The Doherty 200mm Fat Tire Kit comes complete with all the parts (except the rear tire itself) needed to do a wide-tire conversion on Softail models from 1987 on. This kit is available exclusively through Drag Specialties.

dds are a lot of your Softail customers would like to convert their bikes to the fat-tire look. But the odds are just as good that many of them are intimidated by what looks like a lengthy and expensive undertaking, one that can sometimes involve a long wait for parts, a lot of downtime while the work is being done, and a huge bill when the job is finally completed. So they walk wistfully past the wide-tire bikes they see at rallies and shows, and dream of the day when they can afford to hire a shop to transform their own bikes from mild to wild. Now you can turn those sad faces into happy ones with the new Doherty 200mm Fat Tire kit, a wide-tire conversion that doesn’t require cashing in the kids’ college fund, or waiting for your bike so long that you’re too old to ride it when you finally get it back.
     The Doherty 200mm Fat Tire kit, available exclusively from Drag Specialties, fits Softail models from 1987 on, and comes with just about everything you need to replace the narrow stock Softail rear wheel with a wider wheel. Anyone with mechanical savvy, a few hand tools, some factory pullers, and a shop manual can do the job at home. And it doesn’t require disassembly of the transmission, either.
     The centerpiece of the kit is an 18x5.5 40-spoke rear wheel with a drop-center steel rim and stainless steel spokes. The hub is made of chromed billet aluminum and has a unique offset you can’t get anywhere else. It comes with seals and 2000-and-later bearings already installed. A heavy-duty rear axle and pre-cut axle spacers are also included. The kit comes without a rear tire so you can choose your own to match your front tire.
     Other parts in the kit include custom-made CNC front and rear sprockets. The front sprocket is made of chrome-moly, and has a proprietary offset not available anywhere else in the aftermarket. There’s also a front sprocket seal and spacer, a sprocket nut lock plate, chrome-plated rotor bolts, grade 8 chrome-plated sprocket bolts, and a Superbike-quality O-ring chain. The kit final drive ratio is the same as stock, so there’s no need to recalibrate the speedometer.
     The kit’s rear fender will accept stock or aftermarket seat pan shapes, and will support two people with its internal struts. It comes in two styles, one without a taillight, and the other with a flush-mount LED taillight that incorporates the taillight, brake light, turn signals, and license plate light, and plugs directly into the stock Harley wiring harness. Installing the fender requires cutting the stock fender strut rails off of the frame so the 200mm tire will fit.
     Sometimes it’s the little stuff that can bring a job to a screeching halt, so the Doherty 200mm Fat Tire kit comes with most of it–a chain guard and splash guard, a primary gasket set, fender mounting hardware, a late-model electrical tray, and of course complete instructions. And if you need even more help than that, Doherty Machine offers excellent tech support–just give them a call at 1-800-956-9409.
     All of the major parts in the kit are made in the U.S.A., and all kit parts are pre-fit on a fixture before they’re shipped so there are no nasty surprises when the bike’s all apart on the garage floor. Doherty Machine offers full warranty and tech support on all of its products, and the 200mm Fat Tire kit is no exception.
     Don’t let your Softail customers walk around moping a minute longer. With everything needed to convert a plain old narrow-wheel bike to a fat-tire head-turner except the tire itself, the Doherty 200mm Fat Tire kit can not only turn their dreams into reality, but make your parts department a happy place, too.
