I have had my Wolverine 450 for a short while now and I can honestly say it is absolutely the best trail based ATV I have ever ridden. The power is perfect (I don't get why anyone says different), and my last ATVs were a Prairie 700 and LTZ 400.
The thing about the Wolverine is that it can power slide and handle like a sport quad, but then can also overcome just about any obstacle you can find while in 4x4 mode. The lack of overall mass is great, too; no more worrying about squeezing between trees and you can pick up the front or back end with no problem if you get caught up. This is the ATV you want for everyday trail riding!
The suspension is very compliant, and the midrange power is fantastic. I am also very impressed with the smooth transmission. I have a good feeling this thing will be bulletproof.
Overall, I am very happy with this purchase!
