The Sportcycle was a 3 wheeler designed by Jim Musser, using a Kawasaki ZRX 1100 as the power source. Actually, it uses almost the entire ZRX 1100, you just remove the forks and connect everything else into the Sportcycle front end. Controls for the throttle, clutch, transmission and rear brake attach to the front assembly. The gauges are transferred to the cockpit. The front looks something like an old Formula racer, you have a single cockpit with seat, steering wheel, pretty much everything a standard open wheel racer would have.
I noticed this one for sale on eBay and according to the listing it’s the original built by Jim Musser as the prototype for the kits that followed. This one has some Muzzy parts and pieces and comes in with 134hp on the dyno. He also fabricated a custom rear end to accept the wider rim and automotive tire.
It looks pretty cool from the front but it seems a little odd from the rear, like a motorcycle rear ended a race car, but handling and performance were probably pretty sweet. Neat.
