Is it a ticking noise?
Does it sound like a spray paint can when you shake it?
If it's a ticking noise, my '08 R3T did it. It was nothing wrong with the bike; nothing that would harm the bike. Triumph referred to it as bucket stacking. It was going to be corrected at the 10K service, but I ended up selling the bike. Again, it wasn't something that was going to harm the bike at all.
If your bike is making the dreaded paint can noise, then you have a problem with the cam chain tensioners (I think that's it). Anyway, Triumph is aware of it and there is an "upgrade" kit that they will put in free of charge. I'd be surprised if you have that issue, however, as I thought the bikes newer than 06 were corrected at the factory.
