The Imperial Sand Dunes Recreational Area in southern California is a great place to test the true grit of Yamaha's big bore Raptor Sport ATV. Sand dunes are a completely different terrain than riding on a track or in the trails and conditions can vary greatly from day to day, requiring versatility and dependability.
The South Dunes of the ISDRA provided ideal conditions for what is one of the best sport class quads we’ve tested to date, as the Yamaha Raptor played king of the hill at Gordon Wells' Test Hill. It went almost entirely unchallenged when it competed against other stock quads of all sizes. It also made quick work of just about every other ATV it ran against at the sand drags above Dune Buggy Flats. The biggest challenges seemed to come from some slightly modified 450cc race based quads.
