New Grizzly, 450 or 550?

I am planning on getting a new quad soon, I have had all kinds of dirt bikes and a few sport quads, and a ATC 200X way back when.
I want to get a quad to drive around in the woods around my house and play in the snow, in a year or two I plan to get my son a quad so I will be riding with him as well.
What kind of performance difference would I see between the 2011 450 and 550? I am not interested in EPS, I have found some info on the new 450 but not much on the 550.
Thanks for any info

You're looking at about 10hp difference for starters.
The 550 is a physically larger ATV; it's the same chassis as the 700.

The 450 has one feature I really like as a mud rider- the sealed wet brake. The 550 has the four-wheel disc brakes which are great for stopping power when they're not caked up with mud or ground down to the backing plates with creek sand.

The physical size difference between the two is pretty significant. I'd worry more about what fits better than performance.
I have a 450 and 700. My wife rides the 450 and it fits here well. That said I actually think I prefer the 450 for the stability, the 700 just feels big, but I guess it just depends on what kind of riding you do. FI was a big selling point for me at first, but the carbureted 450 runs great after I jetted it for the altitude. It actually starts much easier than the FI 700.

I'd say sit on both and see which feels more comfortable. I originally was going to get a 550 for my wife, but when she sat on it she felt it was way too big, which it was.

If you do a lot of tight, technical, twisty wood's trails, the 450 rocks due to its size. Trust me, I know. I've never had an issue with the carb either, mine is jetted right.

It would depend on you're size and how it fits. Me, I'm 5'8" so the 450 fits me great. I've no issues with power either, I ride at 9-12,000 feet and have no problem keeping up with the big bores.

I was just struggling with this decision myself a couple months ago, only for me it was a 450 or 700. I love the features that you can get with the 700 like FI & power steering not to mention the additional power but I ended up gettting the 450. Why? It all came down to physical size for me as all my riding is in tight wooded areas ie: tight trails, switchbacks, bridges etc... & the 550-700 are just to big for these situations. I snooped around on here before I bought mine & seen comments like the 700 has the turning radius of a bus along with the 450 having a turning radius that is best in class. I knew that if I got a 550-700 I would be battling it's size consantly even though all the nice features & power it offers would be missed also, I had to make my decision on the main factor for me...size.
The perfect bike to me would be a FI eps 450 with a touch more power, & starting in 2011 it looks like their starting to give it one of these things.
So all in all if your area will allow for a full size machine like the 550-700 then hands down you should get a 550-700. But if it doesn't & since eps is not a factor for you I would reccomend a leftover 2009 or 2010 450 as there are some great deals to be had right now.

Also, the 450 with eps would be bad ass, it makes a really nimble quad, super nimble. Also, I've got 5000 miles on my '07 450 and its still rock solid. Lets see a Po-Po go that distance without some major work, lol.

You already have heard others explanation of the differences and you can do a side by side comparison on Yamaha's website. It really is all a matter of personal preferences and budget. If you haven't test driven them both, you really should. It will help a lot in your decision.

I have had a 450 and now the 550. They are both excellent machines.
For me it came down to the most options for the money. I thought I was going to buy a 2010 450 non-eps a dealer closest to me had for 5900.00 (which was a very good price by the way) then another dealer offered me a 2010 550 with eps for 6600.00 both camo. The 550 was just to hard to pass up with the options for the price. I am glad to have the efi and power steering without breaking the bank to get them.

Best of luck in your search for the ultimate machine. You will be happy either way.

Thanks for all the info, I had no idea they were not the same size. The majority of where I ride is tight trails with a lot of rocks, trees and tight turns, sounds like the 450 would be a better fit, I am at sea level as well not much elevation. I will try and test drive them both with and without EPS.
Thanks again for the info.

Which way are you leaning right now, 450 with power steering might actually come in handy from the type of terrain you ride on.

550! Both my DW and I have 4000 miles on our '09 550s in less than a year with NO problems! Would not ride without EPS and EFI! The DW rode a 450 and thought the 550 would be too big, but now is glad she went with the 550. We have rode from sea level(Florida) to over 13,000' in Colorado and many difficult trails throughout the West-Moab, Silverton, Dubois, Taylor Park, etc. The extra 1" of clearance has come in handy and the extra 10 hp comes in handy quite often.

I would go with the 550 no matter what. That extra power sure will come in hand and unless your literally squeezing your way between trees all day long you'll be glad you got it.
