Off-Road Vehicle

An off-road vehicle with front and rear seating has right and left connector assembles connecting a front top bar, a B-pillar, a rear top bar, and a middle cross beam of a Roll-Over Protection System (“ROPS”). The connector assembly includes a front top bar connector weld to the front top bar, a B-pillar connector welded to the B-pillar, a rear top bar connector welded to the rear top bar, and a cross beam connector welded to the middle cross beam, which are bolted together using only four bolts. Various inventive aspects strengthen the frame. For instance, the frame includes a rear sloping beam, sloping rearwardly and upwardly, positioned adjacent the rear seating. A rear door is positioned above the rear sloping beam, with its pivot axis toward a rearward end of the rear door, but spaced well in front of a rear post.
