What's faster Foreman or Rubicon

My '06 Foreman had less than 100 miles on it,completely stock.I raced a guy on his '03 Rubicon and he outweighs me by 60 lbs.I thought I would clearly win,I was Wrong! Wide open in fifth gear I could get to 56 mph,he was ahead of me by a couple bike lengths and I couldn't catch him.

I can't ever remember getting my Rubicon over 45.

you have a problem with yours.....

I don't think the Rubicon will out pull the foreman and I know a Foreman isn't has fast has a Rubicon.

it all depends on tire size and weight. I have also heard that with a snorkeled bike you can go as fast because of the air passing by the snorkel opening. i dont know...sounds reasonable?!?!

Older Rubicons were true 500cc motors. The new foremans and Rubicons are actually 475cc motors.

The Rubicons are 499cc, even the new ones. At least according to Honda's website

This isn't true. Rubicons were alway 499cc motors. However, Foremans changed form 433 cc to 475 cc.

Although I have never raced a rubicon I have tried one out seems to have a lot more snap to it then the foreman. could be the tranny and the liquid cooled engine. I would have one but still scared of that tranny.

Ok. I apologize. I was under the impression it was the same motor, but more options.

I would be interested to know the reasoning behind extra 24cc's in the rubicon over the foreman. Is the cylinder bore actually bigger? Are they trying to make up for lost power from the trany?

No need to apologize. Honest mistake.... I make my share too.

The bore is the same on both, but the stroke is shorter on the foreman. I don't know why Honda engineers did this for sure, but I suspect that the transmission on the Rubicon isn't as efficient as the Foreman's gears so to try and make up the difference by increasing the engine torque. However, I believe that the foreman still as more bottom end and they could have put a 525cc engine in the Rubicon to equal the power of the Foreman.
However, this lack of efficiency seems to be less noticeable at the top end on the Rubicon.

i say the foreman is faster im raced my share of 2005-up rubicon... and there hasnt been on stock one agaist my stock foreman that has beat me.... now rincon will walk away from me..

I've raced an 02' Rubicon (499cc) and I beat it easy. I also raced our Rincon and didn't loose by more than 2-3 lengths. It didn't start pulling until I was in 3rd gear or so.

However, I raced the POS 660 Grizzly on just 27's and beat it both from a dead stop and a 3rd gear roll. 660's were the worst bikes ever made by Yamaha in my opinion.

when u raced the rincon. was it just a straight line... cuz if not.. i dont see how he beat u by 2-3 lenghts. i raced a 650 rincon. for bout 2 miles. and he beat me by a say 4-5 lenghts.

I raced it in a straight line. And it's an EFI 680. It's had 25" tires and mine has 26" tires. My bike slowed down alot once I hit 3rd and the Rinny slowed down when it hit about midway through second. He just slowed down a little less than I did.


I would still rather have the rincon over the Foreman for everyday trailriding. Rides like a caddy.

ya.. i say i could keep up with a 650 rincon. if i didnt have clutch probs

My nephew has a 500 foreman and I can't keep up with him on my Rubi, though I am 46 and get a little unnerved when that speedometer hits 60 mph.

Just 2 weeks ago I got a truck stuck in one of my fields and he came down to help me. He hooked up and couldn't budge it. We hooked the Rubi up and it brought the truck out and didn't even slip a tire. We used a long strap and had both quads on solid ground. So I would say no way the foreman can out pull a Rubicon.
