I'm presently riding a recon and need to upgrade to a faster,bigger machine . The quads that I am currently looking at are the 300ex and 400ex. My first concern is that 80% of my riding is on some sort of trail, the rest is blazing my own( not to rough ).I weigh 190lbs and I'm about 5'10". I like to go fast , but yet don't whant to have to go fast .I really worry about how fast is the low gear on the 300ex and is it the same on the 400ex. Also is a sport machine what I'm looking for or should I look into the new rancher sieries. Any advise is greatly appriciated thanks.
