It felt pretty close to the perceived power of other Yamaha's that have the 847cc I-3, in the low-end and midrange. It doesn't have as much power at higher RPM. Yamaha says it's tuned-for-torque, which usually means milder camshafts, and sometimes other measures to reduce peak power, and lower the RPM of the power curve.
I don't have a lot of seat time on the other Yamaha bikes that use the 847cc I-3. Maybe a couple hundred miles total. My perceptions and likes/dislikes may or may not align with those of anyone else.
I didn't ask, but I'd guess it's probably geared lower too, to help compensate for the added weight of the front end.
I found myself grounding the peg feelers pretty easily, which is an early warning, as the amount the bike can lean is limited by the front end. Which means if pushed further one tire will lift off the pavement, loading the one remaining tire on the ground suddenly, and possibly beyond it's traction limits. Tires can take quite a bit of load while leaned over on the edge of the tire, but that load needs to be applied and released smoothly. Sudden changes to the load on a tire by lifting one of the wheels on this bike, or abrupt brake or throttle inputs as often happen in a panic situation, can overload the available traction. Catching a tire that is now sliding, is going to depend heavily on how much experience a rider has at the traction limit.
But this bike isn't billed as a sportbike, which is still my preferred style of bike. This bike is billed as a sport-touring bike, and in most circumstances won't be ridden aggressively enough to realize it's lean-angle limitations.
Anyway, that's my opinion, which is admittedly heavily biased to sportbikes. There has to be some reviews from some of the long-time motorcycle industry scribes. They should have ridden most of the bikes produced, and can give a more balanced review.
