I agree, they're not selling it based on power, and certainly not hiding it, it's on the landing page at the Triumph site.
Yes.
Part of upcoming EURO standards, I can't remember if it's only a proposal or already in effect, is that the ECUs are locked.
Other recent Triumphs still don't have ECU access, 3+ years on.
Dynojet is getting on CARBs bad side too, all their new/upcoming devices have hard limitations programmed into them, I'm told by a local tuner.
It's going to need a standalone to control fuel and spark, in concert with the stock ECU to run all the electronics and safety things.
Not an easy proposition.
I bet the power difference between the TFC and the R/GT is literally only how far the throttle blades open when at full throttle on the grip.
It's a nice, pretty, defanged rocket that's more approachable and safer. It will appeal to a different crowd of riders.
