Side by sides (or UTVs) are becoming increasingly popular in the adventuring crowd. With the agile capabilities of an ATV, but the ability to carry a passenger right next to you, they truly offer the best of both worlds.
According to Power Products Marketing, the market has grown each year by tens of thousands of units sold—the only exception being 2008–2009, when the recession caused a slight decline. In 2000, the UTV niche sold approximately 100,000 units across the board. Fifteen years later, that number quadrupled, with more growth anticipated in the future.
It is clear that the market is healthy and viable, especially in looking at class leaders such as the Polaris RZR, which tripled its sales between its first year on the market in 2007 and 2015. As enthusiasm for side-by-sides grew, so did interest in quality parts and accessories.source
