One wicked muscle bike

Victory Motorcycles confirmed it is indeed producing a liquid-cooled engine for an upcoming 1200cc motorcycle. The powerplant, based off the engine from the Pikes Peak racer Project 156, is a 60-degree V-Twin with four valves and double overhead cams. Victory said it shares the same crankcase, V-angle, rotating bottom-end, transmission and clutch setup as the Project 156 engine.

The liquid-cooled engine is a first for Victory, which has used the air-cooled Freedom 106 V-Twin to power all the models in its current lineup. It signals the new direction Victory has taken of late, which includes the Victory Empulse TT electric superbike, a Gunner turned NHRA Pro Stock drag bike, and the aforementioned Project 156.

Swiss builder Urs Erbacher of Fat Attack Custom Bikes AG built one wicked muscle bike around the pre-production liquid-cooled Victory powerplant. 

To showcase its new powerplant, Victory shipped a pre-production engine to Swiss custom builder Urs Erbacher of Fat Attack Custom Bikes AG to wrap a bike around it. Erbacher knows a thing or two about going fast as a multi-time drag racing champion of both Funny Cars and Top Fuel dragsters. The result is the Victory Ignition Concept, a wicked muscle bike with a cast aluminum frame, high performance suspension and premium brakes. Based on initial reactions, we don’t think anybody would complain if Victory adopted Erbacher’s design for its production bike.

“I’m proud not only of this build, but what it represents for the future of the Victory Motorcycles brand,” said the Swiss builder in company PR. “Getting full reigns to wrap the new engine in an interesting bike is a real highlight in my career – and I imagine that any production bike utilizing this powertrain will be a fantastic ride.”

Besides the information listed above, Victory has remained tight-lipped about the specifics of its new engine. Luckily, they did provide more details about the splendid Victory Ignition Concept Erbacher built.

Erbacher examined Victory Motorcycles’ existing cruiser lineup and created a concept that would put the new V-Twin engine at the heart of the bike.

This has the same base architecture in the prototype engine used in Project 156 – the crankcase, V-angle, rotating bottom end, transmission and clutch setup are all the same. The liquid-cooled four-valve engine has double overhead cams with the aim of making class-leading power. Additional details of the engine will be revealed in the months to come.

Erbacher and his team have handcrafted twin headers that snake out from the cylinders into a single pipe and then into an Akrapovic muffler. The idea is to create the shortest exhaust for maximum performance.

The front and rear suspension are adjustable. Marzocchi forks stand proud at the front, and Erbacher explains why: “We have used the same forks on our ‘Erbacher The One’ custom bike for the past three years. The forks are really nice to ride with, and they absorb a lot on bad streets. The good thing is, we can also mount the Brembo brake on this fork and it brakes like a race bike.” Erbacher and his team fitted an Öhlins shock at the rear between the frame and the swingarm.

Erbacher chose 17-inch wheels made from aluminum. “These are superlight and are the right size for the Metzeler Racetec Interact tires we are using,” says Erbacher. “They give the bike a great look. We chose the red color as a nod to the Project 156 bike.”
