I recently purchased a 2015 superduke 1290r and it is having troubles starting. Most of the time it does not want to start. When you turn the bike on the fuel pump will run and everything turns on like normal.

When you press the starter button it is almost like the starter button is broken as the bike won't even try to turn over most of the time. I took it apart, cleaned it, and tested the continuity. I tested the fuses and all have continuity. I also replaced the starter relay solenoid for a brand new one (just in case that was the problem). I do know the kickstand kill switch sensor has gone bad, but it still doesn't want to start even in neutral with the kickstand up. I also think the neutral sensor is bad because the light will not illuminate on the screen even when in neutral. Is there another sensor or part of wiring that could cause this issue?

Would it be possible for you to take a video with your mobile device and upload to like YouTube to share here? It will help us diagnose.

That said, if its electrical -
  1. If the Kickstand switch is bad, it would not matter of the stand is up and you are in neutral. Think about it - the switch could still be telling the CANBUS system its down.
  2. Have you replaced the battery? 95% of our issues are battery related. It may seem like a strong battery...even test at 12+v at rest...but what is it when you hit the starter? If it drops below I believe 10.5v (someone correct me), it will not start.

If its not electrical..when were the valves last adjusted? These are all things I would consider.
No clue when valves were last adjusted and I tried to start it with a battery charger running to it so it shouldn’t be battery (12.5 volts when trying to start)

@Jacksonpolarbear - And your starter switch button, which you cleaned, DOES indeed have continuity all the way to the relay? (Sounds like you are competent to test this for signal).

My suggestion then would be to push the starter button WHILE moving the handlebars back and forth (just to check for an intermittent broken wire).

Sounds like also you have tested continuity from the starter switch button to at least the plug where the switchgear plugs into the harness. If you have, then maybe it is from that plug to the relay.

What happens if you apply 12v directly to starter solenoid? Does it try to start?
I tested the actual starter button for continuity and it seemed okay. It could definitely be a wire from the starter button though. The old starter relay definitely looked like the previous owner was jumping it from there so I could try that.

I got it to crank by hooking up jumper cables to the battery lol
