Which one goes faster ? What is the top speed?

 

The Eiger hands down. The 400 big Bear is a pure utility machine greared to work. It will do 45 mph and not sound happy doing it for long. The Eiger will do 50 mph smoothly all day long.

 

These are the wrong machines if you're worried about how quick it is. But the Eiger 400 5 speed will top out right at 60 stock and will be alright doing that all day long. The automatic version is sorta junk in my opinion, and the performance really stinks because of it.

But I really would love to have one of the new big bears. I can't attest for the top speed or performance of the bear because I don't have much experience with them, but looking at the numbers, i think it would be a damn nice machine to have for the price. And knowing that they are still based off the old reliable yfm engine that yamaha has been using since the 80's, it'll probably be a bulletproof reliable, versatile, and snappy machine.

 

My unk has a 07 big bear his top's out high 40z low 50z but has ton's of power id say get the bear the new models have --IRS-SPEDOMETER'S DIFF LOCK AND A FIRST GEAR THAT COULD PULL A TREE OUT OF THE GROUND PLUS THE COME FACTORY WITH ITP MUD LITES -------------------------ALL OF WHICH THE EIGER DOESNT HAVE CEPT THE SPEDO SOOO look into the bear before you pic the eiger as ive said i have seat time on both and its a no brainer..

 

I just remembered that this month's QUAD Magazine has a good shootout between a bunch of the 400 class 4x4's. So before you make any choices, i'd highly recommend that you pick that up and read what it has to say. The big bear isn't in the shootout, but the grizzly 400 is, which is basically the automatic version of the big bear.

 

No a 400 Grizzly will is also much faster than a Big Bear. I had a 350 Big Bear ,the 400 BB is the same gearing just that the motor is punched out and my 350 did 40 MPH and screamed doing it . The Eiger has a low range option so it can work also,but once in High range it will cruise a much faster speeds with more comfort.

Here is a owner,s opinion on his 400 Big Bear

One thing to keep in mind here though is that the big bear has a big market with mud riders. With the gearing being so low from the factory, and all the torque the yfm engine has, that thing will be able to pull some real tall tires and then the gearing won't be so ridiculously low. My buddy has an eiger with 28's and with the tall gearing it's such a dog now. Just something to keep in mind.

 

Defiantly a 400 BB is much better for doing certain things,and mudding with larger tires is one of them,also towing (Less down shifts needed going up long hills).

 

Big Bear!!!! But your question asks which one is faster... Check out the sport quads if that's what you're looking for.
