Crankshaft Question
I think the real reason Triumph developed the T plane crank was because it starts with a T.
Now they have pioneered triples, their trademark engine config that also goes with the word Tri-oomph, and they have a distinctive new crank which is named with a T for Triumph.
 
So.... if I'm understanding all this stuff.... the "T" plane is only on the 2500cc engines, right? So the older ones are ??? I'm so confused

Nah both generation Rockets, the 2300cc IIIs and the 2500cc 3s, are both 'normal' 120° cranks.
Only a few newer Triumph models e.g. Tiger have used the T plane 90°/180° crank so far

I thought the 2500 was a 120 degree, there have been some claims on both sides. But unless I missed it no confirmation on either side.

Probably would have been newsworthy on top of the displacement increase.
