Stinky, I got the trx420fm. all I can say is
WOW. Lots of Jam all through the gears. Pretty dang fast for utility quad, I 've had it up to 70 kmh with some throttle left. Thing I really like is 2/4 wheel shift select. Beats the hell out of my 200e trike.
I've got about 12 hrs on it and have only gotten it stuck once so far. My fault as I wasn't watching and sunk one side into a hole. Left the right side up in the air. lol Power wise its got the 400 foreman (2000) beat hands down. One thing I don't like is the smallish racks on it. But I can live with that.
Sorry Tbark, didn't mean to take over your thread. Just thought I would tell stinky he made a great choice if he gets it.
As for the one your looking for I don't like polaris. I borrowed one (different model) a few years ago for a weekend stint to try it out. You could smell it 1/2 hr after going down one line and returning. lol 2 cycle engines
