I was musing a about bolt on conversion of a basic 125 with as little custom made parts as possible.

A few things I was considering were,

If a quad bike axle unit could fit onto the rear forks or a quad style swing arm.

Building a box section to replace the swingarm then fitting wishbone suspension, perhaps the parts from a small car, onto it but the problems would then be connecting a differential and custom driveshafts. I did think about rear tilt but then it would create drivetrain issues.



Front tilting looks the best but would be a bigger pain to do.
There's the piaggio twin scooter fork setup,or bike forks* like this guy with his suspect choice of music.
Others I've seen do it slightly differently. There was a Norwegian trike and there were some asian blokes doing similar conversions on smaller bikes and scooters.

Any other ideas?

What would you actually do with the finished product?
a 125 with more weight...

I've never seen the point of a trike conversion. You get the worst of all worlds. Weather, lack of filterability, being laughed at, not having both legs, you know the kind of thing.

But three wheelers that face the 'wrong' way. Yes. They really have my interest a lot. Do that. But with a bigger engine than a 125, obviously.

Ride it on a car licence and have less of this

and more of this

and if it doesn't turn out as planned then restore it back to original condition and sell.

So you end up with all the disadvantages of both a car and an bike?

For the love of god, why? Unless you have both legs missing or are quadraspazzed, just don't.

As the owner of a 'car based Reverse Trike' I can assure you that a bike's better if only for the filtering ability.
I rarely use it (may sell if you're interested) as when the weather's good I usually take a bike (9 out of 10 times) and if the weather's crap then I use a car.

If you really want one then get a piaggio thing and see how much you like that.
Bear in mind the width of it and if you decide you really want to make your own then you'll know how wide a trike you can live with.
But with a 125 the additional structure will have to be really light or you'll keep getting overtaken by cyclists.

Why not buy a road legal quad bike? More fun than a trike, can also be driven on a car licence and can go pretty much anywhere.

if you mean one of those tarty things that chavs ride then they are crap off road and no one lets you ridie them at tracks (most have banned them) as they attract the idiots that cant ride a bike

and farm ones tend to be crap on road as they have knobbly tyres and do about 40mph

I'll get my coat now, but I once saw a modified quad at Newtown crossroads in Birmingham. It had wide road tyres on it and a ZZR 1100 engine fitted with hardly any exhaust after the 4-1 collector. The rider looked typical and appropriate with no lid just shades on and one of those bandana things covering most of his face.

Nope definitely not for me, so give me a proper trike instead with a supercharged Rover V8, beer barrel on the back for a fuel tank, and the nitrous bottles strapped behind the seat.

Aren't trikes for people who can't ride a bike too? I had a Polaris Outlaw 500 and it was great off road and insurance wasn't even a quarter of what I'm paying for my bike now but imo its just as pointless on the road as a trike, just offering a possibly cheaper option.

No comparison, just saying it performed well. Not as well as a proper off road quad, dirt bike or 4x4 as you would expect but I don't agree that they are "crap" off road.

It not being as good as any of the alternatives isn't what most people would consider great. Razz

True Sad ...I'll go with "good" not "great" then. Still... not "crap".

I ride a 400cc Yamaha farm quad as a job

It's ace off road in 4x4 mode

In two wheel drive it's fairly good as chunky tyres

It's abysmal on tarmac

A chav quad has two wheel drive and the wrong tyres

They are shit and don't lean so need to power slide round corners

I have had to tow a fair few out of muddy water to know they are shit

You want the Vigillante with a claimed 0-60 in 3 seconds.

If I could use it properly in the right places they look great but they're taxed and priced like a car.


Anyway does anyone know other software apart from solidworks for designing and testing parts and the type of maths and forces likely to be dealt with?

As opposed to a leaning four wheel quad, (most) trikes don't lean, meaning they turn like a normal quad. As above, that basically means if you want to go any decent speed, it'll flip you flip over and crush you!

Oh and... many years ago at Bulldog bash there was some V8 trikes with Nitrous etc. Couldn't even match the standing quarter of my stock J1 ZX6R.
