Dual Mufflers

Narita's machine was equipped with a dual muffler system, which was made by the Mugen Power company. After debuting the patented design on the production CRF250Rs in 2006 as an innovation that offered better chassis balance and handling, it was dropped when the CRF250R got a revamp in 2010. We heard rumors about the twin pipes making a return on the '13 Honda several months ago, so we weren't too surprised when we saw them on the number-one machine. We were surprised, however, to see an aftermarket system on the Honda works bike, as the team usually builds its own systems. MFJ sound limits are the most strict in motocross, and machines go through the two-meter max test in tech inspection, and again after each moto. And yes, Narita's bike had a distinctly different sound than the rest: throaty and low, yet nice and quiet.
