Lambda sensor replacement

[AusVeloce]

Hi all, long time no post.

I am looking for a replacement lambda sensor for a 2008 Corsaro Veloce. Haven't had any luck sourcing a OEM NGK OZA591-BB2 which appear to be no longer available. Thought I had sourced an alternative from an Italian supplier that listed it as suitable for my bike (4 pin lambda was 45 euro + 100 euro postage, ouch) but when it arrived it was a 2 pin unit that doesn't fit and I am currently arguing over the refund but that's another story. Does anyone know if there is another suitable unit available that would plug straight in eg Ducati or Guzzi maybe?
