Kawasaki 400cc /Yamaha R-3 lightweight throttle body pull/return spring is engineered, designed and Manufactured in the USA. The purpose of this new design is to allow the rider (s) to have a softer (Approx. 20% Less) for more controlling feel to their throttle. The OEM throttle body pull/return spring is designed with the “Commuter” mind set, a little stiffer pull and a hard return to make sure that the throttle body does return to full close. The OEM Throttle spring has little to no feeling when you pull/rotate the throttle and this can be troublesome when you are mid corner ,laid over this engineered Spring will add a more comfort/confidence once installed. This works on Both the Kawasaki Ninja 400 as well as the Yamaha YZFR3
Spears Racing had looked at several of the “Lightened Pull springs” on the market the inconsistency from one to another has made us decide to make our own that is engineered to the nth degree to make sure that all of our customers know that it is a purpose built spring.
Spears Racing has been designing and making race products for decades, their continuous committed to excellence to advance as the industry changes. This commitment has resulted in more components specific to certain applications, proprietary products only manufactured for us.

RACE USE ONLY
This Kawasaki 400cc /Yamaha R-3 lightweight throttle body pull/return spring is designed and Manufactured in the USA, Torsion springs are designed to store and release rotational energy, primary characteristic of torsion springs is that they reduce in body diameter and increase slightly in body length when diverted in the direction of the wind. This type of spring can hold a mechanism in place by positioning the legs across the centerline axis. No matter the material, torsion springs, by design, are able to return to their original position once rotated a safe degree of deflection. However, that capability does diminish if the spring is rotated too far or what spring manufacturers call “overstressed”.
Spears Racing has been on the cutting edge of making new products for the little commuter style bikes for decades, most of these products come from the motorcycle being used for something other than what it was intended to be use for…RACING!!
