Yes, there's a note on the Bike Bandit site, "Warning, deliveries for OEM Triumph parts will take longer than Bike Bandit standard ten day transit because of delays from the manufacturer."
http://www.worldoftriumph.com also has full parts listings and a webshop one can just click to order from. I've had good luck twice ordering stuff from there, but none of it was very esoteric (stuff like grommets for the side panels on mine, that so easily come off; I siliconed mine into place this time and so far so good.)
