I was looking for a Tadpole project to make something similar. I wanted it to run on the freeway around here to commute with to a new job i may be starting the first of April. I can easily drive my TDI Beetle but once the weather turns nice around here I wanted to get this going. I figured if Sendler can get 95mpg with his CBR then I could get that or more with a Tadpole project using the CBR as a power plant and the front half of an ATV for the front end/suspension. Then use some coroplast and make a Vetter fairing for it. I came across this one from western Oregon and thought it was pretty neat. The guy somehow used motorcycle wheels. I just can't figure out how he managed the front hubs to make it all work strong enough for hwy use... any ideas?
