Review on Spree Compatible Replacement Sportsman 2007 2016 by Vinay Mickel

I bought 1 piece for my 450 and 570 athletes. I wanted something that could be used a few times before I had to replace them. On both quads, the fit was spot on. Then I took them both for a ride, the 450 had a noticeable increase in power. At 570 omg I hit the gas pedal and the front wheels lifted off the ground. Now I don't have a dyno, but now I like the throttle response. If there are flaws in the gems, I can't find them. As for the cost, I don't understand why not everyone has it.
