I have my 450ES in getting fixed for electric shift problems.The problem is when I drive in 4th or 5th for any length of time I can't shift up or down without first stopping then turning the key "off" then "on" after that I can shift down to "N" start the bike again .The dealer has it now and has tried the following;
New speed sensor
New angle sensor
cleaned the electric shift motor
checked the thumb shifter
They dont know what next so there it sits.Does Anyone have any futher ideas......I need my bike back[img]i/expressions/face-icon-small-sad.gif[/img]

 

My second 450es I got 2 weeks ago worked perfect until Friday Night. I had that happen as well as the 4x4 light flashing, lost odometer& speedometer.

I found the "temp" solution that you did right away. I then figured out that if I gave it less than 1/4 throttle it worked fine. That got me out of the woods [img]i/expressions/face-icon-small-smile.gif[/img]
Saturday morning I took it the dealer who put a new speed sensor on it. It works fine again. I hope that that solves the problem because I am heading across Newfoundland twice starting next week!

I hop this helps,
