Arrow GP2 comes from experience and style that characterize discharges of the new class rainbow "MOTO2" to meet the needs of those bikers who want to equip their sports maxi, Japanese and not with something less "normal". Discharges GP2 are only available in version slip-on (+ silencer link Pipe), characterized by a silencer extremely light, entirely made of titanium, of cylindrical shape, with very small and short gas outlet straight cut a slice of salami. The increases in power, although it is only slip-on, are very respectable and "sound" is really "bad". Where provided, also the holding clamp is made of titanium, in style "Racing". Another peculiarity is given by the exclusive Arrow logo, designed specifically for this line. Available only in racing, discharges are still prepared to house the dbkiller that was developed for the GP2, purchase separately.
