The Bott XR-1 takes the muscular core of a Buell and strips the surrounding motorcycle back to a compact, sharply defined street tracker. Its white tank, exposed V-twin and black structural sections create a deliberately simple silhouette, while the custom steel spine chassis gives the Spanish-built machine an identity separate from its donor.
A Buell heart in a new chassis
Bottpower’s reported figures place the XR-1 at 100 bhp and 374 lb, numbers that suit its lean, purposeful layout. The source describes the motorcycle as using a Buell engine, wheels, brakes and suspension within the custom frame. Rather than disguising those components, the design makes them part of the visual argument: the engine sits prominently beneath the tank, and the swingarm and rear wheel remain largely unobstructed.
The white fuel tank is unusually clean, with only the XR1 and Bottpower marks breaking its smooth surface. Behind it, a slim single-seat tail rises into a pointed carbon-fibre section. That tail gives the bike a race-inspired profile without adding a bulky fairing or side bodywork.
Flat-track attitude, modern hardware
The XR-1’s flat handlebar and compact proportions suggest the upright, direct stance associated with flat-track machines. The broad front plate is more than a styling flourish: it gives the otherwise open front end a strong visual focal point and houses twin round lamps. A small, centrally mounted gauge keeps the cockpit restrained.
There is considerable contrast between the old-school outline and the detailed running gear. The source lists the Buell 1125R’s eight-piston brake system, with ISR levers for the front brake and clutch. An Öhlins rear shock is mounted visibly beneath the tail, its gold reservoir adding one of the few bright colour accents to the otherwise monochrome build. The black under-slung Torque Hammer exhaust keeps the lower edge of the motorcycle visually tidy while leaving the engine and rear suspension on display.
Function shaping the finish
Carbon fibre appears in the tail and front bodywork, where its weave adds texture against the gloss white tank and dark mechanical parts. The Easton handlebar, Motogadget instrumentation and exposed control cables preserve the XR-1’s stripped-back character rather than pushing it toward a fully faired sportbike.
Bottpower presented the XR-1 as a standalone motorcycle and also described a planned kit for XB owners. Those plans belong to the project’s reported launch context; the enduring appeal of the bike is the way it combines a familiar Buell mechanical package with a much more focused chassis and visual language. It looks less like a modified standard motorcycle than a deliberate re-edit of the street tracker idea.

Built with an ample amount of carbon fiber, Bottpower used the stock eight-piston Buell 1125R Brake system (with ISR levers for the front brake and clutch). For the rear suspension an Öhlins shock has been implemented, while the under-slung exhaust is from Torque Hammer. The flat handlebar is by Easton, while the gauges are from Motogadget.
