banshee is like the honda civic of quads (but the shee is actually fast), they don't cost a shit load to buy a used one, and you can customize it to how ever you like it. the zilla is rare and already fast.
with a 2-stroke you are not going to get the best of reliability. man things is how hard you ride your quad and if you do any preventive maintanice each time you ride. another thing is make sure your quad is built right and tuned right.
as far as trails, the zilla is a tank as already stated, the banshee is kinda long. if you know how to ride your quad and somewhat know the trails almost any quad can be ridden in the trail.
just be smart about which quad you buy. don't take someone else word on which quad is better. people are bias. research each quad then go test ride them. know about the quad before you buy it/ride it. buy the quad that best fits you.
either way, you will not be disappointed with the power and badassness of a zilla or shee |
