Here is one at a sensible price https://www.ebay.co.uk/itm/125558669608?...R7ai2YX6YA
You will need this eventually, and a bargain at £27. New one from those thieving swine at Suzuki is £156!

Bought it. Doesn't look so hard to make, so maybe I copy it.

I got mine from Hessler and that was about 55 EUR. The ebay one is a bargain and looks basically the same!
