REVERSE TRIKE Using 600 CC Yamaha
This is a Reverse Trike(RT) that I designed and built a couple of years back. It took around a year to design and build.
I wanted to have a RT with the back leaning like a bike, and the front square on the ground, like a car. So I devised a hinge system that would connect the front and the back together. That part worked well.
But the bike was nearly impossible to control around the turns. It would get flung to the outside of the turn and no matter what I did would not lean into the turn.
I have dismantled the RT since then. Gave the motorcycle to a Philippino friend who helped me out with parts when I was building it, and have kept the Quad Bike parts of the front for the future projects.
I post this so that if you’re thinking about building a RT, you’ll know what doesn’t work and go a different route, or at least don’t do exactly as I did.
Good luck with your projects.

Unstable because tilt of bike turns steering mechanism / rack. You are tilting and steering on the same axis. 2 push pull cables and it will work fine. A bit more work, use 2 arms.
When I had steering wobble issues, I corrected them with a hydraulic steering stabilizer/ dampener. It worked 100% (this is with a revived wrecked 1985 Yamaha Rz350 which was stock configuration without any 3-wheel additions)

Hey hold your horses; drunks are awesome so long as they have access to a grinder, mig, bender, and some tube. Give them some weed and it's Krylon time too.
Hey the reason I can do these projects is because I have no neighbours. Otherwise I'd be siting around with them drinking bear all day (-:
Why can't you? You don't have to build a bad ass three wheeler like the Can Am.
There are a lot of great examples on the internet that are home made and on a budget. I think, well I know for me, building something is a hell of a lot more satisfying tha going out and buying it
Gracias!
Saeid before you scrap the project altogether If It was mine I would try altering the camber of the front wheels ,a little at a time.It may or may not help,but fundementally the Idea is there.regards Bill
Hi Bill. Unfortunately I was too busy with other projects to mess with this Trike any more. THe front end is with me. But I gave the bike away to a friend. May be another time I'll start another RT project. But this time I'll make it non-leaning just to keep life simpler.

The solution watch?v=4J-Y_cR4Iog
Have a look at the Piaggio MP3 trike. they spent a fortune on R&D perfecting what you tried alone. You made a really good attempt with limited resourses.
The only reason it failed was that you didn't reinforce the chassis for the new front end. If you look at it from the top end you will see that it looks like a "T" it should look more like a triangale more than anything. since the way you built it the whole chassis in the front end wants to flex! the shock asorbers don't help with anything, but to stabilize the flex that you have. Try building a new chassis or making some chassis braces for it and see what happens.
Did you ever try locking the steering mechanism so that when you leaned the wheels didn't turn at all? I am wondering if this might be what created the problems. It seems that when others do this the wheels are locked so that they don't turn right to left. It's the leaning alone that creates the turning.
OH, the shape of the tires could have been part of it too. Because the tires are flat bottomed instead of curved like a normal moto tire.
im dying to do a reverse build to my nighthawk cb750, love the bike so much, also liked my R1 which was a beast and would look cool too.
It's those tires. Same reason a quad is shaky on the road.
congratulations for finishing, I never seem to.
Great effort! Very impresive. Maybe make a 4 wheeler or put some fat skis on front for winter and a huge knobbie on back. That's too much work to let go completely.
Have you thought about taking out the yellow shocks, putting in a solid bar and make it a non-leaning set up??
seems like this will work if. you add a steering stabilizer, you change the front tires to something for street use, you brace and triangulate the front end. Use rod ends or heim joints connecting the front most piece on the lower frame to the top bikes frame in between the handlebars, and those joints should allow you motion while also providing rigidity. i'd also check the alignment of the front tires, make sure they are straight, i'd also balanced all the wheels/
are those springs under tension? or are they loose in their unloaded position? as in the one with you off the bike?
too narrow and leans too much…. needs to be "stiffer" and wider.
Thank you for the heads up!! I was wondering… You know!
Hey are u willing to sell it
your links are too long
very good idea
