As you racing enthusiasts know, most factories do not warranty their racing bikes, so you are stuck with what the factory sends-out even if the throttle response is non-linear, too-sensitive, or you experience flame-out tendencies, coughing and choppiness.

Injectioneering is currently focused on the Honda CFR-450 but will soon be releasing similar throttle body modifications for many other racing bikes.

HONDA CFR450

Motocross Action Magazine tested the Injectioneering throttle body unit and was pleasantly surprised at the results. Every MXA test rider was amazed by the improved pickup of the Injectioneering-modified CRF450.

The Problem

As delivered from the factory, the CRF450 exhibits a rather snappy response to relatively small throttle twists. Many riders consider the response too reactive for their liking.

The Solution

With the Injectioneering throttle body, the throttle response starts sooner, picks up quicker, rockets out of corners and is a tremendous improvement.

Although the Injectioneering throttle body only affects the first 25 percent of the throttle position, the surge off the bottom helps the power carry better into the midrange.

At any ability level, testers appreciated the absence of flameout. The CRF can still stall of course, but the trepidation of a cough after chopping the throttle is eliminated.
