I have a Yamaha SCR950, a KTM 390 Duke and a Yamaha Aerox. I am older than I was, but I have no problem with the weight of the SCR or difficulty changing gears. If the new BMW CE 02 electric motorcycle wasn't so expensive - although I could afford it - I would replace the 390 and Aerox with one. 0-50 KPH is 3 seconds. Decent range. Good suspension, unlike the Aerox. Light. I have worked out how much petrol I use on the KTM and Aerox and projected it over five years. If the batteries went on the CE 04 soon after - they are warranted for five years - the savings on petrol would be swallowed up by the cost of a new batteries. In England,where I am from, the cheaper intial purchase price and bigger saving on petrol - twice as much as Thailand - makes the CE 02 begin to make sense over long-term. Assuming it's reliable.
