    Not a mini buggy,,, but still fun


    77 Harley Sportster bike to trike conversion

    Independent rear suspension, RPM reverse gear box showing up next week.
    This is stock bike mount.
    We are going to customize the frame and drop the seat and put forward controls on it.
    So it rides like a "Big Wheels"

    Just a note. If you plan on making it street legal you cannot use the RPM tranny. There is SUPPOSED to be a diff in the drive axle. At least in Michigan. Better spring for the Jeffco.

    EDIT: I DO realize a jeffco will not fit in that current rear end assembly.
    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Lets hope the next guy repeals NObama care along with the rest of the stupid crap this blight on our windshield has done.

    yup, I'm aware there is supposed to be a diff. in Michigan

    unlike making our new build buggies street legal, The bike already is already titled and street legal
    was told by customer the registration does not change because trikes are still motorcycles so they should not need to even get inspections
    Others say that with their insurance companies, the trike kit is listed as an add on accessory and they only increase their insurance for the added value

    and then there are so many people who call all rear ends ,,, rear differential. Not realizing the difference between limited slip and a spool / locked axle
    if ever needed, hopefully they just point to the gear box and say thats the diff and the person asking does not know the DIFFerence

    I know the people think its legal but I will tell you if the guy is ever in a wreck a lawyer will OWN them. Hook line and sinker.

    Like many who drive illegal things due to a loophole. Its Ok till they get caught. Once caught it does not matter.

    Those with machines on the street that cops let go because the cops did not know are still personally liable in a court of law. They can try to blame the cop who let it go but I will tell you this will fall on deaf ears in court. Just because a cop OKed it does not make it legal. Believe you that.

    The only way I would drive a non diff vehicle is if it was thru a business that was thru an INC. Then I would only loose the business but not my home and bank accounts (maybe)

    I would not do it by choice.

    you could pull an axle off and call it a side car although I have seen side cars with a drive axle that comes foo the rear wheel, now I'm just confused.

    I have done a TON of research (ton more research that is)
    talked to bikers and trike owners, looked up other trike manufacturers , looked into michigan and Federal law.....lots of hours

    Many trikes are a locked axle and have been around for a long time, including ones made by other manufacturers
    some trikes drive with one wheel and the other is free wheeling , some with a dead axle free spinning on one side, this would be an option on the rpm gear box conversion but I do not plan on doing it
    some trikes are open diff, some LSD

    as far as I can find thru much research the law for a limited slip differential requirement is for 4 wheel vehicles in Michigan and does not apply to bikes and trikes
    so a locked rear on a trike is street legal

    performance wise not arguing an open diff or LSD with a straight axle will turn without squealing tires in a parking lot


    research also shows if a posi or locked rear end,,,independent rear suspension with a locked rear handles much better than a straight axle with a locked rear end

    not a trike but I ran my 2 seat buggy with RPM gear box on asphalt road courses and it handled great,,, even in the parking lot

    I am sure Nutz will puts many hours in to find where they are illegal,,,,, but I could not find that result over the past couple of days
