Motor torque is nearly worthless without discussing gearing. Wheel torque is what you care about.

Speaking of gearing, the Zero SR uses a 30 tooth sprocket stock, slightly reducing final drive gearing from 4.7 to 4.4. This probably accounts for the higher top speed as much as any motor changes; curious that the top speed improved little over 2013.

A 98 tooth rear / 25 tooth front sprocket combination would give a 3.9 gearing ratio, which should raise sustained top speed to around 95 mph, peak top speed to around 115 mph, and slightly worsen 0-60 time (for the ZF11.4) to 3.7s.

I've had my 13s since Feb... I never thought I would even consider buying the 14 when it came out... but 106 lbs of torque and a bigger battery...... Anyone want a 13s with 4k miles  ;D

Tempting, but I think my wife would kill me and use it to run over my corpse.  ;D
I only *just* got away with buying my 2012 ZF9S...  ;)

I could think of worse ways to go Justin!

I am certain the SR will do more to break Jersey than any million dollar advertising campaign.  We are a small island with a massive motorsport community.  I said from the very beginning that my friends won't be interested in my electric bike until I overtake them on it.  We did an exhibition run with the 2013 S at the last International Motoring Festival over here on a very small loop circuit and 3 people standing next to me in the crowd said 'ohh...its actually quite fast isnt it.'

I am surprised no one has mentioned that the 2014 SR also has new suspension, brakes, and gauge cluster as well. I will gladly trade my 2013 for a 2014 for those 3 things alone, the extra torque is just icing to me. ;D

That SR is a good bike for Jay Leno to put in his garage...

So what agreement did you come too?

My wife is reluctantly on board too.

Agreement?

It went more along the lines of

Me: I'm going to look at an electric motorbike
Wife: Ok.

*I return from the dealership later* *

Me: Great bike, I bought it.
Wife: ...

She did agree however that I can no longer complain about her shoe collection.


*While I was at the dealership she visited a biker friend, who warned her that "going to look at a bike" was normally biker code for "going to buy a bike"...

Ah, nice.

So, what's stopping you from getting the SR? :)

Just go have a look at it...

All the gaps are getting filled in from the lower cost FX all the way through a $35K Mission (assuming Mission builds the bike).  Very nice.  Ebikes are real.

I think I can get away with that sort of stunt about, say, once every couple of years... ;)
So I'm going to hang on for what 2015 brings us.  ;D
