No, not factory. When I met my wife I had a TT600 which did come in that colour from the factory, the same as the Daytonas. (Triumph Racing Yellow) She noticed that the bike stood out a mile, and if we happened to be on the way home from work at the same time she'd see the bike a mile off, and was convinced that having a bright yellow bike was safer as it made me more likely to be seen. A (good) few years later and the TT is getting on a bit, so I'm talking about getting a new bike, to my surprise she said "Yes, you can have any bike that you like, as long as it's yellow." So I did a deal with the dealer and got the Sprint sprayed in Racing Yellow as part of the deal. I also got to keep the TT as the trade in wasn't worth much.
