whats the fastest you have been on your rancher?
i have been 53mph on my 2x4 ES. i was on pavement,and the engine wassn't warmed up yet. i think i could have got faster if i would have had more room and it was warmed up.

 

I could get mine up to 54mph on my 4x2,when I first got it. That measurement was taken on a paved road on a very,very slight down hill slope. I then too it to the dealer for it first service (oil chg, valve adj, etc...) When I got it back the max speed speed for the quad was 49mph bone stock. Since then I've made some modifications (bigger tires) which has thrown the speedo off by a few mph.

00' rancher 4x2es, 26x12 mudrunners on the rear, 1500lb winch, herculined rack, 55wt back up light

 

156 miles on the quad and now up to 51 top speed. (2001 Rancher FE1)

 

I allways get my 350 rahcher FE up to 53mph, and when im going down hill i have gotten it up to 54, I weigh about 113.
