I'm going to be trying to build a crazy custom frame Honda Hobbit. Inspired a ton by Joe S's Honda Hobbit, as well as Craig Dueck's Motobecane, I wanted to build a chain drive hobbit that sits within a double cradle frame. I've always loved the small 70s Honda motorcycles, but also really want the ease of a CVT for puttering around the city. As such I designed something along the lines of the old VanTech race frames.
Here's the general design
The engine will be bracketed to sit right next to the final drive. I'll need to extend the output shaft a little, but will be going to a Puch rear wheel. I know that I can attach the sprocket to the Hobbit rear wheel, but the whole engine would have to be off center to make it line up with the rear sprocket.
I forgot to snap a picture of the mockup for the brackets, but here's the lineup I'm thinking for the engine:
Essentially my goal is for the frame to function as a kit frame, and I can toss most small engines in there. I'll be treating the Hobbit engine + final drive as a single unit: Cyliner+crank+transmission that just gets bolted in
Front end will be from a KX80.
Frame will be 7/8" chromoly tubing. Was considering 3/4" but the machinist I'm working with strongly suggested 7/8" if I want it to be a daily rider.
I'd love any advice you guys have!!
