Vehicle1988 Yamaha FZR 400
Sexy ass bike!
MotorAdvanced DC A00-4009 Series Wound DC
Rated for 36 volts running at 72 volts
350 amps peak
DrivetrainElectric direct drive
ControllerAlltrax 7245
72 volt 450 amp peak controller. The Batteries are the limiting factor right now the controller and motor can take alot more then they can dish out.
Batteries6 Interstate 35 amp/h power patrol, 12.00 Volt, Lead-Acid, AGM
Seem to be holding up quite well. I can pull about 300 amps before the voltage falls to 60 volts. I consider below 64 volts the danger zone. These batteries are doing fine although they are not high power. I plan on upgrading to hawkers when these ones wear out...
System Voltage72 Volts
ChargerSoneil 1206
12 volt 3 amp smart chargers (6 of them 1 for each battery) + a 1 amp charger for accessory battery.1 of them recently overheated and started charging funny so i replaced it and installed a fan to keep them cool. I also discovered that by opening them up you can adjust the voltage output with a little turn screw inside. So i adjusted them to the voltage level i wanted and then epoxied the turn screw so it wouldn't move...
DC/DC Converter none
using 12 volt auxiliary battery. Charged by separate 1amp charger.
InstrumentationPaktrakr
monitors each individual battery voltage as well as temperature, amps, and a load of other cool graphs
Top Speed66 MPH (106 KPH)
tops out at about 105km/h looks like i geared it perfect. 15 tooth in the front 55 tooth in the back.
AccelerationDid one test run feels great! Estimated 0-60 about 5 seconds... this is while sagging batteries to lower then you should for long life. Accelerating to 60mph without bringing the voltage into the danger zone is more like 9-10 secs.
Range14 Miles (22 Kilometers)
I have driven 13 Kms at high speed
(90km/h for 6 kms and 80km/h for the 6 kms back + 1km in town) and the batteries were starting to feel it in the last couple of KMs. The voltage started to sag quite a bit so i was careful in the last couple kms... Around town i can easily get 20Km to a charge.
Watt Hours/Mile125 Wh/Mile
Unconfirmed. Based on other similar conversions. Thats also what my estimated range is based on.


Values below in the miles box are KMs...
EV Miles
Start:27,270 Miles (43,877 Kilometers)
Current:27,933 Miles (44,944 Kilometers)
Total:663 Miles (1,066 Kilometers)
Seating Capacity1, but if your really friendly 2, or maybe even 3 if your too friendly...
Curb Weight400 Pounds (181 Kilograms)
Unconfirmed



TiresStandard. I replaced the old rear tire but not before destroying it with a few burnouts... See you tube
Conversion Timeto many hours to count don't really know!!
Conversion Cost$4000 CDN about
Additional FeaturesSpilled black oil and neon green coolant during the ICE removal. Cool color! Large red keyed safety switch used to activate pre-charge circuit and when pre-charged, you turn the main key to activate the contactor. Made very few frame modifications to accommodate the motor and batteries.
Had fun building this bike with my friend and would like to thank my friends and my family for helping me out on this project!!
