We’ve covered a lot of motorcycle powered cars on The Kneeslider and one of the questions we often get is “what do you do for reverse?” Some builders go with a ready made unit, most of which are a bit pricey, while other guys engineer their own method, lots of variations, there. Jack Fleming, over at Roadstercycle, was having the same issue as everyone else and finally decided to get a major race transmission builder to produce a solution that was small, lightweight (just over 15 pounds) and able to handle up to 500 horsepower. Jack gave them the specs and here’s the unit he got back.
6.750 long x 5.1 in diameter, length is 12″ without couplers and 13.25 with couplers.
Just over 15 lbs. without couplers.
1.375 x 10 tooth spline shafts.
4 mounting holes on the bottom
Comes complete with a shift lever.
You can have one for $1050 plus shipping.
It looks pretty beefy as well as compact so if you’re thinking of dropping that Hayabusa engine into a car body of some sort, you might want to check this out.
