Short Throw Throttle w/ Grip for Yamaha, Kawasaki (OEM R6 Throttle Tube)


*Install throttle tube with plastic washer outside of the throttle housing, or remove plastic washer completely.

You can get the matching left side grip here if you need so you don’t have two different grips.

Don’t forget, the shorter you make the throttle throw, the harder it is to twist the throttle, since the force necessary to twist the throttle increases 1:1 as the distance decreases. So if you cut the throttle throw in half with a race throttle system, the force to pull the throttle is doubled and it starts to be annoyingly difficult to twist the throttle and your grips will start to spin.

You can solve this with the Norton Racing Soft Pull Return Spring

Norton Racing Soft Pull Throttle Return Spring – Yamaha R3 / MT-03

Norton Racing Soft Pull Throttle Return Spring – Kawasaki Ninja 400 / Z400


This is an OEM throttle tube from a 2008 Yamaha YZF-R6 with the OEM grip installed.  This throttle tube will fit the Yamaha R3.

The OEM throttle tube on the Yamaha R3 requires a very long twist to reach full throttle.  The OEM throttle tube on the Yamaha R3 also has molded plastic texture on it to prevent the grip from moving while riding.  However, these molded plastic bumps on the throttle make it very difficult to replace the grip with an aftermarket grip.  You have to grind off the bumps or they will stick through the new grips.

By replacing the OEM Yamaha R3 throttle tube with this Yamaha R6 throttle tube, you eliminate both of these problems.  This R6 throttle tube will shorten the throttle throw by 15-20%.  This is very helpful to reduce wrist pressure, and make it easier to twist to full throttle without having to re-grip the throttle.  This R6 throttle tube is also smooth on the outside, so you can install any aftermarket grips you like.  The only modification to install this throttle tube is to loosen the throttle cable at the adjuster and this is very easy to do in just a few minutes.

For installation on the Kawasaki Ninja 400, follow the instruction in our write up here: How to install an R6 throttle tube in the Kawasaki Ninja 400 / Z400

    This is really the best bang for the buck upgrade for the r3. Takes all of about 20 minutes to put on with just a screwdriver. Instantly improves the feel of the bike. The power comes up much quicker and no need to change your grip. This should be your first upgrade before anything else

    I live in Minnesota and I received this in 3 days! Thanks YamahaR3racing. Easy install had to adjust the throttle cable of course. It would stick when the wheel was turned to the extreme left. No big deal just loosened it a couple more turns from stock.

    Awesome inexpensive mod that you definitely notice when you go for the first ride after installing. You don’t have to bend your wrist all the way back to go WOT with the r6 throttle tube.

    Will this fit the 2020 Yamaha mt-03?

      We have not tested this mod in the 2019+ throttle housing.

      ***Update*** We have had customers confirm that are using this mod with the 2020+ Yamaha R3 and MT-03.

    This was an absolute NO-BRAINER. Top marks to Jesse and the team for making this available, and the addition of the OEM grip is a real professional-touch. Thanks, again.

    will this work with heated grips? thank you in advance.

      I don’t see why not.
