Stalling a manual clutched machine is generally due to rider error. However, it the quad is geared high, like the TRX700xx, it IS easy to stall. Gearing it lower fixes this issue. Never had problem with stalling on any other quad. While the 400cc quads from Honda, Suzuki, and Kawasaki are all great quads, 6' 3" is pretty tall for a 400cc quad so you might feel a bit cramped. As you already know, the 450cc machines are better suited to the track and are a little more challenging to adjust the valves on since they require shims. Take your time and TEST RIDE as many machines as you can, especially the quads you are interested in.

 

Pick up a lt250r or a quadzilla 500, the ltr250r can easily hit 70, and the quadzilla 100, or a banshee witch is inbetween them both but banshees are bulky as fk mainly just made for drag racing imo

 

Your azz will tell you which one fits. Most all quads today will hit 60 mph. Not all will be comfortable for a 100 mile trail ride, many won't be great in deep mud, plowing snow, etc. I tend to think sports quad is the Miata , ATV is more of a work horse, and the UTV's are the Raptors.

 

I have to admit that going faster sounds like a lot of fun however those sudden stops when going fast can catch up to your body real quick. I don't like the idea of getting hurt and not being able to get out and do things. A few years back a friend was out cruising on his sport bike at around 60 mph and had a tire blow out, ended up with quad out of control and flipped, broke his back. Went two years before he could ride again, and as he states....never going to go that fast on a quad again!! He now owns a utility quad and believes if he had one before his accident he never would have flipped it. Who knows.....I do know that I am not interested in going that fast...not a big fan of pain and expense!!

 

For me speed makes little difference for my purposes.
I bought mine for icefishing (too bad the ice did't agree much this year) and some trail riding.
For trail riding I'd rather take my time & enjoy the sights compared to being on the edge while driving and having to react quickly due to high speeds.

 

This is inaccurate information. No stock, factory quad will do much over 80 mph.

 

Ha ha of course not stock, but after looking into it since he isn't big on speed a ltz400 or a honda 400ex are both killer quads and you can easily pick up ethir or for 2000$, they both have alot of power and speed if you get bored going slow, witch believe me ya will,
And they'd fit your current needs.

 

TA999, have you had a look at a KFX 700, also known as a V-Force ( early ones ). These are rather large sport bikes made by Kawasaki. They weigh in at about 515 pounds dry ( a tad heavy ), completely automatic, belt/clutch drive. They are quick, fairly fast ( 70mph ), wide, and long. You might have a look at one of these.

They are considered a "sport" bike, and the final drive is shaft, but to some degree I think a bit of a mixture between sport and utility. Anyway, they fit tall guy's very well.
