    Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"

    Too late bud, I already called him out on the boulders, 25 mph tops......
    This is my trike. There are many like it but this one is mine. My trike is my best friend, and it is my life. I must master it as I must master myself. My trike without me is useless. Without my trike, I am useless. I must ride my trike true. My trike and I know that what counts is not the amount of miles we ride, but the time we ride together. My trike is human in it's own ways, therefore I will learn it as my brother. I will learn it's weaknesses, it's strengths, it's parts, and it's soul.

    And at least we know his suspension can handle that speed.....

    I'd say try and find a tri-z or 250r frame and work with that.

    i cant wait ,we need video of the test drive ,.it does seem like a suspended trike frame to start wuold be better , but if you hit the golf course in the rain you might survive!! GOOD LUCK !!

    I say build it!!! If you have the parts why not. Throw some paddles on it and take it to the sand drags. Anyone ever seen those old conversion hard tail frames from the 70's?

    Just because the idea of a large motor in a short frame with no suspension is kinda far fetched, don't mean it may not work. Because it maybe it will. Who really knows for sure until it's done. Just don't let the haters kill your idea. But make sure it's safe and the BRAKES work.

    This is my trike.
    There are many like it, but this one is mine.
    My trike is my best friend.
    It is my life. I must master it, as I must master my life.
    Without me my trike is useless.
    Without my trike, I am useless.
    I must roost faster than my enemy who is trying to beat me to the finish.
    I must beat him before he beats me.
    Before God I swear this creed.
    My trike and myself are defenders of track.
    We are the masters of keeping quads the losers.
    So be it ... until there is no quad left.

    i looked at different frames this can only be pulled off with a hardtail because the end of the jack shaft with the spocket has to be above the rear end i was thinking about puting paddles on the back and a ski on the front
