Just purchased a 1999 atk 490 it has 17" excel wheels laced to the stock talon hubs. I love the bike so far, but I would like more performance from the front brake.. The bike still has the stock front brembo caliper and stock front rotor, I would like to replace the stock rotor with a galfer wave type rotor in a 320mm diameter, and along with that this mod. would require a caliper relocation bracket, however I am having a very difficult time accumulating any information on such a modification (part numbers, sources etc). Does anyone know what I need to look for, or where I need to look to to find this information??
