Top Features
The dual-shock SR 146 offers a long profile version of our acclaimed trail comfort suspension. This lightweight suspension offers premium bump compliance with excellent resistance to bottoming. The dual-load 146 is a 'coupled' skid frame that utilizes a unique sliding front arm mount with half an inch of movement at the front arm slot. This active arm design delivers controlled (reduced) ski-lift during acceleration while retaining a good measure of independent front arm tracking. The addition of passenger 'overload' springs help compensate for the extra weight of a passenger to reduce bottoming and maintain balance.
Performance
Yamaha engineers wanted an engine that's exceptionally quick to respond with little or no 'lag' as found in a conventional turbo. One of the ways they achieved their goal was to develop an intake system using three separate throttle bodies positioned very close to the intake valves, instead of just one feeding long intake tubes. It’s an innovation not seen in any other production turbo on the planet, and another first for Yamaha with the Genesis turbo.
Handling
The effect of four-stroke engine braking when the throttle valves are closed has a significant impact on handling and ride character. Yamaha developed a special system which employs the Idle Speed Control (ISC) Circuit and ECU map using throttle valve movement and RPM information to reduce negative intake pressure during deceleration.
Comfort
The medium smoked polycarbonate windshield was designed to shield the high-mileage rider from the coldest days. The windshield incorporates a small lip at the top to deflect wind and snow up and over the rider at speed, while flared edges provide added protection and warmth for your hands. The GT windshield was also designed to accommodate optional mirrors. The windshield is thicker than standard windshields to reduce mirror vibration at speed and features pre-marked indents for an easy installation of the accessory mirrors.
