The Honda CB750K was first introduced in the late 60’s as a concept in the Tokyo Motorshow. When production numbers started hitting the road in the 70’s it was an instant success and redefined an era. It was the first Superbike, and with good reason – the engine’s power and reliability were particularly impressive at the time. What followed were years of Honda domination, and countless competitors entering the space. The design of the Honda CB750four and the likes of similar manufacturers almost completely displaced other European manufacturers like BMW, that simply struggled to keep up.
50 years on, and these beautiful bikes are worthy of complete restorations. Or if you’re like us, complete transformation to something modern, but also oh so vintage at the same time.
This CB750K cafe racer build was featured on the likes of Pipeburn, Bike Exif, and much more. We spent over 200 hours perfecting the design of this bike to become a modern cafe racer with a very 1970’s period correct finish. This included the likes of a completely modern front and rear end swap, YSS suspension, complete motogadget fit-out that includes LED lighting, keyless start & go, and so much more. The tank was coated in a Soul red candy paint with layers of clear that were sanded back to a translucent mirror like finish – because it’s a vintage Honda, and nothing else seemed as appropriate. What’s more is this bike has countless one-off unique items like suspension bolt covers, kick-start grips, crankcase breathers, and other items that were fabricated in-house on our lathes, mills and other fabrication equipment. We hope you love it as much as we loved working on it, and our client loves riding it!
Modifications:
- Cleaned and reduced frame by shortening rear sub-frame. Slipstream rear-sets, re-fabricated with bespoke linkages for far better feel during braking and shifting.
- Complete paint-job to engine, swing arm and frame (satin black for mechanical and high gloss for modified frame).
- Engine re-tune, and all stainless nut & bolt refresh to all external covers. This also includes a crank-case breather that was fabricated specifically for this engine.
- Custom fabricate oil tank of the same capacity relocated directly behind the Mikuni carbs to give the book a very light-weight look. The oil tank also received custom oil filler cap, and dipstick, all machined in-house.
- Upgrade from the stock Keihin Carburetors to RS34 Mikuni Carbs, with a set of aluminum velocity stacks so it breathes in a lot more air. According to Mikuni, the flat-slide carbs, which have a very distinctive rattle when at idle, give an additional 25% power.
- The classic Honda CB750 fuel tank brought back to life. Lots of panel beating, sanding and love and care went into this tank. The colour is a Soul Red Candy (4 coats on top of 3 coats of silver base) + 4 coats of clear coat. It was then sanded back until any orange peel was virtually gone to reveal an almost glass like finish. The chrome fuel cap on top just finishes it off.
- JAX Garage Honda CB750 – 7 Series fork conversion kit to hold in place Honda CBR929 forks and front end. Front-end forks were re-painted with an anodised red coating to match the colour-scheme of the tank.
- Custom front and rear brake reservoirs, and custom HEL braided brake lines courtesy of GK Tech.
- Custom YSS RC-CB-302-T piggy back shocks, all black (Custom colour – Custom length to suit – and custom bolt-end covers machined in-house for an ultra-tidy finish).
- All JAX Garage billet aluminium grips, and Clips on handlebars, to match perfectly with Motone switchgear, motogadet bar-end street mirrors, and mo.blaze disc indicators.
- Complete motogadget and lithium battery fit-out. That is, complete keyless start, bluetooth connectivity, all powered by an AG801 lithium battery and Ricks’ regulator rectifier to suit.
- Modified electrical wiring and removed original instrument cluster. Instrument cluster is now ultra clean with the help of a motogadget chronoclassic speedo.
- Ducati Monster 3 Spoke alloy to match the front. One of the hardest parts of the build was integrating the rear wheel on this bike. The wider diameter wheel required a custom offset front sprocket to align the chain. The rear required modification to the rear shaft in the form of a sleeve/bushing, and custom axle spacers.
- Lossa Engineering cone muffler to suit, with an in-house slip-in silencer to meet noise regulations for pre 89 vehicles.
- Front Tyres: 120/60 ZR 17 Rear Tyres: 160/60 ZR 17 – Rubbers = Pirelli Diablo III’s at the front and back.
