imagine the possibilities when the compact transmissions are available on the aftermarket from Baker Drivetrain and others!

Would the V-Rod tranmission internals in a custom machined trans. box work with the big twin?

I understand your reasoning.

While large volume manufacturing is dominated by piece-cost concerns the smaller scale operations such as your own are usually, and understandably, ham-strung by the lack of investment capital (for specific tooling, etc.). I guess that will be a problem for you when seeking to develop your own gearbox. But with what you have achieved so far I think that you will get there one way or another.

I’ll follow your progress with interest !

Thanks Gordy.
The main reason I used the standard primary and gear box was because it was available and something that people could relate to. Something that could be serviced by any dealer. At some point I would like to offer a shorter powerplant, maybe my own transmission and primary assembly.

Good luck Curt, I wish you well.

(If you have not done so already, take a look at Ecosse, Confederate and American Cafe Racers for ideas on how to solve the short gearbox challenge).

Todd.
If the 50 hp bike that you take on these rides is able to keep up with your friends on sport bikes, then would it be safe to assume that high reving high horse power multy cylinder sport bikes are overkill and less affective on the backroads that most of our riding is done on. A smooth power delivery and a wide controlable powerband is much more user friendly and doesn’t require constent shifting to keep the motor happy. Keep in mind that most all sport bikes are designed to turn quick track times, that doesn’t mean their the best backroad bike or the best sport touring bike. In order to have the best backroad bike you would typicly want a broad smooth reving torquey power band, thats why you see so many people stuffing big v-twin motors in good handling sport bike chassis, it just makes sence.
