2004 Rocket and ULEZ.

Amazingly, my bike just got the thumbs up from the despots at TFL and is no longer applicable for a ULEZ charge. ULEZ limit is 0.15, my bike makes 0.11 according to the logbook. It's a pretty easy process to apply and obviously worth doing if you go to London.

Even though it wasn't needed in the end, Triumph sent me a certificate of conformity for free, that's good service seeing as some other manufacturers will charge anything up to £170.
