I know there's a noticable difference between the Grizzly 350 & 450 when it comes to power, but what about the difference in power between the 400 & 450.
Wanting a 2008 or 2009 Grizzly 450, but have a chance on a deal on a 2008 Grizzly 400.

 

I think the 400 is a 401cc and the 450 is a 421cc. The 450 has a few goodies I don't think the 400 has. A Park gear (which is nice), low gear, (good for pulling and plowing), and maybe (not sure) a diff lock for 4WD which is great for deep mud and snow. As far as power, I've owned both and I feel the power and speed was very close.
Hope this helps
(BTW just picked up a new leftover Grizz 450 for the girlfriend today)

The 450 is a better all around machine than the 400 and with enough engine to do about anything you want and need. If you go for the 400 you will always wanting and be needing more. The 450 IMO is one of most underrated quads made!

 

Thanks!
In between the time I posted this question, and seen your reply, I did also find out that the 400 does not have the diff lock feature....that puts it out of the question.
No parking gear is no big deal, but I do like the low gear option, so it looks like I'll still be in the hunt for a 450!
Thanks again,

I had a 450 before I got the Thundercat
I put 5,000km on it and never replaced a thing
Tops out around 90km/hr and lots of low end torque
