Since Euro-5 Regs, yes as far as I am aware. That's why so many bikes were retired from sale a few years ago as they were running carbs which don't like cats particularly. There's a chance that if the M3W is not on the Testers list of vehicles (as indeed my 1999 grey Jap import Subaru wasn't), they just have to do a BET (Basic Emissions Test) which has limits waay higher than for vehicles that are on his list.
I'd keep it on the garage shelf ready for action if I were you!
