    Always wanted a mini bike as a kid, guess my parents were too smart for that, I had 4 wheel toys.

    But now I'm grown and can do what I want.

    Just ordered a 212 hemi predator.
    Got an old TAV2 drive and driven from an old kart.
    Ordered some 20x7- 8 wheels and knobby tires, 12 & 54T sprockets, chain, and brake caliper.

    Have two lathes and a mill, torch, welders, etc, so why not build a custom frame? I'm thinking full suspension. :)

    Welcome....If you poke around this forum enough you will find that you will need to reconsider your gearing. A tire that tall, a TAV2, and that gearing will not be very desirable. At a minimum you would need a 9 tooth on the end of the TAV to go with your 54 out back. 8 tooth is probably what you need. And that's if you want to keep the 54 sprocket. With that tire size and a TAV you should shoot for about a 7/1 ratio for drive and driven sprockets.

    Guess I was overestimating the ratio of the T/C. I'll order a 70 driven and if it's still too tall when it's done then drop to a 10T driver.

    Any guys running solo seats with the springs? How do those compare to a swing arm? Easier to design and build for sure but I don't wanna knock my fillings out either.

    Got the front forks drawn up using some 7/8 ID, 1-1/8OD bronze bushings 7/8 OD stainless tubing, and some 1-1/4 tubing bored to accept the bushings. Going to let the top of the inner stick up through the top with a nice cap nut on top, should look cool anyway.

    Well I ordered a 60T. 72 I think would be just too big. I can drop to a 9T driver if need be.

    First pic is my first rough drawing of a frame. Each square = 2" Second pic is how I'm planning to make my telescopic forks, not to scale.
