I'll tell you guys one more time... the torque characteristics of an engine are determined by it's cams and how they're installed (lobe separation angle). Exhaust and intake tracts should be matched to cams.
My mistake I never saw the 0-60 in 2.5sec on the first post I think quite a few of us like going over 60mph as do most bikes on the road, in the cruiser class we are in the top 5% but a lot of owners think we can blow off most sport bikes and this is not the case.
Spend the money on what ever you like my point is. If you are not planning on racing for money or slips why bother the bike has more on tap than you will ever use. When was the last time you ran the throttle wide open for more that a mile.
The answer to your question is only a couple times a week, do I hold the throttle open for several miles. It gets to speed much quicker and smoother. It was very hurtful having small displacement, slightly modified, air cooled motors out accelerating me.
I've gone from being disappointed with the performance, to being very happy, but
there are still some simple, inexpensive power to be had. Still talking 87 octane, with a very smooth power delivery. Simply unchoking the terrible thing Triumph did to the Touring.
