The growing popularity of Youth model ATVs has led to some exciting advancements in what is available for the next generation of off-road enthusiasts. Polaris leads the industry with more models than any other major manufacturer and is the only one with a Youth-sized Side-by-Side in the extremely popular RZR 170. Polaris also sized down the popular ACE model with the introduction of the ACE 150 EFI. These machines are for drivers 10-years of age and older, and are similar to the vehicles the adults enjoy.

Both machines have some similarities, being off-road Youth machines with full-enclosed ROPS systems, steering wheels and seatbelts. So it really comes down to what your youngest drivers want – seating for two, or for one.
