calipers (the same as on the first-generation Ducati
Panigale V4 S of 2018). These are squeezed by a
Brembo 19 RCS Corsa Corta master-cylinder. Out
back, there's a 230mm fully-floating disc mated to
a Brembo two-piston caliper. Being a racer, there's
no ABS to worry about. Tires come curtesy of a
Pirelli Diablo Superbike SC1 NHS 120/70 ZR17
up front and a Pirelli Diablo Superbike SC1 NHS
180/60 ZR17 in the back.
One of the big talking points with any Kramer is
the gas tank. Instead of using the tank in the tradi-
tional place behind the steering head, the 4.3-gal-
lon gas tank, subframe and rider seat are all one
unit. There's no steel bracketry, no extra mounting
or weight. Superbike and GP teams have known
for years the best place to have the gas tank is not
high up like a traditional tank but lower in the chas-
sis. The Kramer design allows for weight distribu-
tion to be better maintained as the race wears on
and the fuel load goes down.
With a full tank of gas, the Kramer GP2-890R
weighs a stunning 330 pounds, ready to race.
Kramer teamed up with AiM to for the 890 ver-
sion, using the British company's very trick dash
that displays most data any racer would want.
The AiM dash allows you to download your
data such as lap times and all of your telemetry
data that you'd expect through the standard AiM
software, like throttle position, brake pressure,
GPS location, accelerometer, G-force, etc.," says
Karvonen. The AiM dash makes this thing a proper
racebike. The 890 Duke is a great bike. It's a hard
thing to make better, but we feel like we did that."
The electronics are still a bit of a work in prog-
ress. Kramer will be providing traction control in
the future with each GP2, but as of right now it's
not available. Other than that, each GP2 comes
with two engine maps (one for wet, one for dry), as
well as two engine braking maps. This is one area
potential customers will want sorted before they go
