Marine Turbine Technologies is a company located in Franklin, Louisiana that specializes in turbine engines being used for industrial applications. Some of their products include water pumping for fire fighting or flood control and generators. However the company also makes a motorcycle called the “420RR” that’s powered by a Rolls Royce Allison 250-C20 series turbine. They are found in Bell helicopters and produce 420 horsepower and 600 lb-ft of torque through a two-speed transmission. The first gear is good until about 100 mph. The transmission fluid, turbine fluid, and part of the fuel (diesel or kerosene) is held in the custom aluminum frame.

It’s beautiful!
I had a friend that had been an electrical engineer for Rolls Royce Aircraft in England and he told me about a motorcycle that had been designed and built by several engineers at that company but it was discovered by the management and it was scrapped before it was completed as it was a “secret” project. He told me of many of the details of how it was designed with several people involved but it was not explained how they thought that they would get it out the door.
In the Daytona Speedway Infield, I watched a British (I assume) motorcycle with a Rolls Royce turbine engine being unloaded for display. Labeled the 420RR. Looked potent for sure.
