Starting with a 1973 BMW R75/5, we repaired and braced the frame along with removing the factory tabs before refinishing in a gloss black powder coat. We fitted our custom subframe with a flush mount brake light and turn signals. The front end consists of a pair of Showa USD forks mounted via a custom triple tree, whilst rear suspension is equipped with a pair of Öhlins shocks with external reservoirs. The exhaust is a full stainless system finished with a pair of quiet-core mufflers from Cone Engineering. The result is a classic café racer with modern handling characteristics, excellent brakes and ample power.
The original engine has been rebuilt with displacement increased to 1000cc and a compression ratio of 9.0:1. The heads have been refurbished and a hi-output ignition system powers a single dual coil mounted under the tank. The Mikuni carburetors have been jetted and tuned to suit. The factory airbox was drilled in the style of a 1977 R100RS. The starter was upgraded to a lightweight hi-torque unit to take less draw the from lithium battery, housed safely under the gas tank in our custom battery tray. The factory charge system was replaced with a modern upgraded unit
A /5 headlight bucket is mounted to a pair of Showa USD forks. Brakes consist of a pair of Brembo radial calipers operated by an under-tank master cylinder. The headlight has been modified to LED for brighter light and less draw on the battery.
A new Motometer Speedometer incorporates a tach and indicator lights. Hand controls are new OEM units, modified to suit the custom wiring harness. All original hardware was zinc plated.
