Well if you did find a Speedmaster lower leg for that other rotor and caliper, you could possibly go with Brent's EBC floating rotors. Probably cheaper than Triumph's OEM stuff. The Master cyclinder is the same size, otherwise Brent would have to sell 2 different versions for the covers he sells. And in case you didn't know, the brake line for the right side of the Speedmaster's front brakes is merely piggbacked onto the banjo bolt fitting.
