Hi all

I am new to the forum. First a bit about myself. I live in Warwickshire and have done a lot of building and restoration work over the years. I presently have a Triumph Spitfire, Fiat X1/9 and a 1100 Yamaha trike. I have just got another Yamaha 1100 and would like to build a sprint/hill climb trike.




This is the sort of thing I have in mind. I would also like to make it in a way that it can be made road legal. Anyone out there know of anything similar or got experience with racing sidecars. Also any other thoughts or comments.

Regards

Rich

Don't think MSA events permit 3 wheeled vehicles - possible exception for period defined vehicles.

I have seen 3 wheeled Morgans at 'Historic' hillclimbs.
They may be permitted to run at events where there is an ACU permit.

Ask your questions here, I'm sure someone will help.

Hi

Yup we see the bikes at Hillclimbs a few times a year, the classes for them (inc Trikes) are run by the National Hill Climb Association - www.nhca.co.uk, make for good meetings IMHO as the mix of cars and bikes makes a very nice change.

Good luck with the project

Are you looking for a more common outfit (Monkey next to you, 2wheels inline)?
Or something out of the box ?

The picture of the trike you posted looks interesting.

Definitely quite a bit of a Jedi rear end in there (uprights, trailing links, etc., etc.). I wouldn't be suprised to see the whole rear end of the chassis in there as well if you had a side view of the beast.

Nice lightweight way of doing it, simple too.

nice!!

Hi all

Thanks for your comments.




This is a photo showing the front end steering on the trike above. Does anyone have any knowledge, ideas or sugestions on this setup.

The Cog of this machine looks like it is very far from the 'wide' axle.
In sidecars (or any 3wheeled) vehicle the goal is to get the mass as close as possible
to the widest axle.
Look at F1 outfits, moste people argue that a reverse trike is the best option.
I agree, as you have maximum stability and most grip is towards the steered axle.

Hi all


How about





or





at least the 2 wheels are at the back. I must admit this one makes me smile.





My present trike
