The video you've all been waiting for.
I think youre right actually.... hmmmmmI think we probably should use the uncorrected horsepower numbers. The SAE correction for temperature, atmospheric pressure, and humidity should not apply to electric. The 79 HP number looks a lot better.

As the battery warms up a bit its internal resistance goes down a bit so more power can be delivered.
The vector control software has not been fully tuned yet. The commutation angle and flux weakening is not yet optimum through the RPM range. Therefore the funky shape of some power curves toward the higher RPM range.
I think this has to do with the different dyno rear wheel that is installed. I wonder if the wheel size can be changed in the app (for supermoto for example.).I thought it was interesting that the dyno top speed showed about 10mph higher than the app top speed. Which one was correct? I am assuming one has a different tire size or final drive ratio in the calculation.
The yz will be putting down more power if it's ridden "on the pipe" than a standard 60 hp SV at motocross speeds?
The YZ can produce full horsepower in 1st gear at 10 mph, but it cannot put it down. Neither can the Stark Varg.Stark trace is set in stone (except for mapping) but yz trace can be shifted quite a bit to the left depending on gear selection.
I was thinking the yz trace was done in top gear. Theoretically the yz should be able to make 50 hp in any gear and therefore make more power than a SV at speeds falling within whatever window is encompassed by a yz in first gear. ie 30 mph: Stark is limited to about 35 hp no matter what? yz could be making max hp (50+) in first gear at 30 mph

Oh wow! Even if geared for top speed, it will still beat the KTM 450 easily.Based on Bryan's screenshot of the dyno HP vs speed chart, I've estimated RW torque and compared it to a KTM. The KTM is a 2017 450SX modified to 60 RWHP. The SV torque figures are approximate, based on the dyno chart and my estimates of primary gear ratio, sprockets and max rpm. It looks like the characteristics of the SV electric motor with probable low rpm current limit, then constant power limit then other reductions match the torque of an ICE with gears.
The top speed of the KTM in Supermoto setup is about 160 kph. No idea if there are any speed limits imposed on the SV by its controllers. If not, it could be a fast and capable Supermoto bike, but I'd like to hear from anyone that's tried it.
(usual warning... random posts on the web might contain BS... but the SV data below seems to match other quoted info at least approximately. The speeds are only dyno speeds, not actual.)

My experience is kind of the opposite.Oh wow! Even if geared for top speed, it will still beat the KTM 450 easily.
