    " I actually think it is good that you have clubs where people can go and enjoy riding these things together. It reminds me of how the prisoners on death row have fun waiting for their turn on the electric chair. Fair enough, the trike isn't an electric chair, but it is about as safe and comfortable as one."

    Sorry...forgot to post the finished product.

    The radiators take extensive modifications to work. Also, NOTHING is stock on this bike.

    Louis, I'm pretty sure Derrick's Z Is 55-1/2", front to rear wheel base. Not sure on the rear width, I do know he runs a wider than stock R axle.

    Those radiators are from a CRF450. But we have complete custom mounts and shrouds and subframe, seat, and gas tank to fit.

    this bike looks more tricked out, user-modified show bike, whereas the other design looked more like something out of a factory.
    i like the new one alot, but something about having a factory-looking new trike was just sweet.

    GREAT WORK MAN!

    Good job...again.

    I kinda agree with 300rman on the looks. I dig the throwback scheme of Yellow/Black. The green/blue is more modern race style and definitely makes it look more custom, but the yellow looked like it was built by yamaha.

    Major props to you though. It's an awesome trike no matter what color it is.

    I think you've made an improvment Derrick.

    Liked the yellow and Black one, Love the engineering, just wasn't fond of the radiator shrouds. I think these latest mods look awsome

    Now let me get this straight. In a nutshell it consists of the following bits:
    Tri-Z frame (highly modified?)
    450R swingarm and rear axle Assy
    Custom Triples
    125cc MX forks (Brand?)
    YZ450F motor and radiator shrouds
    CR450F radiators
    YFZ450 rear subframe seat and rear fenders
    Blue ATC250R front fender, and
    a load of self fabricated bits.

    I'm unsure about the Fuel tank or Rear shock????

    Would that be about right?


    How does it handle with the higher seat height, better or worse?
    My toys 85 KXT250A2, 85 ATC250R, 85 Tri-z 250, 06 LT-R450, 04 YFZ450S, 07 125 typhoon x 3, 06 FPV GT.

    It's running a stock Zinger tank under the custom cover. The rear shock is an 06 450R unit.

    The added seat height had no adverse effects on the machine at all. In fact, it actually improved it. I found that the transition from sitting to standing is less, which actually saves energy and reduces arm pump (when racing). Also, it should be noted that this bike is built specifically for MX and that you really don't spend too much time on top the seat anyhow. When you corner your down off the seat, and the rest of the time you tend to slouch/stand.
