capacity. Additionally, an updated Power Tank will be available later
this year to offer an additional 6kW of capacity, bringing the total to
12kW and allowing a 0-95 percent charge in just an hour, with a full
charge 30 minutes longer.
However, the charging station must be capable of providing that much
current, which many are not—yet. Unlike Harley, Zero doesn't yet include
Level 3 Fast Charging, because 90 percent of the charging stations in
the USA and most of Europe are as yet only Level 2. With a fully charged
battery, the SR/F's claimed range is 161 miles in city use (but adding a
Power Tank will increase this to over 200 miles), 82 miles in Highway
mode (at 70 mph speeds) and 109 miles in a Combined cycle. That's
actually about a 10 percent drop compared to the previous SR owing to
the higher weight, and those larger tires delivering extra drag.
MISSION
CONTROL
T
o interlock and control the ar-
ray of interrelated systems that
are contained in the SR/F, Zero's
engineers have now created the
Cypher III operating system to act
as the central hub, while delivering
four pre-programmed riding modes
(street, sport, eco, rain) and up to 10
programmable custom modes which
allow the rider to customize the bike's
performance via the no-cost Zero
app, and TFT dash interface. Cypher
III integrates the 12V system, 100V
main battery charging system, battery
monitoring system, controller, Bosch
MSC/Motorcycle Stability Control,
TFT dash, app Bluetooth connection,
and cellular connectivity module. The
SR/F is also the first electric motor-
cycle to utilize Bosch's MSC system,
a benchmark for dynamic accelera-
tion and improved stability regardless
of road surface or conditions. When
combined with Cypher lIl, the MSC
delivers straight-line ABS and corner-
ing brake control, traction control and
drag torque control. Everything is
seamlessly connected for easy and
intuitive control that's essentially ef-
fortless—as claimed!
seemed genuinely surprised I would
ask for this—have missed something
here that I hope they'll rectify in future
versions of the bike.
Okay, I can switch to street to
have less intrusive regen, but then I
sacrifice the more immediate hit of
maximum torque I want when I get on
the throttle again to drive out of the
turn, often uphill.
BORN WELL
But it's a mark of how successfully
Askenazi & Co. have re-invented
the street-legal E-bike that that's all
I found to complain about in my two
days aboard the SR/F. Besides the
truly mind-blowing acceleration, its
high-speed handling was deeply
impressive, too, tracking straight and
true on a short blast up to the 124
mph indicated top speed, and deliv-
ering a confidence-inspiring sense of
being truly planted as I flicked it from
Zero's worked
tremendously hard
to make a motorcycle
that corners like a
regular machine.
