The Honda CB750 4 is, surely, an iconic bike. It’s been labelled as one of many best bikes ever made, holds a revered place within the AMA Bike Corridor of Fame and has even made an look on the Guggenheim Museum. It was the primary manufacturing “Superbike” to hit the streets and from 1969 to 1978 the Japanese producer offered over 400,000 Ok sequence SOHC CB750s (K0 by means of to K8).
The mighty CB750 additionally grew to become the poster baby of the ‘new wave’ customized scene in the course of the late nineties because of its traditional beauty and comparatively reasonably priced secondhand value. Lots has modified since then although. Ok sequence CB750’s have turn into scorching property and first rate early fashions are fetching some fairly hefty sums. Luis Martins of Lisbon’s Cafeina Bikes is nicely conscious of the CB’s esteemed standing. He’s been racing bikes for nicely over a decade and constructing them for practically as lengthy. So when the chance got here to work on a Ok sequence CB750 he determined to method the construct a bit in another way.
Somewhat than remodeling his 1978 Cb750 4 K8 donor into one thing it was by no means meant to be, Luis opted to carry out a resto-mod. This meant retaining the bikes traditional beauty however upgrading its efficiency utilizing fashionable parts.
The challenge started with a whole overhaul of Honda’s suspension. On the entrance finish, he swapped the ’70s customary forks with a set of inverted gadgets from a Yamaha FZR 1000. The trendy forks have been retrofit to the body utilizing a specifically modified triple clamp. Luis says the brand new configuration has “made the steering angle extra incisive with regards to predicting any curve, with out hesitation and with precision.”
By repurposing the unique prime clamp Luis was in a position to retain the Honda’s top-mounted handlebar setup. The brand new bars sits decrease than the originals however they’re carrying the inventory controls and sit behind the bike’s unique twin gauge meeting.
On the rear of the CB is an much more dramatic change which brings the bike up to the mark with twenty first Century sports activities bikes.
The Honda’s rear wheel is now supported by a mono-shock arrange which was repurposed from the identical donor because the entrance finish. Together with the shock itself, Luis has shoehorned the FZR aluminium swingarm into the CB body. It’s an unlikely pairing, however the payoff in dealing with enhancements was clearly definitely worth the effort. To get the entire setup to work Luis has welded mounts for the shock to the inventory chassis. Though he’s misplaced the traditional twin shock look the revised rear finish is far more svelte than the unique and he’s dropped a bunch of unsprung weight.
One other large enchancment that may be attributed to the tasks Yamaha FZR 1000 elements donor are the brand new brakes. This CB now bites down on a pair of 320mm discs through 4 piston callipers on the entrance and a complimentary arrange within the rear. The wheels too are tailored from the FZR. They’ve been rebuilt and provide extra grip because of their wider profile and fashionable rubber.
With the engine, Luis has carried out a full rebuild and retune. The largest modifications of be aware is the blacked-out paint scheme with shaved cooling fins, the elimination of the airbox and his method with the exhaust.
Again when Honda launched this CB750 a typical aftermarket modification was to swap out the 2-into-2 pipes with a sporty 4-into-1 system. So that is precisely how Luis approached his exhaust overhaul. By likelihood, he stumbled upon an unique system from again within the day with a traditional megaphone muffler. The brand new pipes add simply the correct amount of visible and audible muscle to let individuals know this roadster means enterprise.
In line with his method of retaining the CB’s period-correct look, the bodywork of the CB is all unique Honda tools. The gasoline tank, tail unit and facet panels are all repurposed from a CB750F of the identical period. The flip alerts are F sequence too however he’s carried out away with the mess of plastic beneath the tail to tidy issues up.
To finish his Honda CB750 Hanashi (story) Luis retained the unique Honda badges however put collectively his personal paint scheme. In these pictures, the bike seems black but it surely’s truly a deep metallic brown with a metallic gold peppered by means of it. He says in direct daylight the bike takes on a complete new look that must be seen to be actually appreciated.
We’ve seen our fair proportion of closely customised Honda CB750’s but it surely’s the understated excellence of this bike that makes it one thing particular.
