I'm running a 146x2.5 challenger extreme. I'm running 20/42 gearing which works out to a 2.1 gear ratio. I'd say run this, or even a numerically higher gear ratio.

What track did you have before? I have the 2" on mine and a Pro RMK front end. Very impressed with it, but considering going to the 146"x 2.5" Challenger Extreme this year. Wondering if you noticed a big improvement (aside from blowing the belt).

I had the 1.38 cobra before. With the stock front end 42" I switched to 38" zbroz and this track is a huge difference just riding in the U.P.

I'm running the 2.4 x 146 with the pro RMK 2.86 drivers and pro Rmk gearing. Bombed around the fields and runs great, still waiting here I'm in NH for some real snow to test it out, but if it works for the Pro it will work for the SBA. Worked fine when I had the 2" on it.

Anyone run this set up at elevation? As a flatland poser riding the U.P. we're only about 1200'. We have a trip scheduled for West Yellowstone and I was just going to go with the clutching for the 2.0 track listed in the owners manual if anybody has any other tips tricks or secrets they like to share would be great.

I'm a poser ..a troll even. I ran 20x42 with a 2.25.. I run the stock 23/39 in Michigan .. you gotta have something else going on to not turn it here..

I'm going to start with get rid of the can and go from there ..just an assumption
Grab a new belt and some 66s with a Black/Green and lose some helix 58/42 but up to Red/black ..
