Triumph Rocket III
Carpenter Racing, the industry’s
leader in motorcycle horsepower enhancement and high-performance
component design and development have set their sight 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.
And wake up it did
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 produces
an incredible 230+ horsepower to the rear wheel.
“This thing is so strong, at 700 pounds you don’t need 1st
gear,” said Carpenter 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.”
And that is only the beginning. Carpenter already has his eye on
the next version.
"At over 700cc a hole this thing is hungry for a big valve,” he
said. “When we get serious with this next version I am sure we
are going to hit 280 horsepower without making it any bigger.”
For now the 230 package is available. Choose the “Drive-in,
Drive-out” and leave Carpenter Racing with a turnkey, tuned
motorcycle. For the mail order package send us your head and
cams and we will ship it back ready to bolt on along with the
other components.
