Conversion Time~80 hours so far.
Conversion CostBike was $1000, however I sold ex250 engine for $700. About $2.5k for motor, controller, 1.2K for batteries and accessories. Just over 3k total, I far!
The Ninja 250 is a very good bike to convert. Light weight, good brakes and shocks, plentiful parts on ebay, fairing to hide everything. 1/09 Changed the Mars 709 motor to the Agni #95R reinforced. 4/8/11 Changed out the AGM's for Calb Lifepo4's...lost 70lbs and doubled range. 7/15 changed the Calbs for 11 Leaf modules and Alltrax controller
