From the watch case to the test track, Richard Mille does it all.
Exploring new ventures outside its watchmaking facility and into an entirely new world, Richard Mille proves why it stands out as an innovative mastermind with its first-ever motorcycle collaboration. First teased just four short months ago, the renowned Swiss watchmaker announced its newest partnership with Brough Superior and its plans to bridge together hand-crafted motorcycles and haute horology.

After 18 months of back-and-forth between Mille and Brough CEO Thierry Henriette, the two brands arrived at the RMB01. This purpose-built, track-focused motorcycle takes its design inspiration from early board track racers of the 1910s. Slimline bodywork, a minimalist seat, exposed mechanicals, and a fixed dropper-style riding position. While that vintage charm sets the tone, the rest of the build is more like a mechanical masterpiece, borrowing heavily from Richard Mille’s watchmaking world, like divided rims mirroring gear trains, titanium components machined for weight savings, and cases that mimic tourbillons.

The engine is a 997cc V-twin that’s less about unnecessary horsepower and more about usable power for weekends at the track. Built from solid aluminum blocks, the engine goes through a weight-saving process, with just 50 lbs of parts remaining from an original 352 lbs. With 130 horsepower at its disposal and aero-focused add-ons that increase downforce, RMB01 is designed for fast laps with a strong mechanical feel. The carbon chassis, which doubles as a structural exoskeleton, connects components in a way that’s more familiar to watchmaking than typical motorcycle design. There’s a stripped-down quality to the motorcycle that ties into Richard Mille’s obsession with revealing form and function.

The RMB01 will arrive at the end of 2025 in three finishes: Nocturnal Sapphire, Selene, and Pearl of Speed. Each one takes a different approach to contrast and color but avoids the flashiness you might expect from a project like this. It’s entirely hand-built in France, with only 150 chassis being made, each individually numbered. For those who’ve been following Mille’s watch releases or Brough’s revival over the past decade, the RMB01 feels like an evolution for both brands.
In an era of endless collabs and design gimmicks, this one actually feels thoughtful. It’s not trying to be a collector’s item, but it just might become one.
