X2...I got a stick in between one of mine rears a while back a junked the oe boot. Put one of the "universal" ones on because local dealer gave me a STUPID price for the oe replacement !!! The universal is made out of a softer rubber...got maybe 6 months out of it before a couple of pin holes came in it. James ordered me the oe replacement (at a KILLER price!!), it comes in a "kit" with 2 bottles of grease, new clips, new bands, everything you need. The bands may be a little tricky w/out the tool yamaha uses, not sure...I picked up a band tool from Napa for like 30 bucks, and use the bands they sell (they're a couple bucks a piece)...they work VERY well, and you don't need three hands to put them on...real tight and don't slip !!Call Hot Rod! only takes two days to get to your door and great prices!
