76 CR125GP big bore kit

[Husky1]

Building up a 76 CR125GP mainly for nostalgic reasons and not to race at this point. Can any person point me in the right direction for a big bore kit for these bike? Seem to recall a 175GP piston and cylinder can be used. Thankyou.

My limited understanding would be a 175 enduro barrel and head / piston bolt on. Never herd of a GP 175 kit but I do like the sound of it. Not sure if it would be much chop up against a real GP 250 like a KTM thou

Thanks Slakewell, found something about a spacer plate kit fitted with GP175 piston by George of uptite husqvarna US.

Probably would go well in the 125 class until you got caught.

Someone once told me that the only thing more heavier than his EX wife was a 125 Husky.


I do own own a Husky as well.

Maybe, but thought they were pretty good jiggers to run in 76 along with a 360 in the open class.

I rode one recently. It had no set up at all and was basically original. It went pretty good, not RM125B good but not too far off. Handled nice & certainly didn't fell heavy. With some set up & race prep, I think they would be ok. Surely different at least.

Thanks Michael, I figure you don't see many around and those that were, have often been made into a 250 or 390, so it is worth doing. Will call to see you for a few bits soon.

I have one in pieces.

Check the stroke Husky1. I'm not sure what GP175 model yr referring to but in 76 the 175 Huskies I'm familiar with (CC model) had 57mm stroke & were based on the 250 engine while the 125s had 52mm stroke.

Earlier '175' Huskies (they weren't full 175s) had 52mm stroke & bolted onto 125 engine, but I think you'll find they were slow
