1147cc CBX from a restomod master…
Ten years after their introduction of the CB750, Honda unveiled the CBX 1000 — a six-cylinder, 1047cc superbike intended to show the world they were still the tip of the spear in the motorcycle game. According to the bike’s designer, Shoichiro Irimajiri, who’d previously developed Honda’s six-cylinder GP race engines, the CBX was about far more than performance figures and numbers on paper:
“There was something exhilarating and exciting about the 6-cylinder CBX that was lacking in the 4-cylinder… something in the CBX that could not be measured in numbers like speed and weight, (which) made it a very sexy machine.”
The bike made 103 hp at 9000 rpm, good for a quarter-mile time of 11.3 seconds — not bad for a 600-lb machine. While the CBX remains a vintage legend, modern riders complain of the bike’s inadequate brakes, flimsy chassis, and overall girth.
Enter Darren Begg of Canada’s dB Customs, who’s been making a name for himself building some of the sexiest air-cooled restomod superbikes on the planet. The recipe is deceptively simple: stay true to the original style of the machine while upgrading the suspension, wheels, brakes, geometry, and power.
In this case, Darren had originally built a CB900F restomod for a client in New York, who also happened to be the original owner of a ’79 Honda CBX. While the bike already sported some cool 80s-era parts, it still needed the dB Customs touch…
“It seemed to have an identity crisis and needed a lot of updating and dB Customs styling cues to make it a modern restomod monster.”
The full arsenal of upgrades is listed below, including Öhlins suspension, aftermarket swingarm, Brembo brakes, carbon-fiber wheels with Avon sport rubber, a new wiring loom and ignition, and a fully built 1147cc motor with JE pistons, Web cams, Carrillo rods, Xtreme Motorsports head, and a hand-bent titanium 6-into-1 exhaust.
All in all, this has to be the sexiest CBX we’ve seen, a super six that’s 135 pounds lighter than stock! Says Darren:
“What makes me most proud is that I was able to take a bike that normally weighs almost 600 lbs (wet), down to 464.5lbs (with oil, brake fluid, and ¼ tank of gas).”
Below, we get the full details on this stunning machine.
Honda CBX 1000 Restomod: Builder Interview
• Why was the bike built?
dB Customs built a CB900F restomod (985 Evolution) for a customer in NY and he loved it so much that he returned for a follow-up build on his CBX (original owner). The bike had some really cool parts from back in the 80’s (PM wheels, Calfab swingarm, Kerker exhaust), however it seemed to have an identity crisis and needed a lot of updating and dB Customs styling cues to make it a modern restomod monster.
• Design Concept
Customer wanted all the restomod features that dB Customs is known for (Öhlins suspension, Brembo brakes, high-output engine with race carbs and exotic exhaust, high-end wheels, etc).
• Can you tell us what it’s like to ride this bike?
Haven’t ridden it yet. Winter hit shortly after the bike was completed and photographed. Bike is in storage until Spring at which time it will be test ridden.
• Was there anything done during this build that you are particularly proud of?
I was never a big fan of the CBX, however as I was taking the pictures I thought to myself, wow, this thing is absolutely stunning, has the perfect stance, looks balanced (design wise), and looked nothing like any CBX I’ve ever seen before. What makes me most proud is that I was able to take a bike that normally weighs almost 600 lbs (wet), down to 464.5lbs (with oil, brake fluid, and ¼ tank of gas).
