Outward appearance might have you thinking that the RMX is simply an RM-Z dressed up with the usual enduro gear—lights, 18-inch rear wheel, digital enduro instrumentation, coolant recovery system, quick-access airbox and kickstand. While that is essentially true, there’s more to this bike than that, even if the X does retain much of the Z’s demeanor. The ergonomics match those of the motocrosser, and except for a slight change in the lower cradle, the aluminum twin-spar frame is identical to that of the 2009 Z. The engine is wider only because of the larger cover needed to accommodate the electric start components; any width differences between the rider’s legs are imperceptible. The X even uses the same fuel tank as the Z, even though its 1.6-gallon capacity is absurdly small, especially for serious trail riders. On average, after only 30 miles of riding, the low-fuel light on the dash beams, signaling about a quarter-tank of remaining go-juice.
