I only bought the bike a couple of weeks ago from a dealer, so it may not be.
with the ignition off, the battery reads 12v. With the ignition on (engine off) and put under load from the pass light switch, the battery gives a reading of 11v.
Is that normal or would it maybe need a charge/replacing?
A good battery off load should be at least 12.5v. After a good run or charge mine reads 12.8v. See what it drops to when you hit the starter. My battery last year gave me no warning when it failed. I started it as normal and went to get petrol. Came out after paying and when I went to start it, nothing. Wouldn't even bump. Had to push it a mile home. I put a meter across the battery and pressed the starter, nothing and the battery dropped to 9v. Just to make sure it was a duff battery I jumped it off the car and she started straight away. Lifted revs to 3500 and battery voltage was 13.5v so charging system ok. Bought new battery. Problem sorted.
