have many people delt with them in alberta at dons speed parts??? i found them a rip off. they sent me some 75g weights i asked them for non set screw for my 03 zr 900. they were listed at $85usd on the internet site. they send me set screw ones with no bushings. and they worked out to be 130 canadian! there answer was. well go to youre nearest cat dealer and spend 10 bucks a bushing. so im into these weights for 160 and some now. i said howd 85 USD turn into 130 canadian???????? with an exchange rate of 1.20 on the high days. his excuse "thats how it is". i dont know but in my mind RIP OFF ARTISTS. ive ordered many things from usa and never got an exchange right like Dons Speed parts uses. let alone have to run around and get bushings for a new set of weights that shoulda had them. hope others have had better luck than me!
