Important Note: Raked out front fork with lots of trail generally provides good straight line stability but often result in heavy steering. Engineers at Yamaha will not sacrifice handling for styling, so they have developed a 6 degree "yoke offset" angle combined with the 34 degree steering head for a total fork angle of 40 degrees. The Raider provides light "athletic handling and easy steering" not commonly found on a custom styled bike with significant rake.
