My family has a stock 2013 900 xp4 we recently purchased with 30 hours on it.

With 4 passengers it will run 70mph at 9250 (according to the gauges) and with 2 riders it will run approx 75mph at close to the same rpm (honestly I didn’t look that close and could have been slightly above 75). This is on hard packed fairly flat sand.

This Is My first rzr, just wondering if this is the correct stock performance, and if I would benifit at all from a clutch kit?
