Typically the stresses are from torque and not necessarily horse power. A slow moving high torque vehicle will kill a tranny by shearing teeth, smashing bearings and various other high pressure senarios even with a low horsepower number. While a high horsepower low torque engine will be unfriendly to trannys by spinning the components so fast that the centrifugal forces (change your reference frame and then try to tell me its not there) will exceed the strength of the rotating components. More infor than was necessary, probably, but meh...peace. Just a note on trany deaths. Typically the stresses are from torque and not necessarily horse power.

I did have it beefed up a little by a dune buggy shop but if I get on it in too high a gear at low RPM, it will slip. Got to keep the revs up. As to a video, there is a clip on my website rotohak.com of an interview that was on the speed channel. I'm just talking about the bike so there is no footage of it going down the road. I can tell you though, I've surprised a few knee dragging crotch rocketeers along Skyline Road near where I live. The thing will do a wheelie at 50 and corners like a Porsche. It is all I can do to hang on going around a corner. I've thought of velcroing my but to the seat to keep from getting flung off. voodoo-chile, as todd said, these trannies are built pretty stout.

In stock applications, sure they're handling only 100 HP but it's also pushing around a 5,000+ LB camper. I think it'll be fine in this application. The front steering looks pretty typical for an outfit (sidecar rig). Nothing unusaul there to give away the secret. -todd -todd voodoo-chile, those VW trannies are usually bolted up in front of a blown chevy V8 in a sand rail.

Sometimes it's easy to forget that they are enthusiasts just like the rest of us. Thanks, Kneeslider.
