HP is also dictated by what the motor delivers. And by the gearing. HP is independent from the gearing of the motor.

Yes and no. The total amount of it is dictated by the motor. At what speed it happens is dictated by gearing.

For example an ICE with 6 gears and meets peak hp 6 times over the wheelspeed range. At say 15, 25, 45, 60, 80 and 90 km/h depending on the gear ratios per gear.
Same applies to different gearings (wich are actually just gears that you can't shift but have to swap sprockets for) on an E. The lower the gear the higher the horsepower at lower wheel speeds and the other way around.

And an Stark does not have any gearing. But delivers over the whole rpm band. With nearly konstant HP over the whole upper band. No need for switching gear and looking for the right rpm band. So no need to change gearing. As long as most riders dont even use the full 80HP, but chose to drive with 50HP-

The speedo uses gps, there's no pickup for a traditional gauge and I'm not sure why anyone would want one. I commute on the bike during the week and mostly run the BRP on the weekends.

I could run a smaller sprocket on the back and maybe pick up a few miles if I ran interstate at sustained speeds but that's not how I use the bike. I'm in and out of the throttle on tight backroads for the vast majority of my daily commute.

I did a 200 mile day on my 2t motard a few months back and by the end of the day I was wishing I had taken the truck.

IIRC the Stark uses a countershaft sensor for mpg? I really don't know for sure, but yeah GPS is best. You don't seem to have a range issue, but the rideability is enhanced with taller gearing anyway IMO. It's not just for Supermoto and freeways.

On this past Sunday I got 15 miles of slow mostly single track with some Enduro gnarly hills used about 35% battery. So I could comfortably get the same as @Johnny Depp in the slow gnarl.

I am mostly stock with my newer Varg. Some Acerbis parts and an AXP skid plate still running the Pirellies (with IRC heavy duty tubes) till they are worn out, they don't like the 8 psi...

Hopefully more people will report back as you did, we need to standardize the math so that we can say I got X mpbattery % today so that we can learn from the comparisons.

Just read the last post again

The HP per wheelspeed. That's what the car industry has been doing for over a century and it's actually what gearing does.

The horsepower curve is also not flat. It is an actual curve. Just look up that dyno i posted not that long ago.

Edit: Here it is:

The top ond is the 80hp, wich you can see collide with the 60 and 70hp near the end.

I'd love to see something more current, there have been several mapping changes and IIRC Bryan had problems with wheelspin and the 80hp setting not being unlocked?

The intent on this thead was to demonstrate range increases (or not) with super tall gearing and zero Regen. It also increases rideability, less abrupt response, less wheelspin and wheelies.
