The V-Max and the SRX are two totally different sleds. I think they only thing that is interchangable is the rear suspension. The engines are COMPLETELY different. Blocks are different, V-Max is a single carb, single pipe engine, SRX has three carbs and three pipes.... has about 30-35 horsepower more then the V-max. Both sleds ride pretty good, the SRX handles probably a little better then the V-max.
