I recently bought a Procircuit Shorty for my RM250.... I have the Pro Platinum pipe and standard PC silencer but alot of the tracks have converted to the more twisty power out and into corners type of track of yesteryear that favored the 2Ts.... Anyway I had to go out and buy new grommets because PC doesnt supply the black rubber mounting grommets..... They were only $4 but I feel that PC should have provided them....or atleast said no grommets provided.... Not a big deal other than having to order an extra $96 worth of stuff from Motosport to get free shipping and then wait another week
