Uncle al-Is 50mph the fastest your rubicon will go or the fastest you have taken it?I have had mine reading over 55 mph now that it is broken in.I agree fully with you about the rubicon having a lot of torque as mine pulls like a tractor.

Best I' ve done is 49 MPH on a flat gravel road.
Dealer said it will improve a little when it' s broke in.
Damn Thing sure can pull.

Artic Cat 400 and it will do over 45 mph ,I usually run it about thirty if I' m going someplace though . They get to squirrely to run them any faster on gravel .

I own a 92 Polaris and have been over 60mph many times. A friend of mine owned a Su-sucky 500 late 80s I think, 2 stroke he as been clocked at 80+. Another friend owned a honda 250r 3 wheeler which was clocked at over 70+ His brother bought it off of him and did alot of work on the engine gearing etc... He uses it for ice racing and has been clocked at over 100+

There are kits for just about every machine out there that will improve performance it just depends on how much $$$$$ you' re willing to dish out.

1998 HONDA 450 ES,52 mph...once just to see what she would do! Now the slower I go the more I like it...

Yamaha Big Bear. Had it near 40-45 once. But mine is off road and in timber 99 44/10% of the time. All my hunting is done at home, and it' s a farm vehicle when not huinting.

2000 Honda 450ES. 50 miles an hour with the tires full and down hill. 46-47 cruising speed. I live on dirt roads and will take the Honda very occasionally on a little spin. I went last night for work to use it on an inspection. Held the throttle down, and went approximately 11 miles there, and then back, basically full speed. Runs like a champ and slides around the corners nice.

I' ll let you know on my new 2003 Rancher ES 2x4, after it' s broke in.
