This throttle kit is not legal for MotoAmerica Junior Cup. We recommend and use the Motion Pro Rev2 Throttle Kit for all Junior Cup bikes.

*You will need to replace the start/kill switch when you install the Norton Racing Race Spec Throttle Kit on your R3 because the OEM start/kill switch is part of the throttle housing.

There are a few options available for this:

The Motion Pro Yamaha R3 Kill Switch is an inexpensive, plug-and-play replacement switch for the Yamaha R3.

The Yamaha R3 Kill Switch w/ Integrated Keyswitch Elimination Harness is a plug-and-play harness for the Yamaha R3 that also bypasses the OEM keyswitch so the heavy keyswitch can be removed. This is recommended for racers, as it’s a better and cheaper option than purchasing a Kill Switch and Keyswitch Eliminator Harness separately.

It is also possible to use an OEM start/kill switch from a 2006 or newer Yamaha R6, but you will have to splice the wiring or change the plug to adapt it to the Yamaha R3.

*This kit is for closed course use only.
