Supercharged and Nitrous Oxide aren’t words you often hear muttered by builders of Cafe Racers when they are running off a list of modifications they have made to a motorcycle, but Carpy owner of CB750 Cafe, isn’t your average type of guy.
Carpy was missing his Vincent Cafe Racer from his youth so decided it was time to build a bike just as cool or perhaps even cooler (which some may say is an impossible feat). Carpy specialises in transforming Honda CB750s in to fully blown Cafe Racers so a CB would be the base for this new project.
The bike was in a pretty sorry state so Carpy started by stripping it back to the bare frame. With consideration for the extra power the frame was strengthened. Five degrees of rake was added to the neck for a more aggressive stance. And all the welds were cleaned before the frame was given a copper flake paint scheme reminiscent of the 1950’s American hot rod era.
A new tank was fabricated from 3 separate CB tank. The new tank is an extra 4 inches long to ensure the bike would have plenty of juice for long rides. The tank was then given a black and copper flake scheme to compliment the frame.
The 1969 CB7540 motor was blueprinted and balanced before the arduous task of fitting a supercharger was started. After a long running battle trying to get the thing to fit Carpy achieved what he set out to do and had the Super Charger fitted and ready to go. With the Super Charger bulging out of one side of the bike he decided to fit a vintage A.R.D magneto to balance it looks and to provide plenty of spark…which is never a bad thing when adding forced induction to any vehicle.
The bike was then pieced together with a spattering of Carpys custom made parts and polished and painted to custom show standards. Some of the parts found on the bike include:
- Clubman Bars
- Rocket Four seat with Leather trim.
- Italian style rear sets
- Chromed NOS Dresda swing arm
- Alloy Racing Rims.
- Finned engine covers
- Double chain/sprocket set up
- Drilled front disc
- Carpy’s Yoshimura style ehaust
Then to be entirely sure that no one would question this motorcycles cool factor a modest Nitrous system was added for a bit of extra bite and the Honda CB750 Cafe Racer was then given the name “Koppa Kafe“.
