I just watched this short video explaining the Triumph 900 "T-Plane" 3-cylinder engine. Near the end of the video there's an on-board-camera clip that gives you a good opportunity to hear the engine rev under hard acceleration. You're not going to believe how much this engine sounds like a VFR800 engine.
If you don't want to watch the whole video just skip to 3:10 and listen to how Triumph stole the sound of our VFR800s.

The cylinder firing order of the "T-Plane" engine is almost exactly the same as our VFR800, just without cylinder #4
VFR800 = 1-0-1-0-0-1-0-1-
Triumph = 1-0-1-0-0-1-0-0-
