Dammn just bought one for 138 euro's ;-))) and a cheap chinesium for 20 euro's as a spare under the 900 ss seat since I got stranded last week with a blown R/R after 67.000 km
The one in the photo doesn’t look like any of the MOSFET one’s I have seen before. They all look like the one in the first post.

For even cooler running than mosfet have a look at the Series R/R from Electrex. I ran one on my 1198S.
