 Wide Rear Swing Arm Kits
For Harley Davidson Motorcycles & American Custom Bikes

PLEASE NOTE: This is not a project for the novice do-it-yourselfer. This is a difficult conversion, and should only be handled by experienced mechanics. If you do not have experience enough to tear apart and rebuild your transmission, we suggest you take it to a professional. All parts should be mocked up before finishing (i.e. paint, powdercoat, chrome). THESE PARTS FIT APPLICATIONS AS LISTED.

NEW! Convert to 280/300 and add a 6-speed RSD Transmission! Baker 280/300 WIde Tire conversion swingarm kit includes Baker 6 speed Right Side Drive Tranny!

As we all witnessed, virtually every custom motorcycle that catches your eye, whether it be on the street or in a magazine, they all have one feature that is nearly universal; that is they all have a wide rear tire. With this recent phenomena, the wide tire has seemingly become a design standard, this can be seen more than ever since the release of the Avon 300. With the use of these monster tires comes the necessity for a right side drive transmission, which is exclusively offered through BAKER Drivetrain. These two products have since prompted quite a stir throughout the industry and have begun to dramatically transform what is possible with custom motorcycles. Now, using this momentum BAKER Drivetrain has created to ultimate customization, The BAKER 300, which will converge these two revolutionary design concepts into one harmonious, complete, package. The package will allow for anyone who wants to stay with a production bike to become a part of the Right Side Drive/Wide Tire Revolution. Debuting at Sturgis in August, Baker's newest endeavor will take the motorcycle industry by storm, by converting the ordinary Harley-Davidson Softail into a completely custom street ripping wide tire machine and do so through bolt on changes.

This design and concept is exclusive to BAKER Drivetrain, this is a not a copy or imitation. Within the BAKER 300 Wide Tire Kit, we will provide all of the structural, aesthetic, and drivetrain components needed to perform the wide tire conversion for under $7g's. As you would expect, per BAKER tradition, the entire package will be the perfect blend of form and function yielding a product superior to anything on the marketplace, creating a totally unique Harley-Davidson. To save the best for last, Baker will also debut our new premium Right Side Drive Direct Drive 6 speed transmission as the heart of the BAKER 300 Wide Tire Kit.

Included in kit: RSD Transmission, pulley, mechanical actuator, swingarm, axle, wheel spacers, rear fender, rear brake bracket (please note that bracket does not fit OEM caliper), list of required components that are not included, hardware, axle cover.
