The mototech ones are �116 from germany free delivery on ebay, but the yamaha one is about the same price from a yam dealer, �120 or less i,ve seen them from a yam dealer .i,ve had the yam one on a previous bike i had and gave it a few bashes and was it was ok, pretty sturdy.
Quality wise they both look the same, id be more inclined to order one from a yam dealer.
