Motorcycle Questions? Ask a Mechanic.
Does the bike turn over? If so, the security system is not the issue.
Have there been any recent modifications?
Do you have the security fobs? If they aren't working then the first thing to do is to change the battery in a fob. This is the most common issue with them not communicating with the security system to disarm it.
If you don't have the security fobs you will need to know the PIN. If you know it I can help walk you through the input of it.
There is no other way to bypass the system without an HD or aftermarket service computer.
