Sparks Racing
has been building big horsepower engines for
several decades now with former Pro racer,
Curtis Sparks, running the show. Sparks has
a long history in ATV engines, but in recent
years, Sparks has expanded into SxS Racing,
and in 2013 both Beau Baron and David Haagsma
won WORCS SxS Championship with Sparks Racing
engines.
Recently, we had
a chance to test drive Sparks Racing's Polaris
RZR XP 900, which was specially built for
the sand dunes. This RZR XP 900 was far from
stock with a big bore engine that could eat
up a stock Polaris RZR XP 1000
