i'm thinking i'd have to use the forks off a smaller bike because of the height and then the rest of it would be from a quad...
alright i'll get it started...

ok so i've been planning this for a while but never really looked into it... maybe you guys can help a brother out. i was going to make a modern day 3 wheeler using the back half of a quad and the forks off a dirtbike... would look something like this.

what would be the advantage to this type of machine vs 2 or 4 wheels?
if it's just a project for fun, then I suppose it needs no justification, lol.

not sure of any advantages but my dad and i have always been into 3 wheelers... he made this one a long time ago 
and then i used some spare harley parts i had to do a little customizing to my 110...
i just think it would be cool to have a new 3 wheeler that would keep up with modern bikes...

ATC250r. That'll keep up with 99% of quads out there.

true... those are fun and fast but having a 450 in one sounds like fun!

Looks cool but being unsure of how the small front wheel and motorcycle geometry would affect handling, I would do some research. Check patents and SAE papers online for information, I doubt you will find anything out there about 3 wheel vehicle dynamics because they are pretty terrible just by design, so you may need to emulate something that exists and works well.
Too bad I didn't get shotgun on the forum that I asked for! Ha.

Seen someone make a ATC450R (crf450 combined with a trx450r) they used the 3 wheeler front tire though, i dont know how well the dirtbike front tire would handle

how about a motorcycle drive and quad steer setup?
seen that done... the new Can-Am Spyder is like that and it works really well. for offroad though i think having the skinny bike tire on the back wouldn't work for pushing the duel quads up front... not enough traction.

all the "parking meter" cop car thingies here in San Francisco are three wheelers. I wonder why? Less cost to maintain?
I guess you'd get awesome traction with two rear wheels in the sand.

Do some searching on here, a couple guys have already done it. They look pretty bad ass, if you're into that three wheeler thing. I guess they're great in the dunes. Not my thing though.

It would never work on something like a fire road or packed dirt trail. Every time you turn it would want to high side you due to both rear wheels only wanting to go straight. Like suggested the Can-Am design allows you to lean into turns with 2 front tires and independant suspension.
Posted 29 May 2009 - 02:26 PM
A quad front tire would be needed for handling. Also a fairly wide rear axle would be needed for stability.
For the suspension, a good independent rear that was designed more to lean inward to a turn to keep the inside wheel down would be good.

have two front drive tires and one undriven rear tire solves the instability problem just have to get the front half of a 4wheel drive quad and design some sort of transfer case. maybe mount the engine in such a position to even out weight distribution. only downside would be no more wheelies.

I say pickup an old atc250r, drop in a cr500 motor, and be king of the hill for under a couple grand. plus its cool being on an old klunker flying past everybody.

That's probably a reason they got rid of 3-wheelers in the first place in the late 80s 
I remember, my older brothers had a few and we'd raise hell on them.

Seems like this could offer a safety solution if you could work out the traction issue. You would no longer have to worry about a rear tire eating your leg if you put a foot down for any reason.
