The design of the Pro-Race silencer was inspired by the first prototypes produced for Moto GP.
Pro-Race silencers are constructed by assembling a tapered section (the main body of the silencer) with a Ć98mm cylindrical end section, in Nichrom (a stainless steel alloy). The mufflers are attached to the motorcycle by means of brackets welded to the main body; their cone-shaped design allows a reduction in size and weight, but as this also reduces the overall volume of the exhaust, thus limiting noise damping, some motorcycles cannot be fitted for development and noise reasons.
Compatible only with model fitted with two lambda probes
The heat shield is optional (reference: 11004MI)
