Will installing a full set of Holeshot ATR tires on a Prairie 650 or 700 correct the front-end dive problem without progressive suspension?

 

The ATRs helped a great deal but you still will need the Progressive springs- costs about $110 on ebay.

 

they will rid a little bit firmer and handle much better. The Dunlops tend to roll under and this is some of the dive. The ATR's grab better so be carefull. I gassed it in a turn that the Dunlop rears would slide and the ATR's hooked up and into a tree I went. I run 4 psi rear and 4.5 front.
I have the Elka springs. They are a progressive setup. The Progressives are not. They are just a plain 600 pound spring. Both are an improvment over stock.
