I just picked up a used grizzly yfm 450 last week to get around in our small block forest to help out with collecting firewood, i like it alot, it has sufficent power for what i need and fits on my ute perfectly.

Yes, very likely. Every other spec is the same on both the USA and EU sites. Another mistake is where the USA site gives the same weight for both the EPS and non EPS versions of the GRIZZLY 550 and 700. The weight they give is for the non-EPS version, while the EPS version is heavier.

How do the Kymco MXU 450i's compare to the Grizzly's? I was wondering, because I keep seeing people on the trails with these Kymcos, but there isn't much test/review/comparison info out there. I really like the Griz 450's, just wish they had fuel injection, too.

i have a grizzly 450 in costa rica way up in the deep jungle mountains seven miles up a hectic road from the ocean technically its "coastal jungle mountains" there's just nothing worse ...... the real actual jungle eats and devours and destroys EVERYTHING my grizzly is an animal!! I've locked the differential and ridden right through mud slides washed out bridges through rivers ......... i dont know about other quads but i know that i cant have any electronic bullshit in this environment ........ the grizzly is a beast

Why wider?I like being able to fit where the big quads can't?

thats a sweet quad. theres a few of em here where i ride, alot more ranchers. i looked at one until price, will stick with new rancher but this is a really nice machine.

@reaped999 No, it's not a 4 valve engine. Go read the specifications on the Yamaha ATV website. The engine hasn't changed. If it had a 4 valve head it would say, like it does for the 550 and 700. In fact, the video say's it's a 2 valve.

@reaped999 The global site does say 4 valves. The US site doesn't. I don't know what engine they use in the rest of the world, but in the US the 2011 Grizzly 450 has the exact same 2 valve engine as the 2010 Grizzly 450, which is the same as my '06 Wolverine 450.

This handy agile bike fits me exactly, is 4 inches narrower than 420 Honda meaning no problems getting through sheep or hunt gates on hill land, not to high for jumping of and on at farm work, very comfortable and goes any where it's asked. One fault, needs a lower reverse gear.

Dear Yamaha, Please do not listen to this guy. If I wanted a bigger, wider, more powerful atv I would buy one, and everyone else would do the same. The fact that it is mid-sized in both motor and frame is what is so appealing.

what is efi?

@reaped999 Looking at a USA Yamaha OEM parts website, it shows only 2 valves in the head for 2011. So what I did was contacted a dealer in the UK asking them to verify if the 2011 Grizzly 450 really does have a 4 valve head in the UK, since it was the website for the UK/EU that said it's 4 valve. Hopefully I'll get an email response soon. Since every other spec for the EU is the same as for the USA, I suspect the EU site is wrong. It does happen.

@PyroHeiko Thank you!

Do any atv manufacturers ever reveal horsepower ratings? What would be the horsepower of this atv?

I want one soooo bad... Guess im gonna have to go fishing again this summer.

which do you guys prefer? the polaris sportsman 400, or the 450 grizzly

Love this vid! Im getting one next week!

y love the grizzly 450 it was my thirst favorit atv

Grizzly. Quite a bit less weight. Less weight gives a performance advantage in almost every recreational situation. You get to decide when to put it in 4wd and lock the front differential. You can put it in 4wd and lock the differential BEFORE you lose traction, instead of having to lose traction before it goes into 4wd like Polaris. And you get to control the front/rear brakes seperately on the Grizzly. The Polaris probably rides better and has more power. That's the only advantages.

@PyroHeiko yeah i know what it means, but is this atv fuel injected?

Def would be nice to see EFI.

Hola diferencia entre un Grisly y un kodiak de 450cc. Gracias

What the paint on my front and back bars has never chipped off

Hey y'all need to do a test on Kawasaki brute force 700

Yea-maa-haw

Grizzly for sure!

when its a 400 - 500 its a Kodiak when its a 501-max its a grizzly i believe or its 600

EFI?

no, doesnt even squek actually, just gotta run premium flue and they will last forever

Dang dude, these guys get way to picky. I mean I like to know what I'm buying but it's a little extreme.

ok sure

well why dont XXL riders just buy a 550 or a 700?

@catdaddyex i have a kodiak also, and it is amzing

grizzly 450

@ghetemihai no it isn´t

dear santa

@ghetemihai electric fuel injection

Wow, Dirttraxtv actually said the "K" word................. Love your show fellas but you really need to seek help for your Kawasaki phobia! Swing a leg over one and let us hear about it for pete's sake!

sorry but i disagree, honda builds the most reliable atvs in the industry, we have 2 honda rincons with 23,000 km, and 26,000 km. and a honda foreman with 17,000 and a honda rancher with 13,000 km. nothing has gone wrong with them majorly. just breaks,bearings the usual.

grizzly

TRUST me Grizz 450 ive owned both

diffidently polaris

Funny how you say that while giving no facts to back it up. Yes, Hondas are known for reliability/durability. What about the rest of the story? Such as the Rancher having no front locking differential and no low range. And smaller 24" tires. And less ground clearance. The Grizzly 450 has a front locker, low range, a broader torque spread from it's CVT, bigger stock tires, and more ground clearance. And it's durability/reliability is close to Honda. You failed to tell the WHOLE story.

Arctic cat rules!

ok let's put it this way. a shit that breaks monthly or a beast that lasts a life?

Sportsman Ive driven both :)

@ttr125dkb grizz

I bet the foreman smokes....

eps = waste of money

Buy a used sportsman 500. They are great and priced cheap.

honda rancher all the way grizz sucssssssssssssssssss
