TON PELS SIGNATURE SERIES CURVED RIGHT SIDE DRIVE SWINGARM KITS FOR SOFTAIL

The Fat Tube RSD frame is designed to accommodate for the latest extreme wide rear tires, such as Avon’s 300 and 330. Frame accepts stock and aftermarket Evolution style Big Twin engines, when used in conjunction with ZPN236889 motor mount adapter it will also accept a Twin CamA style engine. Must be used with Right Side Drive transmission. The Right Side Drive frame allows for central mounting of the 330 tire in the frame and keeping a perfect balance in the bike. The frame features massive 35mm down tubes and 28mm swing arm tube size. In addition we increased the frame side plate thickness from 12 into 15mm, providing Fat looks that are in balance with the wide rear tire. These side plates are stepped at the seat mounting area, allowing the use of an Evolution Softail style seat, such as our Le Pera Bare Bone seat. Frame takes up to 12 1/2″ wide RSD rear fenders. The steering head is raked to 38 degrees, this requires a 4″ to 6″ overstock fork (depending on the front wheel and tire size used). Mounts for side stand and forward controls are welded in place. The frame also features a Twin Cam style oil drain system. Frame is fully TIG welded for superior strength and takes 1987 thru 1999 Softail style shock absorbers, Evolution Big Twin oil tank, Flat Side gas tank, Evolution Softail style forward controls, Big Twin style steering head bearing cups, and Custom rear brake calipers with Y-bracket.

We have created a Sportster frame with the same sleek design as our Wide Tail Softail frame. The Sportail frame features a « Stretched Low-Rider » look, is made from thick wall quality tubing and TIG-welded for improved strength and road holding without disturbing the lines. To obtain the sleek stretched Low-Rider look the steering head is raked to 38 degrees. This requires a 4″ to 8″ overstock fork depending on the wheel and tire size used. The engine is located with no offset in the frame and a rear frame section wide enough to accept extra wide tires. There are two Sportail kits available, the Sportail WideAss, designed to take up to 200 tires, and the Sportail SuperAss, which is wide enough to take up to 250 wide rear tires. Both kits still work in combination with final belt drive. The SuperAss requires an off-set front pulley or a spacer behind the front pulley. Pulley cover requires spacing. The length of the frame requires the use of a drive belt with approx. 135 teeth. Mounts for a Big Twin side stand and Big Twin forward controls as well as 1974 to present Sportster forward controls are welded in place. Stock style Narrow or Wide Glide forks as well as our state-of-the-art Ceriani forks can be used with the frame, it will also accept many other Custom front forks. The frame will take any 1974 thru 1985 Ironhead Sportster engines as well as 4 Speed and 1986 thru 2003 style 5 Speed Evolution Sportster engines. Because of the right hand final drive the stock style Softail oil tank does not fit, therefore our special Sportail style oil tank or a custom made oil tank such as our Custom Round oil tank must be used. The frame is designed to take Softail type parts and accessories such as Flat Side tanks, forward controls, seats and 1989 thru 1999 Softail shock absorbers. Due to the completely different shape of the swingarm a Rigid Frame type rear caliper kit must be used. 1989 thru 1999 Softail shock absorbers can be found elsewhere in this section.
Note: Zodiac Sportail frames are TÜV approved as a replacement frame for Harley-Davidson Sportster motorcycles. They may be used in combination with our TÜV approved GCB front forks and/or any other TÜV approved components.

The almost unlimited growth of rear tire width has driven the Custom Bike Builders to the outer limits of offsetting primary drives in existing frames. Our 55mm primary offset kit is really the limit of what is possible, extending the main shaft further will put too much torsion stress on the shaft, the 330 tire really needs a different approach. We strongly feel that instead of offsetting the primary to the extreme, it is better to leave the primary in the original position and move the final drive over to the right side. Zodiac developed a swing arm and transmission conversion kit that allows the use of a 300 or 330 wide rear tire in a stock Evolution or Twin Cam Softail frame. We offer two very cost-effective solutions, one with a RSD conversion kit, that re-uses as many stock parts as possible, and one with a RSD builder’s kit. The RSD transmission conversion kit only includes the parts that are needed to convert your stock transmission into a RSD transmission. It includes parts such as: main shaft, counter shaft, shift drum, shift forks, etc. It also includes a new Billet trap door that gives room for the main drive gear. To avoid any « not wanted » load on the cast transmission housing, we have designed the trapdoor in such a way it is not only supported by the lower frame tube but also by de swing arm pivot. To make the internals of transmission stronger, the fifth gear countershaft has become an integrated part of the countershaft. We have completed the kit with the required hardware, new seals and gaskets. Some builders may not want to use their old transmission gears, for those we have a complete builders kit available. Builder’s kits have the gears and shafts installed on the trap door, and include all internal parts of the transmission. You can use these in your own or new transmission housing. All RSD conversion and builders kits use a special RSD clutch actuator/pulley cover, which is separately available. Clutch actuators are available in hydraulic or cable operated. The cable operated clutch actuator works with stock Big Twin clutch cable, the hydraulic operated clutch actuator requires an 11/16″ bore master cylinder. We have OEM style and Custom Style clutch master cylinders available, check out our Handlebar Controls section. Kits for up to 300 series rear tire include RSD transmission conversion or builders kit, TIG welded swing arm, stainless steel swing arm splashguard, and rear wheel axle. Kits for up to 330 series rear tire also include an offset final drive front pulley, extended clutch pushrod and a spacer ring for the clutch actuator/pulley cover. For those that prefer to use a wide wheel with 1″ bearing we have bearing sleeves ZPN735416 and ZPN735417 available. A raw steel RSD belt guard is available separately.

Note: Installation in Softail « Deuce » models requires some modification of the frame and swing arm.
