​​Can I reduce 1st gear 70% or 45% only?

No. The maximum percentage available for a 1st gear reduction is 30%. Doing only the 1st gear reduction requires the purchase of an additional modified gear set that will provide an ample amount of clearance.


Frequently Asked Questions

What special products do you have for the SS model?

-The GSC Module (Gear Shift Controller) is required in order to change any gears inside the SS transmission. The GSC is a stand alone computer system that works in conjunction with the Yamaha wiring harness. It can be programmed according to the tire size and gear selection the vehicle is equipped with. The GSC does not affect any aftermarket tunes or ECU re-flash.-The IRP (Initial Response Plate) is a new pressure plate that works in conjunction with the Yamaha clutch and shift actuators, allowing the SS the to begin moving at 200rpm. This feature is GREAT for slow speed driving in any scenario: loading on a trailer, crawling up a hill, towing or starting in precarious situations where gaining momentum without spinning the tires is crucial. The pedal response is similar to a Rekluse clutch on a standard model or a CVT clutch on competitor’s vehicles.

Is 5th gear a reduction gear set?


No. Our 5th gear is an OVER-DRIVE gear set that adds an additional 15% of speed to 5th gear. Depending on what combination 5th gear is added to there are varying levels of increased performance. If 5th gear is added to a stock, unmodified transmission, you will receive +15% over drive. If 5th gear is added to a transmission with our 15% reduction drop set, you will receive 1% REDUCTION from stock. If 5th gear is added to a transmission with our 30% reduction drop set added, you will receive 15% REDUCTION from stock.

​​How do I get the 45% or 70% reduction in 1st gear?

When you combine our 1st gear set to either of our input drop set gears, it compounds the ratios together and gives you additional reduction in 1st gear. Since 1st gear only provides 30% reduction, when compounded with the 15% drop set you get close to 45% reduction 1st gear. When our 1st gear is compounded with the 30% drop set you get close to 70% reduction in 1st gear.


​​Can I reduce the entire gear box 15%? Can I reduce the entire gear box 30%?

Yes. In order to change the entire gear box only 1 gear set needs to be replaced. The input gear drop set will reduce 1st-5th + reverse. Two ratios are available: 15% reduction and 30% reduction.


What is your clutch mod and why do I need it?

Our clutch mod is a modified inner clutch drum that has been machined, ported and plated, then sealed to "pressurize" the clutch system in order to force oil through the clutch packs. This process ensures that all of the discs are lubricated and cooled.


​​Can I reduce certain gears more than others?

No, only 3 gear sets are available for purchase: 1st gear, 5th gear, and input gears. There is no way to modify any other gears in the transmission.
