The Dynojet 250i

Discover your motorcycle’s potential!

Prairie Harley-Davidson's® Dyonjet 250i motorcycle dynamometer is the most accurate and consistent dyno available in the market today. We are very excited in being able to provide you and your motorcycle with this unique experience!

The Dynojet 250i is a sophisticated tool used for measuring horsepower, torque, and for tuning your motorcycle for optimal performance. It is capable of measuring up to 750hp and 858 lb/ft of torque. It can also be used for detecting drive train issues, clutch slippage, ignition misfires, improper air/fuel ratio, and much more!

For tuning your motorcycle, the Dynojet 250i uses state of the art software in combination with an  air/fuel probe, an eddy current load absorption unit, and many other sensors that measure engine temperature, trouble codes, humidity, air temperature, and pressure. It accurately reproduces real world conditions, as though you are actually driving down the road and not just on a freewheeling drum system, as is used on many other dyno models. This gives us the ability to tune your motorcycle to its full potential!
