Honda CB750F Cafe Racer by Wrench Kings

Honda CB750F Cafe Racer

The Netherlands has become a real hotbed of custom motorcycle culture, and the Wrench Kings are right at the leading edge, turning out some incredible bikes. Now Bram and the boys are back with a ’77 Honda CB750 Super Sport cafe racer. In a world chock-full of CB builds, this bike truly leaps off the screen. The ‘Kings managed to retain the classic aesthetic of the “original superbike,” while bringing the machine into the modern age…and making it rideable for 6.2 foot client!

Honda CB750 Super Sport Cafe Racer

As you may know, Honda introduced the CB750F Super Sport in 1975 as a response to Kawasaki’s mighty Z1. The bike offered a 4-into-1 sport exhaust, slimmer tank, rear disc, stiffer suspension, reduced trail, and longer swingarm. Cycle magazine’s dyno-testing revealed 58 horsepower at the rear wheel — up considerably from the K model — and this brought quarter mile times down into the high twelves.

CB750F Cafe Racer

Early 2016 we received a call from Lex, the owner of NoutDesign Ontwerp & Concept, a modern and successful advertising company in Holland. He had a 1977 Honda CB750 in a nearly original state and had plans to rebuild it in a cafe style. The beginning of something great! Or was it? It did not take long for him to realize his talents lie in advertising more than building bikes…and he needed some assistance to finish his project.


A 1977 CB750…of course we liked the challenge! How to create a clean look from a bike with a dry sump and an external oil reservoir? Move the oil tank to the seat! Easier said than done, but look at the result! It took some trial, error, sweat, pain and the assistance of Marcel van der Stelt (an expert in all custom aluminum solutions) and the result is stunning! A seat pan with an integrated oil tank in the seat. The seat upholstery is made by Toni’s CustomWorks, a new player in the custom seat scene from the eastern part of Holland.

Lex was very specific about his wishes. As the owner of an advertisement company, he had the perfect picture of his bike in mind. A stunning bike with an overhauled engine, perfect finishing and his own design on it! This is how we started. The engine was overhauled and is ready to run miles and miles more. We took the bike apart to the last bolt and rebuilt it with freshly powder-coated parts.


Lex supplied us with a stunning new polished aluminum triple clamp. We designed the aluminum seat with oil reservoir and had it built by Marcel. We had some good times with the guys making hydraulic hoses. They are used to heavy machinery and we came requesting the most minimized solution to fit their hoses to our seat, in which the bendability of the hose was crucial. They had to be hidden underneath the seat and behind the frame!


Of course we made a new wiring loom for this bike and with that we had fun again. This 40 year old bike has an RFID tag as an ignition switch now. Tail lights combined with brake lights and blinkers and a big yellow head light and, very subtle, hidden blinkers in front. And Lex is a tall guy. This bike had to fit his 1.90 mtr (6.2 ft) length and to make his seating position comfortable, we extended the foot peg location.


At the time of the photo shoot, rain was pouring down. Typical Dutch weather. Hence we asked our neighbor, a cool blacksmith with an even cooler workshop (with classical music!) to have the shoot in his working place. This made for some pretty cool pics with the forge on the background.
