Triumph Rocket III

Back in 2009 Carpenter Racing, the industry’s leader in motorcycle horsepower enhancement and high-performance component design and development, set their sights on a new project: the Triumph Rocket III.


The Triumph R3 is a heavyweight muscle-touring bike. Think England’s cross between a V-Max and a Valkarie. It has a massive, 2300cc inline 3-clyinder engine producing 120 horsepower and over 130 foot-pounds of torque.

“We saw the big engine and said ‘This monster needs to wake up!’” stated Bob Carpenter in 2009.

The team at Carpenter took the head and applied their signature CNC porting. They then mated it with a custom-ground, aggressive cam, titanium retainers, shim-under tappets and specialized springs. Custom-designed forged aluminum pistons keep the same weight as stock units to retain proper balance but raise the compression to 11.4:1. New clutch springs and a higher volume fuel pump round out the package.

The results are impressive. With stock valves the bike produced an incredible 230+ horsepower to the rear wheel.

“This thing is so strong, at 700 pounds you don’t need 1st gear,” Carpenter said of the prototype machine. “All we basically did was put more fuel in it and let it rev up. The limiter comes in at 5,800 rpm. We had ours up to 9,000.”

“Nobody is beating our Hayabusa's and 1000’s,” he continued. “And nobody is going to beat this bike. We think the Triumph, even with all its mass, will be a contender. We think this bike will give the Hayabusa a run for its money.”

Since then Carpenter tweaked the head-cam-piston package to reliably pump out over 240 horsepower.  We have also added an entry-level package of just the head and cam work without the pistons that produces over 210 horsepower.

We have also produced a stainless steel exhaust system for the Rocket III.

But that is not all.  Triumph North America noticed our efforts and is supporting us in developing "Project Silverback", our production version of the Triumph Rocket III.  Read about Project Silverback and our real-world dragstrip testing with the following articles:
