ATV transmission adaptation

Had some off time to surf around shops and found myself staring at big ATV and it´s engine/transmission.

It was shaft driven and maybe had diffrential in the rearaxle but what was most interesting that automatic clutch & transmission system looked like tight packet. I figured out that by using suitable pulleys etc it could be used as "automatic"transmission as it is.

Had anybody ever tried to use one on dBike?

Haven't actually tried it but I did think that the transmission of a mid 90's 2wd Polaris might have good possibilities for the same reasons.

I also thought that the new artic cat diesel 4 wheeler would be a great donor to the diesel bike complete with calibrated CVT and Lombardini twin..... It will do approximately 40-45MPH on a heavy ATV.... put it in a light Bike and gear it up you would have the starting of a great Bike IMO..

Next time I have some spare time I´ll ask from ATV workshop for tech specs

I´d be quite simple, not easy maybe, to use one. Fiddlind with pulleys for primary and having rest of pack attached to frame and shaft.

Must do some serious math beforehand.

Wouldn't a submarine transmission be a bit big?

Polaris is an american made ATV using a CVT Drive to a High low transmission

New 325€, slightly used 285€. With centr. clutch and reverse.

Beats Comets. If Dnerp gearbox becomes too hard to mate I´ll go for ATV-system and adjust it to work with pulleys or gears.
