I don't know what those U shaped things are but someone will chrome them straightaway. Sad to see the robot welded tube frame similar to some of the KTMs. I'm sure it's strong and all but I'll take an alloy frame with rows of coins welds over that anyday!

Not me.  I'm having fun balancing my wildest fantasies against economic and technological realties.

There is a reason that KTM and Ducati use trellis frames....  They are extremely strong, light and relatively economical....  Each their own....  BUT,  I  think that Zero might actually be on the right path to pull dollars from my hand !!!!  I really like what I see so far....  Hopeful....

With what seems to be the same battery I'd say same voltage so likely no DC fast charging.
With the larger motor and maybe the lure of increased efficiency, doubling the voltage by stacking the batteries might be part of the design.

I'd be surprised. The way they've talked about the superior safety of the lower-voltage systems in the past, it would be quite a turnabout for a significant boost to the voltage.

One of my Physics professors back in college told me the reason the US uses 110VAC for domestic power is that it's "usually not quite lethal". I guess that is better than "usually quite lethal".

So I know we are all trying to figure out the 75-10 motor.  I know Zeros currently use 75-7.  I offer this explanation form RideApart:
"The 7 stands for the size of the motor's rotor (7 cm = 2.76 inches); it is the biggest unit Zero currently offers. Logically, the 10 suggests the new motor is getting a bigger rotor—close to 50-percent bigger—which in turn means the output numbers will get a significant boost."

I don't know what you guys expected, this teaser gave us more information than either of the previous 2 teaser images, we already know we'll get all the real details on the 25th. Even so, we got a lot of information from one little image and video than previous teases. Trellis frame, dual from disks, new motor, better cooling, same KWH. That's a lot more meaningful info than "LED Headlight"

I still think you guys are overlooking the trellis frame. That's going to add huge weight savings. There's a reason why every motogp bike has a trellis frame. They're extremely strong and light. Compared to the solid steel frame on the regular SR models, it's going to be a big difference. What will be interesting is if the frame is aluminum or steel.

14.4kwh doesn't mean it's the same battery, it means its the same capacity. The outside shape still tell us it's a different design. Likely a higher voltage to support fast charging. Also likely that it has much better cooling. The fact that they've talked about lower voltage being safer in the past doesn't mean they won't go high voltage now. The market wants DC charging, and this is how you do it. They've also had a decade to think about possible safety solutions for a higher voltage system.

It's likely that the same capacity battery with a lighter frame and other improvements will get significantly better range than the current SR model.

U shapes are bolting points for what looks like a new 2 part long brick battery with what looks like a chiller plate/ frame mounting point in between them.  Very nice!
Same voltage or higher isn't known but "seems" unlikely to be different being the exact same capacity IMO.
We'll see.
But sorry Caza the frame has always been aluminum not steel and not very heavy but trellis will give them more flexibility for sizes of batteries and other components in the future so that's cool too.

Seems like my predictions are right  8)
Zero doesn't come with a 20kWh battery but with a horizontal ventilation duct.

Since every other new ebike has fast charging it would be stoopid for Zero not to - so that should be a given. The 75-10 motor would probably indicate roughly a 100hp motor. My energica has 109hp 133lb ft so I would guess it would be very similar here. With the Lightning Strike coming out now as well with 150mph, 150 miles and CCS I would imagine this will be close to that. I predict 150 mile range and CCS for this. Dont expect the trellis to make it "lighter" - the main weight issue is the battery so 475lbs or 510lbs doesn't really mean much.

Someone 'shopped this image together in the FB group. Thought I'd share here!

Just because it has a 14.4 battery, does not mean it can’t have a 7.2 or  another 14.4 also.

All I’m saying is trellis frame and cooling fins. DOPE!

The trellis frame illustrated is in all probability chrome-molly....  The welds definitely say steel....  An Aluminum frame in the diameter tubing shown would be an absolute noodle....

No Caza was saying the current SR frame was solid steel.  It's not.
I can't say if the tube frame is alloy or pure steel.  I like it though.
