I bought my 2005 Rhino in late 2004. The Rhino's had problem but they were easy to fix. I'm way too old to wait and have enjoyed 52,000 miles in side by sides. The Pioneer 700 is my 9th side by side and I still have my 2011 RZR 900. I don’t use it much except on the fast paced rides with friends and I always take a tow strap, it has over 9,600 miles. It has too many problems and repairs to mention but I keep it in tip top shape.
I bought the 2 seat model for the 140 pound lighter weight and geared it up so I could cruise at 45 mph without being above the power peak. On the fast sections I cruise between 40 to 45 and stay under 6,000 rpm. This Pioneer will get me by until I can buy a reliable sport model from Honda, Kawasaki, or Yamaha.
I’m running 30 inch GBC Mongrels on 14 inch bead lock wheels with a top speed of 51 on the flats. It holds the hills good at 4,500 to 6,000 rpm in the peak power range. Red line is 6,800. The 30’s don’t clear at full lock and when the suspension is compressed so I don’t recommend them but I really like the ground clearance for rock crawling.
The 2015 Pioneer may have the twin spark plug cylinder head and an oxygen sensor for better emissions and gas mileage but it will have the same HP at about 36.5.
Honda and Yamaha will have Sport Models with good build quality and I expect Honda will announce sport models this year.
