Vehicle1996 Yamaha FZR 600
The fairing is red, gray, and black. It is also bent and busted
from being laid over. I may not end up using all of it.
MotorMars ME0708 Permanent Magnet DC
Front sprocket is a 13T and the rear sprocket is a 68T. That
puts the gear ration at 1:5.23. People recommend that the
ratio be between 1:5 and 1:6. This ration should work well.
ControllerAlltrax 4844 400 amp (scaled back to 300 amps)
Batteries4 Will Power Deep Cycle 90Ah, 48.00 Volt, Lead-Acid, Flooded
The 4 deep cycle batteries from the south Topeka Battery are
going to be used to power the motor. Another 12 volt
battery will be used to power just the lights.
System Voltage48 Volts
Charger NOCO 12-48 Volt, 40 Amp Genius 4 Bank Charger
The great thing about this one is that it can charge the 4
batteries even when they are wired in a series. It has been installed and maintains the batteries individually. It has been a great charger so far!
DC/DC Converter
Instead of a DC/DC converter, I'll probably use a 5th
battery just for the electronics.
InstrumentationA cheap volt meter from Harbor Freight.
Top Speed45 MPH (72 KPH)
This bike will get going. It was a little slow on the start
with a rear 45T sprocket. With the 68T, it should
accelerate much better or it could just be slow off the
start because I'm a big boy. With the 13T drive sprocket
and a 45T driven sprocket it was able to get up to 55
MPH. I still need to test the top speed with a 13T/68T
combination. I'm hoping for about 45 MPH.
AccelerationThis bike gets going pretty well with 13T/45T sprockets.
With 13T/68T combination, it should get going a little faster.
It doesn't have the quick off-the-line like the electric race
bikes on youtube, but it does the job.
Range12 Miles (19 Kilometers)
The batteries have been charged a few times and I think
I've gone about 30 or so miles so far. I've driven to our
church a couple of times and a few 5+ mile road trips
around my neighborhood.

Curb Weight0
I want to get the bike weighed at the recycling center since
they have a scale on to which I can drive.
TiresFront Tire Size - 110/70 R17
Rear Tire Size - 140/60 R18
Conversion TimeThis conversion is still on-going but to get the bike into a
rideable state took about 1 month which was spent mostly
waiting for parts and building battery racks.
Conversion CostAbout $1,700 to get it rideable. Somewhere around $2,000
now. There is still some work to be done on the lighting and
fairing so it will go up a little more.
This bike was purchased without a motor. The fairing was off but it was there. I have
been working on this bike since March 29, 2010.

Future items: add a battery monitoring system that monitors the batteries as a
combined total and individually.
