well around a racetrack to begin
with," Wismann said. "Instead of
a 600-pound, 300-horsepower
monster, what we wanted to de-
velop was something closer to a
supersport bike that had a reason-
able amount of power but weighed
closer to 400 pounds or less. That
was another big focus, and that's
one of the reasons we call it the
Lightfighter."
Wrapped in that tubular steel
chassis sits a custom-built,
liquid-cooled Parker-Hannifin
GVM 210-100, constructed in
the company's New Ulm, Minne-
sota, factory.
"They designed it as a kit mo-
tor, so you can custom configure
it for a bunch of different appli-
cations," Wismann said. "So, in
this case, it's custom wound just
for this bike. Then we take the core of the power
and basically build the gearbox elements around it.
"This bike has about a 2:1 gear reduction built
into it. So, it's 162 Nm (119 lb-ft) motor but you
double that through the gear reduction out to the

rear wheel. Then that jack shaft
and that gear reduction element
allow us to put the countershaft
where we want for the chain line
forces on the swingarm, which is
similar to what you would do on a
gas bike."
Powering the motor is an actively
cooled, 410Vdc, lithium-ion NMC
battery custom-made by Ely Sch-
less using battery cells from Farasis
Energy constructed in China. If
you're in the electric vehicle space
you may know Farasis recently
became one of the largest tier 1
suppliers for Daimler and so will be
providing the company with cells
for their upcoming line of EV cars.
All up, Wismann claims the Light-
fighter produces 141 horsepower at
6800 rpm with torque measured at
120 lb-ft at 0-6800 rpm (remember
that electric motors make all the
available torque from zero rpm),
and with the gear reduction of 2:1,
makes for a very spicy ride.
The Lightfighter runs a MoTec
CDL3 data logger dash that com-
municates over CAN with the motor
controller itself.
"Between the battery and the
motor is another device—the
inverter. It takes the DC (direct
