|Location||Cordova, Tennessee US map|
|Vehicle||1984 Kawasaki GPz 900R / ZX900A |
This bike has not been running for a number of years and appears to have been stored outside for the majority of that time. The engine block has a baseball size hole in it from a rouge connecting rod. Most of the other parts, including the ones I need for the conversion, are in reasonable shape though.
|Motor|| AC-20 3-Phase AC|
54lb (24.5kg) 40kw peak (54hp) 89% peak efficiency
|Drivetrain||Single, direct 5:1(13:65) reduction 530 chain drive|
|Batteries||124 Headway 40152S, 99.20 Volt, Lithium Iron Phosphate|
3.2V 15ah cells 480g ea. ~100w*hr/kg
Over 1000 W/kg
31s4p configuration for 99v nominal at 60ah for ~5.9kw*hr nominal.
131lb (59.52kg) pack weight
|System Voltage||96 Volts|
|Top Speed||112 MPH (180 KPH)|
Gearing limited to 112mph. With a 5:1 ratio and 18" wheel, the motor is kept at peak efficiency between 45-65mph (72-104kph) which is inline with local speed limits. I do not plan on much highway use.
|Acceleration||Should be nice with the 5:1 ratio|
Calculations say 0-60mph in ~5sec
|Range||60 Miles (96 Kilometers)|
Calculators say 50-60mi avg. to 80% discharge
40-80mi depending on speed
|Seating Capacity||2 adults|
|Curb Weight||420 Pounds (190 Kilograms)|
Should be 420lb or lighter.
Was ~566lb (257kg) stock and wet.
|Tires||Will be Michelin Pilot Activ|
Front: 120/80-16 60 V
Rear: 130/80-18 66 V
|Conversion Time||As fast as funds permit. Started April 21, 2012|
|Conversion Cost||Looking like ~$8000 in the end.|
Bike + shipping: $914.93
Magura throttle w/ dummy grip: $57
Motor and controller: $1950 + $130 shipping
|Additional Features||The bike will have full LED lighting, regen as a rear brake and on board charging. Enhanced air cooling for the motor will be in the works once the bike is "finished".|
|(May 17 2012): I have the bike down to a rolling chassis now. I am currently working on getting the main frame repainted, the suspension and brakes refurbished and the motor mounts finalized.|
(May 26 2012): Main frame re-painted. Considering battery voltage increase to 145v-158v with 44-48s. Supposedly higher voltages are okay on the ME0913 especially considering max rpm will coincide with max speed. Which at 80+mph will neither be frequent or sustained.
(December 4 2012): Received the motor and controller from the 2012 ARC-EV race bike with a couple custom controller features and a fiberglass airscoop. It will be a substantial improvement in power handling and heat tolerance over the ME0913 which I will sell shortly.
