new one, while maintaining that classic look.” Victor says that in your average Barcelonian street, you can see plenty of stock boxer BMWs, some customised ones and lots of brand new RnineTs. “We wanted to take the best of each of these genres and build a bike that any of these owners would love to have.”


“We made the custom sub-frame from scratch, along with a suede leather seat, new fenders, handlebars and footrests. We’ve changed almost everything except the tank and the engine.” There’s also a new electrical system with a Motogadget speedo, some simplified handlebar switches and a hidden ignition on the upper yoke. All the lights were replaced, with extra special attention given to the headlight – replete with a custom-made bracket – giving it the illusion of being suspended rather than bolted on.


The bike’s front forks comes from a Ducati Multistrada 1000, which were then polished and painted black. The brakes are gold series Brembo units from an Aprilia Mille, with custom-made aluminium disks with a competition master up top. Rear shocks are custom-made Hagons that slightly raise the BMW’s back to keep the overall line nice and horizontal.


“With almost every part being new, we decided to reinforce the classic look with the paint job. We painted pretty much every component with the lots of black and two really classic greys. The only relief is the yellow of the lamp and the brown of the seat.”


Liking to leave something unique in every custom they build, The boys went to town on the front fender. It’s completely handmade and features a single side mount made from aluminium. “It’s the part that really pops and it distinguishes this BMW from all the rest.”


It’s clear that this build has marked lots of new things in the shop’s evolution;  there’s new people, a new workshop and a new website. It also marks the beginning of the next stage in the company, and if this Bee Em is anything to go by, it’s going to be one hell of a stage.

    Best BMW in a while. I do Like that front fender… The whole bike looks stout and fun to ride.

  • whytaylorwhy

    Simple, clean. Looks like a lot of fun to just tear about town in. I don’t get the mirror placement- but if it works…

  • Wow, this bike is so completely perfect… made me be a first time commenter. I have seen a lot of builds that I like, but this one I just absolutely love.

  • Ass Ripper

    Nice I’d ride it like I stole it LMAO

  • Alasdair Sykes

    Absolutely beautiful… the lines of that seat are sublime. Out of interest, does that mirror show anything other than a detailed view of your left kneecap? Not trying to be overly critical – but would consider using something like that on my current build if it works, cos it looks great.

    • Victor Thebikelab

      As you said with this mirror you have a grat view of your knee, it’s there so the police doesn’t stop you, you can see something but isn’t comfortable, i’m shure with a bigger mirror and a bit far from the light it will work fine

      • Alasdair Sykes

        If that’s what it’s there for then it’s 100% functional I guess! Great build anyway mate 🙂

  • like the way you have hidden the battery but could you tell me where?

    • I suspect the battery is inside a box just under the pivot of the swing arm.

      • well spotted, thanks but now am bored

  • Mike o’donovan

    it’s all just getting so boring – another stripped down airhead yawn…. we need some new ideas people.

    • guvnor67

      maybe some1 out there has a butt-kickin Streetfighter worth submitting, maybe Z-900/1000 based or GS Thou? I like 99% of the stuff on Pipeburn but totally agree with where you,re at

  • Fred

    Wtf . I thought we did this bike over? Next please.

    • think we did the next one over

      • Fred

        Three days! And no new bike! Cat got your tongue boys? Fred.

  • I like the balance of custom and function.
