Converting a single shock CR 500 into a twin shocker

[crabman]

In have been considering converting a single shock front disc brake into a twin shocker, with a leading shoe front brake with a metal tank. I intend to remove the single shock mountings, add a set of fox shocks at the rear, use a set of yellow Simons on the front with a dual leading shoe for front breaks.In addition I intend to respray a similar profile Husky tank to the 78 Honda tank. I would look to create a CR 500 equivalent of a 1978 CR 250
Any thoughts, negative or positive greatly welcomed, suggestions, referrals, ideas all welcome.
I am aware of as similar project that was successfully completed in the UK. I accept that this project maybe referred to as a frankenstein time project, only consolation it will be a gem when finnished.
aLL PHOTOS WELCOME.
Many thanks

there a few bikes like this that have been featured in VMX magazine and Classic Drit Bike magazine.

i personally am not in favour of doing this and then being allowed to race these in older twin shock classes.

but yes you would get a good bike with a good rigid rear end.

would be a good ride but im not a fan of butchering up good evo bikes to make the ridable in older classes keep it as it is i recon buut iys up to you

Not into it. Seems a shame to do that sort of thing.

Hi Zorroz
Please tell me more about that Honda especially the ali swingarm.
What forks are on the front?
Thanks

The front end looks like a cr250/480 83. Is this not a dutch bike? I seem to remember a thread on this in the past.

[caps 999]

yeh i think i remember the same thread

in the other thread it mentions that the forks are yamaha YZ 250 which is what i thought. the machining/shape up the top of the sliders looks oh so close to some yamaha XT/TT 600 forks of the same period.

good idea, that single shock and linkages is just unnecessary weight. 

Anyway I am converting twin shock XL500 to monoshock with twin Fox Shox and Yamaha swingarm at the moment, why should KSI have all the fun. viva the sepcial builders.

You have to be sepcial people
