BAKER Drivetrain | The Drivetrain Authority - XL6 Six-Speed Overdrive Conversion Kit 91-94 Harley-Davidson Sportster & Buell Motorcycle

The BAKER™ XL6 is a six-speed overdrive ‘cartridge style’ gearset that converts any existing 1991-2003 Sportster/Buell to a BAKER™ six speed. 2nd through 5th gear ratios are effectively the same as stock, 6th gear is a true overdrive. Stock gear widths in 1st through 5th were retained and a beefy 6th gear was added. This was accomplished by utilizing an exclusive BAKER dog tooth design that is an industry first for American motorcycles. OVER a 500 RPM drop in top-gear cruising RPM at 75 MPH REDUCED vibration. IMPROVED fuel economy. REDUCED wear and tear on your engine. SMOOTHER shifting and improved neutral finding.
