I ran a apex mtn for 2 seasons, way back when and the track speed was pretty low as I recall, even after I removed over 100 pounds from the sled ect ect.. try way lower gearing, I ran a 18 top sprocket and it really liked that. Cant remember what the bottom was Maybe 2 bigger than stock.
I was just wanting a comparison my wife's nytro mtx 162 with skinz tunnel dump exhaust and Lincoln county customs clutching turns 35-37mph in deep powder. My buddy rides a 07 skidoo 800 with 151 his track speed was 45 in same snow. Wanting to know what a non turbo apex is turning.
Last weekend, we had about 2 ft of fresh, with about 6 ft under that, not much base, my track speed was really high, dont know exactly, couldnt see through the snow on my speedo, but the sled wasnt moving to fast.lol
