Ever since he established Kiddo Motors in 2010, Sergio Armet has held our attention with a steady stream of keen-looking builds. Customers have noticed too—so Sergio’s had to grow his team.
Last year, 24-year-old Christoffer Mårtensson—a product designer from Malmö, Sweden—hopped over to Barcelona to join the workshop. He’s now cut his teeth on this stripped down BMW R100 RS.
The BMW’s owner was after something “in a classic café style”—with a budget geared towards reliability rather than outright performance. “The idea was to keep the patina,” says Sergio, “but with a clean and minimalistic look.”
Sergio immediately set Christoffer to work on the frame. Rather than rebuilding just the rear, the team decided to redesign the entire frame from front to back. “We wanted a straight line from the engine through to the subframe,” says Sergio, “and wanted to eliminate the BMW’s characteristic engine incline.”
Once the frame was done, Kiddo modified the drive shaft to work with the revised geometry and reinforced the top yoke. They then added a hand-made leather seat and front fender to complete the bodywork.
To make sure the BMW runs for years to come, the engine was completely overhauled. Sergio also decided to bring the electrical system up to date: he’s installed a 14V alternator, a 14V voltage controller, power coils and a new CDI.
All of that’s hooked up to a brand new, simpler wiring harness, running off a Motogadget m-Unit and a Lithium-ion battery. (The battery’s mounted behind the gearbox in a custom-made casing.) Motogadget also supplied the Motoscope Tiny speedo (sunk into the headlight) and handlebar switches, and Kiddo have installed a keyless m-Lock system too.
The rearsets are from Tarozzi—fixed to a set of one-off brackets—and there are mounting points for passenger pegs. Up front are a pair of Tommaselli clip-ons. The headlight is from Kymco and the taillight is a LED Bates-style unit.
Other neat little touches include a Monza gas cap, Goodridge brake lines and blacked-out Norton style silencers. Avon Roadrider tires round off the package.
We can’t tear our eyes away from the BMW’s tank though—finished in bare metal with a dash of turquoise.
Note how the color of the fuel lines matches the tank—it’s just one of many thoughtful details that make this build simply magnifico.
