The TW GSC (gear shift controller) is required for gear ratio changes in the SS Model YXZ. Our GSC utilizes advanced realtime processing technology to allow any aftermarket transmission ratio to function seamlessly, without modifying the stock Yamaha ecu and sensors. It also allows the speedometer to read correctly based on tire size and gear selection.
- All data is proprietary to Tubeworks Inc. and programmed to work with your vehicle and its specific gear selection and tire size before being shipped.
- If and when you change your tire size you may send your GSC back and we will re-program at no additional charge. *Shipping charges apply.
- Install with ease and very little effort.
