Just Do-it, you wont be sorry. Dollar for dollar though when you do decide to mod your new shee, a two stroke will have more power than a 4 poke and it will cost you less to get that power. Two strokes react very well to mods, but to increase a banshee say 20 hp will cost less than to get the same 20 out of a 4 poke. As far as ridability goes Banshees, as their namesake scream, and they like to go fast.
By no means think that you are invincible on one though, because there will always be someone faster than you that has more money to burn. Like they say you can only go as fast as your wallet will allow, but man there is nothin' like it.
You need to try out a friends shee or find out if maybe a friend knows another friend that may have one. Or find one for sale and take it for a wide open pinned test ride and you'll be hooked. If you are interested and have never been on one you're already hooked, now just follow that feeling..............
