Hey everyone,
I wasn't able to find a fitting, existing thread so I hope it's ok, that I opened one.
I recently bought a MY21 SR/S Premium with the 12kW charger. It was a demo bike with 2300km on it.
It has been fairly cold since I got it (0-10°C) but the last couple of days it has really warmed up.

My issue: the bike seems really quite slow, mostly concerning off the line acceleration. I've seen multiple videos on Youtube where people do 0-100km/h on SR/Fs well below 3.5s (mostly 3.3s) and they all were in Sport mode. The fastest I could manage yesterday was 4.3s.

Here are some details about the ride:
I did several test runs just now (dry, smooth, grippy road, charged battery to 95%, battery temp in the white center, 16°C outside) in sport and custom (everything up to max, top speed always reverts back to 108mph) mode and wasn't able to get the 0-100km/h below 4,27s. I've seen SR/Fs in video reviews doing it in 3,3s. The ride capture only registers a maximum torque of 176Nm and a maximum power output of 59kW at +120km/h. I had the bike at my local dealer two weeks ago to update everything. Traction control was set to sport (had turned it off another day, didn't feel a difference, didn't measure it either though). I weigh 65kg plus gear (helmet, etc.).

My question: I would love to hear from other SR/S or F owners if they managed to get decent 0-100 times. I also recorded the ride and the max power output only reached 59kW, I accelerated all the way to 130km/h, where max power output should be available (dyno charts).
Thanks in advance.

Also, how do I implement an image? I hope the attachment works.

Why is maximum power showing as 59kWh?  Surely it should be 59kW (as you correctly stated).    Is that a Tesla app?

[ZeroJan]

I don't know why they show the power output incorrectly as kWh instead of kW. Should be at 80-82kW though, since I used full throttle in a straight line above 115km/h. It's within the Zero app. I also have the Tesla app on my phone, which is why it's showing up in the status bar.
The SR/F and SR/S should be the same in terms of power and acceleration, right?

I don't have my SR/S yet ('won't until next week), but I've been playing around with the iPhone App in preparation.  When I look at the default "Sport" ride-mode in the app, it seems to imply that it'll only use 80% of the power, and that you'd need to create a "Custom" ride mode to use all 100%.  Could that be the case here?

[SandyGnomes]

Just checked my app for my 2021 sr/s and "Sport" mode is 75% power.  The kWh thing annoyed me too.

[ZeroJan]

Almost all test ride videos show the sub 3.5s runs in the regular sport mode. I was in custom mode with everything up to 100% (except for speed at 108mph, due to an app error) when capturing the ride in the app.
No SR/S riders with timed runs here?

What are you using to time your run and does it include a 1ft roll out? I only managed to find one review who presumably used some kind of timing equipment (they also have a 1/4 mile time) instead of filming the dash or just repeating the 3.6 second number that gets thrown about with no source and they got 3.7 seconds. No mention of if that includes roll out but assuming it does that would be a real time of more like 4 seconds and a 4.27 0-100km/h doesn't seem unusual.

Could Zero's acceleration numbers be the result of their testing on their factory dyno?    That would be the easy way to get a good result, rather than hitting the street and using a stopwatch.

Zero doesn't give acceleration times (anymore, apparently they did in the past) but even if they did they wouldn't do it that way. No other manufacturer does, there'd probably be some sort of false advertising lawsuit, and if there was no chance of that they'd just use the 1.6 second time that other people have got on a dyno.

[ZeroJan]

I had a GoPro on my helmet filming the dash.
All the videos I watched timed it that way and got 3.3s in multiple videos. It doesn't matter to me, if it's the perfect timing method. But it is very comparable to the other videos which clearly show a much quicker bike.
Anything above 3.5s isn't acceptable to me, considering the stated performance and price tag. Many others have proven the bike to be more capable than mine.

Best thing to do is get it on a dyno and see what's happening.

Filming the dash isn't a very good method at all. It doesn't update anywhere near quick enough to get an accurate time, the speed displayed isn't accurate, and it doesn't even show every number (one review I was reading that timed the bike this way didn't get a single recording that ended at 100km/h, it was always a few km over). All speedos by law have to read a little high which can give a quicker acceleration time.

Using the GPS on your phone and an app would give you a more accurate number, better still get an external GPS device like a Vbox or Dragy.

[ZeroJan]

This is totally not helping my issue though.
Other people get low 3 second runs filming the dash. My bike is a full second slower, using the same method. I don't want crazy accurate 0-100km/h times, I want my bike to be a second faster than it is, because other peoples bikes are. The timing method is totally irrelevant.
Helpful input from other SR/S and SR/F owners would be:
-0-120km/h runs with full throttle in sport or max mode + ride capture (what is the max torque and power output?)
-0-100km/h times, rider weight, outside temp

Again, this is not a problem of measuring the runs. I would like to have comparable data from other owners. If everyone achieves 3.7s and lower, then I can be pretty sure that there is an actual fault with my bike.

But not only is it inaccurate it has the potential to be inconsistent. Other riders bikes might update their dash at a faster rate and read a different speed (varying tyre diameter), their camera they're using to record might be off a little, their method of measuring the time might be off, etc.

I seem to remember there was a "beast" mode that would open up the full power.
I don't remember how they unlocked it.
