CR80 USD forks on CT 70

[rmhrc630]

Sounds ambitious, Apparently they can be cut down which might mean they would suit the dynamics of the bike. With a plus 4cm swingarm I think this might work.

Anyone already beaten me to the punch and added CR80 USDs to their CT70?

Anyone got any pics of such a conversion?

Stock they are 275mm travel - those in the know think that CTs can do with 125mm travel. So they would need to be cut down.

I just think it might make disk brakes etc easier to fit and I like fitting genuine Honda parts. I once modded my XR600 to USD status and well never stopped tinkering until I had electric start...

I've done alto of research on this, The CR 80 even the KX 65 have to much travel to keep the bike balanced. If you compare the fork rake to a 1981 ct with stock shock length (335mm) fork length around (605mm). So about 630mm (from top to center of axle) fork with 6" travel with a 340mm shock is about max without throwing there balance off or tire to fender clearance. If you extend the swing arm 38mm it only raises the rear end about a 13mm. Not saying you can not shorten the fork ,but it might be easier to source one of like a King Cobra or some bike like that. Also I can get top triple clamps in different diameter and I'm working on longer swing arms. The picture is a 1985 XR 80 fork.

The stock legth on a 1981 CT fork is around 604mm

Thanks greg looks awesome! I think the trick is getting the cr80forks cut down to 125mm travel. The flat track guys do it!

we need to see how the flat track guys do it

I'm sure it could be done, Another fork to look at would be off a KTM 65 that way the over all length would not be to long and you would only have to shorten the travel 2 inches. I like the way your thinking, There's way to have top notch suspension without breaking the bank, Rear shocks is the tough one your looking at least $300 all day long to get something descent.And the vintage CR,KX,ect 80 shock are usually shot and I don't think you can get parts to rebuild them anymore.
