Tossed the stock rims and knobbies for a set of 17" wheels--Talon hubs, Morad rims and Sportec M-1 rubber were a great improvement for road handling. The stock 2 pot caliper with 220mm rotor was fine for dirt, but for street riding I needed more. I went with the MotoMaster racing kit, it came with a 4 pot caliper and a 320mm floating rotor. Just for good measure, I added SS lines.
