Sparkle and Strength: HONDA CB750F Custom by TTR MOTORS

TTR MOTORS' CB750F

The side covers marked with the “CB890F” logo reveal that this CB750F has been big bored to 890cc. The bike has also been repainted and given a full custom look, but surprisingly, this transformation happened only recently. We asked Mr. Hayashi from TTR Motors about the details: “As the logo suggests, the engine is now 890cc using WISECO 67.5mm pistons, something we had done before. The clutch has been converted to a hydraulic system, and a reinforced generator kit was also installed. The chassis, however, was originally built using CB400SF stock components. Later, when the owner decided on a flashy exterior, we also rebuilt the suspension, wheels, and related components to suit a bike of this class.”

In short, the bike has been updated and optimized. The front end was reworked with a NOBLEST ExM (Exchange Mode) package for the Zephyr 1100, combined with a Yasuda Shokai 43mm fork stem, creating a 17-inch setup. The rear uses an OVER Racing Type-10 swingarm originally for the XJR1300, specially custom-ordered with wide specs to fit a 190mm tire. The wheels are OZ Racing GASS RS-A, with a front wheel for the Zephyr 1100 and a rear wheel for the XJR1300.

The front and rear axles, along with the pivot shaft, were upgraded to chromoly. The pivot shaft ended up slightly longer, so Hayashi adjusted it and re-cut the threads to fit properly. Even as it was, it would have worked, but these refinements eliminate protrusions and create a cleaner look. These choices and precise adjustments are possible because Hayashi has extensive experience with CB-F models.

As for the eye-catching paintwork, the owner had it done by a painter, and it was installed when the chassis rebuild was completed. Despite its bold finish, it blends seamlessly with the bike. With the rear wide tire setup, matching the 17-inch conversion, and fine detailing, the bike achieves a sense of unity that only a shop deeply familiar with CB-Fs could deliver.

Handlebar

The front uses a Yasuda Shokai 43mm fork and 17-inch stem kit combined with a NOBLEST ExM package, with Ohlins RWU forks fitted. Brembo RCS master cylinders are installed on both sides of the handlebar. The meters include a STACK ST200 Clubman tachometer mounted in the stock right-side nacelle, along with a YOSHIMURA PRO-GRESS2 temperature gauge.

Bodywork

The bodywork, finished in metallic paint with tiny glitter flakes, was brought in for installation by the owner.

Engine

The engine features chrome-plated covers as highlights, and has been enlarged from the stock 62 x 62mm to 890cc with WISECO 67.5mm forged pistons. It is also equipped with a Metal Gear Works hydraulic clutch kit (mounted at the rear right of the engine), a reinforced generator kit, and an oil catch tank from Team CB's.

The carburetor is a TMR 36mm with a funnel setup.

Chassis

The rearsets are OVER Racing 4-position for CB750FA-FC, and the sprocket cover (meter gear output type) is made by Metal Gear Works.

The front end uses Ohlins 2IFF5200 forks with Brembo axial 4-piston calipers and SUNSTAR Premium Racing discs.

The rear brake uses a Brembo P2-RS84 2-piston caliper combined with a SUNSTAR Premium Racing disc. The exhaust system is made of steel with a black oxide layer by SSP Factory.

The rear suspension is fitted with Ohlins Grand Twin shocks and an OVER Racing Type-10 swingarm for CB, custom ordered with wide specs. The wheels are OZ Racing forged aluminum GASS RS-A, sized 3.50-17 at the front and 6.00-17 at the rear. The drive chain is an EK530 MVXZ2.
