Vehicle1994 Suzuki GSX-R 1100
This was a '94 GSX-R 1100 rolling
chassis that I bought off of e-bay.
These have a large and square main
frame for motor and batteries. It
arrived in about 1000 pieces, which
I've been slowly putting back together
over the last 8 months.

Inicdentally, GSX-R stands for Grand
Sport eXperimtal - Racing. I replaced
Racing with Electric...which made it
sex-E.
MotorHPEVS AC-20 3-Phase AC
Converted to AC from a D&D series. Series
motor was nice, but AC has a much wider
power band and regen.
DrivetrainDirect chain drive 4.7:1. 52 tooth rear,
11
front.
ControllerCurtis 1238-7601
650A, AC
Batteries24 other GBS, 3.60 Volt, Lithium Iron Phosphate
GBS LiFePO4 from Elite power solutions.

They rate the set up at 60 Ah, 87 V
max, 76 nominal. Integrated BMS.

The wider battery packs that bulge out
near the front are suggestive of the
inline-4 from the original GSX-R.

Top Speed80 MPH (128 KPH)
I've had it over 80 mph. Probably capable
of over 100 mph with lower gearing. 80 is
plenty for me.
AccelerationFast...need to time it, but 0-60 in under
6 sec I'm guessing.
Range30 Miles (48 Kilometers)
Depends on speeds and throttle usage.
Easier accelerations and lower speeds give
me up to 50 mi.

Curb Weight420 Pounds (190 Kilograms)
About 60 lb lighter than the original ICE
GSX-R 1100.

Conversion TimeSo far, about 18 months...just finished
the AC conversion Jan 2012.
Conversion CostI've pretty much lost track, but I
estimate about $9000 invested.
Additional FeaturesI've pretty much rebuilt this entire bike from the ground
up. It came in about 1000 pieces, many of which didn't
even match. I spent hundreds of $$ on new parts, paint,
more parts, more paint...

Custom headlight, taillights, turns, stripped everything
down and repainted...fabricated the motor mount,
headlight bracket, indicator lights, shaved the subframe
and recovered the seat...after market lower fairing,
mirror...

Anyway...describing all the custom fabricated and
machined parts is too much for here. Please check out my
web-page. I've done everything myself, either in my
garage or in the machine shop where I work.
This thing has been a chameleon for the last 18 months. I
haven't been able to afford the motor and batteries until
just recently, so I just keep changing things on the
style side.

It's actually given me a lot of time to work on the bike
itself. Been a lot of fun tweaking the design, trying to
get it just the way I want it. If I'd had the money for
the conversion right away, I would have just built it
without all the custom work.

I view building this bike as functional art. My
inspiration comes from a mix of modern street-fighters,
cafe-racers, and old school bobbers (emphasized by the
flat-black with red wheels and brushed aluminum). And a
little pimpin' gold around the edges.

I have to put in a shout out for the Jacob Smith who is
building el-Gixxer. That's how I decided to get a 93-95
era GSX-R chassis. It's like that frame was MADE to be
converted to electric. Thanks Jacob (and Suzuki).
