I know i'm a bit slow but can anyone explain this , in the official Triumph Motorcycles Brochure the Firing Interval for the America/Speedmaster is 270 Degrees reading further on the firing interval for the Bonneville/ T100 & Thruxton is 360 degrees and the Scrambler is 270 Degrees - they all have the same capacity, bore & stroke & compression ratio. I thought the were all exactly the same motor. It seems to me that Triumph has done this 270 degree firing interval to eliminate vibrations.
Whats your thoughts

I think it's more for the exhaust note. The lesser vibration was a side benefit.
