1984 Husqvarna 500CR Prototype???? on Ebay

VERY interesting!! Please keep us up to date on what you find, I have a feeling this is a very special Husky. I wish now I had bought it.

does anyone have any pics of the right hand side of the grossi cr500?

hi its stamped in rather than engraved in the place where the frame number would normally be,expo proto,

I think this is the fully restored bike discussed in this thread: http://classicdirtbikerider.com/features-page/1982-works-husky-cr500/

I know this is an older post but my local husky dealer said there was a 500 kit that was offered by Husqvarna to make your 430 bike a 500cc. I'm guessing it came with the longer cylinder studs, crank, cylinder, reeds, manifold and piston. Not sure if it was a 38mm/40mm/44mm carb?

Your local dealer was wrong unless they were talking about the Pro Circuit 470, which was not a kit.

The kit would have needed a long stroke crankshaft if there were ever such a kit, The production 500 uses the 86mm 430 piston for std bore.

production 500 uses its own piston, it just shares the bore size.

82 430 was sold with a free Malcolm Smith desert tank as a late 82/83 sales promotion. I bought this package in early 83.
82.5 500 was sold with the desert tank and a 6-speed trans in a box.
Those are the only "kits," although nothing stopping the guys at the time from picking through the parts fiche and converting to a 500. Makes my wallet hurt just thinking about it.
Justintendo is correct it's a different piston with the same bore.

Thank you, never saw a 500 piston before

I had a 82.5 husky silver streak 500cr to purchase but I was informed that $650 would purchase it but the seller wanted $750. I was a $100 short I passed. Fast forward decades I have one in parts finally. I think I have two 500 cr engines, extra 500 case, two 500 xc/wr engine. So far.
