Not long ago, you couldn’t open your browser without stumbling across another Honda CB custom. But these days, that honor belongs to Triumph Bonnevilles and old BMW airheads.
The occasional fine CB750 still rears its head. But how many are as good as this absolute masterpiece from Auto Fabrica?
The English shop—founded by brothers Bujar and Gazmend Muharremi—has just worked its magic on a 70s-model Honda CB750 SOHC. All the Auto Fabrica trademarks are present: flawless lines, supreme minimalism, and killer details.
“The ‘Type 13’ was a commissioned project,” says Bujar. “Our client was already aware of our work, and wanted a combination of ideas from our previous builds.”
The client was also dead set on a CB750, having spent his youth on the back of his dad’s ’76. So the guys went back and forth on the design side—including one concept with a fairing—before settling on the classic silhouette we see here.
“The bike needed to have a high level of class with modern upgrades,” says Bujar, “subtle and neatly integrated, even down to the last detail of color and trim. Everything needed to flow.”
And flow it does. Auto Fabrica paired the original fuel tank with a custom-made aluminum tail section that mimics its shape. They’re a perfect match, no matter what angle you’re looking at the bike from.
Move to the back, and you’ll notice a louvered section right below the LED taillight. “It’s become a signature touch on all of our builds,” says Bujar. “The fin spacing is similar to the engine fins.”
Auto Fabrica also wanted to ditch the bulky oil tank, so they fabricated a new one inside the main tank. The oil lines now run neatly behind the carbs, and out of sight.
The frame was de-cluttered as well, and re-worked in certain areas. This included fettling the rearset placement to accommodate the new exhaust system—an exquisite four-into-four, stainless steel affair, with internal baffles.
“Our client is a regular track day visitor,” says Bujar, “and he always loved the idea of turning up to the track on the Type 13.” With this in mind, the guys stiffened the frame with an ‘X’ brace behind the carbs, and a single tube brace under the exhaust headers.
They also upgraded the suspension, with rebound-adjustable front forks and YSS rear shocks. Brembo brakes were installed all round, with a disc fitted at the rear via a custom adaptor plate to fit the OEM hub.
The wheels are a 19″ front and 18″ rear, laced with stainless spokes and fitted with Avon Road Rider tires.
The engine was treated to a complete rebuild, complete with an 836cc Wiseco kit, and a ported and polished head. The carbs have been fully rebuilt too, and are fed by custom velocity stacks with internal mesh. All wear and tear items were replaced.
Bringing the CB bang up to date is a new wiring loom—built around a Motogadget m-Unit control unit, and finished with a Motogadget speedo. The new switches are particularly trick: they’ve been integrated into the controls’ clamps.
It’s just one of many little details at play. Note the stainless steel, brass-brazed clip-ons, and the hand-sewn leather grips, complete with turned brass bar-ends. Naturally, they match the saddle—which has been adorned with a small plaque bearing Auto Fabrica’s logo.
There are no afterthoughts here; even the turn signals received extra care. The rear ones are tucked into the frame rails, while the front ones are integrated into the bottom yoke.
Finishing everything off is a typically subtle color scheme: gunmetal grey throughout, with components like the engine casings and levers aqua-blasted and brushed.
“We had a great time building this one,” says Bujar. “It’s the first proper four-cylinder bike we’ve tackled. We now have a whole fleet of fours coming up—they’ll be evolutions of what we’ve learned here, plus additional ideas.”
If this is what a CB750 revival looks like, count us in.
