so, utilitys canbe fun, and most have 4x4. no one, no matter what should sit on the rack, 2 can sit on the seat though. but i will tell you sport quads have better acceleration, speed, most are clutches, which is fun, and are smaller, so you can fit in tighter spaces. if your into racing and not going throught tons of mud and enjoy to struggle and get out of mud just in 2x4, then go for the sports quad. i would buy a sports quad way before a utility quad
