Chino, Calif. - Febuary 19, 2010 - Yoshimura knows a lot about Suzuki's QuadRacer R450 and QuadSport Z400. A couple of Championships by Dustin Wimmer and Doug Gust are proof of that. Over the years, a number of weight saving and power boosting solutions have come out of R&D, plus a couple of items that are just cool.
Parts for QuadRacer R450 Only:
Radiator Guards
We spent a lot of time and bashed many knuckles cutting up RM-Z450 radiator guards and shoe-horning them into the QuadRacer R450 shrouds. Then we figured we'd be better off making some of our own. Our R&D guys fixed this problem in about five days...and knuckles everywhere rejoiced!

Blocks debris from getting to the radiator
Race team tested Part #: 2115-RADFIN
MSRP: $99.95
Kick Start Kit
When you're racing, every ounce counts. That's why the Yoshimura Kick Start Kit is so popular. It shaves off nearly eight pounds from your quad, taking a lot of that "high weight" off. Highly placed weight can negatively affect the polar movement of your quad and cause negative handling forces. This kit also reduces the mass on the crankshaft, making for snappier overall performance. While we were improving things, we included a capacitor to replace that clunky battery and make things nice and "sparky." A Yoshimura Shift Pin Kit is also included to toughen up the engine cases.

Push Button Start Kit
Get rid of unnecessary bulk with the push button start kit. It eliminates the stock handlebar switch assembly and allows for a less cluttered handlebar area to mount hand guards or reposition controls. This kit is built specifically for the Suzuki QuadRacer R450 using OEM spec switch, harness and connectors.
Part #: 2115-PBS
MSRP: $24.92
Spark Plug Holder
When you're racing, the win and valuable series points are on the line. Don't let something like a spark plug cap blowing off in the middle of the race ruin your championship run. It happened to us once, and after that we made these handy little hold-downs that ensure we won't have to go through that again!
Keeps spark plug cap in place
Made from high-grade aluminum Part #: 2190-SPH-K
MSRP: $24.95
Parts For QuadRacer R450 and QuadRacer Z400:
MXR-8 Wheel Cap
Pick your favorite color: red, black, or yellow. Rotating mass can cause your tires to become off balance and cause axle vibration, so we designed these caps to keep sticky, heavy mud out. These wheel caps push into most 8-inch beadlock rear wheels. Trick Yoshimura wheel cap stickers are included.
