Fat Bob Models 2012 on

 … "New engines, new luck and new compensator sprocket assembly"… seems that's what HD must have thought. So as well as fitting the higher capacity 103" engine they also fitted a new compensator sprocket assembly to all models from 2012 on. Which also means that an updated version of our popular & proven offset kit was required.
But we soon overcame this hurdle.
13mm:
A specially cut & hardened gear wheel is included in our advanced kit for fitting to the new compensator sprocket assembly. This enables sufficient room to centrally mount a wide tire up to 240 in width.
And … the bonus is that the gearbox doesn't have to be opened up to fit this kit.
22mm:
With our 22mm Primary Offset Kit we go even further. By the use of a 20mm slim belt as fitted to the Softail, so there are no reliability issues. This provides 9mm of extra space and therefore enough for a 260 tire. Again without having to open up the gearbox. Because the belt is longer this kit will only fit in combination with our "Bigger Swing" swing arm.
63mm:
This is the most comprehensive of our 6 Speed kits. But if you want to implant a 300 tire into your bike you need to make room for it. This kit provides 63mm offset. This is made possible by a newly designed and patented Offset Clutch Hub. The clutch is relocated on the main shaft so it can be retained. The offset gearbox pulley runs on bearings mounted to a support plate allowing for the highest power engines to be used. And … the the gearbox doesn't have to be opened up to fit this kit.
