Team CB's CB750F

The CB750FC built by TEAM CB is characterized by its rocket cowl. After establishing dominance in the U.S. market with the CB750Four, Honda introduced the CB900F to expand its brand presence in the European market. One of the concepts behind the CB900F was an angular exterior design inspired by contemporary arts and crafts of the time. So, how does the rounded rocket cowl complement this design?

The CB-F was released at a time when the concept of cowls and aerodynamics was introduced to commercial models. The CB750FC Integra, featuring a round headlight enclosed by a square-shaped cover was designed to harmonize with the CB-F's original linear design. The reason why such a full cowl had not been seen before is likely because many Honda customers, especially CB-F fans, preferred the stock design. Mr. Yasuda, who carried out this project, took on the challenge of combining the '70s and '80s era CB-F with the Rocket cowl which evokes a strong nostalgic impression. The seat was changed to a single seat to match the style, and lines were added to the cowl to align with the CB750FB stock pattern for coloring. Initially, there were many negative reactions, but as the work progressed, Mr. Yasuda gradually received positive feedback from people around. Apart from the cowl and the seat, thorough restoration work was undertaken to create a straight 18-inch wheel custom style. The result is a delightful variation that effectively captures the essence of that era.

Bodyworks

The rocket cowl is an aftermarket part made of FRP for the Kawasaki Z series. It was modified for installation, and painted using the CB750FB stock pattern.

The single seat with some tuck-roll type pattern is made by TEAM CB. Other exterior parts remain stock.

Handle

The top bridge is replaced with of a CB-F/R handlebar kit 39, and Hurricane's clip-ons are cramped on the stock front forks. The clutch is hydraulically driven by a Metal Gear Works hydraulic kit to lighten operation, and NISSIN radials are installed in the left and right master cylinders.

Intake & Exhaust

The silencer is a Moriwaki short steel silencer (one-piece full exhaust). It is a better choice to keep the overall uniformity of this custom.

Engine

The engine is an air-cooled DOHC 4-valve straight-4 CB750F, which is in good shape and is retained as stock. An 11-rows oil cooler can be seen inside the front cowl. The carburetor is a CR Special Φ29mm, and although many CB-F owners stick to the stock setup, Mr. Yasuda says that using a new carburetor such as FCR is also recommended for good performance. In the case of it, the carburetor was replaced with FCR later on, and the footpegs are TEAM CB's original, reminiscent of the time when the CB-F was still in produciton.

Bodyworks

Φ39mm front forks with TRAC are a stock CB750FC part. The front brake system is also a stock part of the CB750FC, with a single 2-piston caliper and Φ276mm disc.

The rear brake system using single-piston 2-piston caliper and Φ276mm disc is also the stock. The rear shock is a YSS Z362, but the round pipe swingarm is retained.

The front and rear wheels are forged aluminum PMC's Sword Heritage 2.75-18 / 4.00-18. The drive chain is RK and the sprockets are made by X.A.M.
