I've been wanting to build a kit car for some time and have been doing some reading on Bike-Engined cars. The !!!error: Indecipherable SUB-paragraph formatting!!! looks to be good inspiration for this type of project, but I can't find much literature about it. Reverse seems to be a big issue with these types of cars, and it looks like they have a good system; they posted pictures of it on their site:

This, along with with a separate lever, operated like a 4WD transfer case; is supposed to reverse the entire gear set. So the car effectively has 6 reverse gears.
I just can't figure out how it works by the photos alone. I would appreciate if someone can explain it to me. Thanks

Motorcycle engines typically don't work so well in cars because of their inherent lack of torque and high-revving nature which is hell on clutches. Not to mention "high miles" for a bike is about a quarter of what is considered high miles on a car engine.

Look at this picture.
The little black knob next to the shifter is the reverse lever, which is connected to the green casing that is the reverser itself.
The reverser connects to the output on the engine transmission, and has two ratios inside of it, a 1:1 for forward rotation and a 1:1 for reverse rotation. All the reverser does is select the reverse rotating ratio.

Look up the Mevabusa. I believe they offer an electric reverse.

I beg to differ-on everything posted.
I've been racing bike powered cars for 15 years. I've had a Yamaha FJ-a Kawi ZX11 and currently a Suzuki GSXR 1000. I haven't had an issue with a clutch in any of them. And I load the car pretty hard—racing it uphill. And theres no reason for a modern FI engine to be worn out at 1/4 car mileage. They are actually very under-stressed in normal use.
The bike engine has the powerplant-clutch and trans all in one unit. Where the front sprocket would be, there is a flange that bolts on-that turns a driveshaft to a conventional rear axle. The forward/reverse box just bolts between the flange+ the driveshaft. So you get 6 speeds in either direction.
A fairly stock 'Busa would give you about 190hp—and 100 lbft of torque. With the motor/clutch+ tranny weighing apx 185lbs.
