There is no risk to your UK license. The worst case scenario is that you get a ban in that country and can't ride/drive there for the period of the ban. It's not Switzerland so you'd have to be going at significant speed to attract a ban.
The fine may or may not be forwarded to your UK address. The DVLA are happy to share the details of UK registered vehicles if the local authorities can be bothered to ask, and then be bothered forward the fine to you in the UK.
However, the way to look at it is, if you were offered, for a charge equal to the value of the fine, to be able to ride the road at the speed you did, would you accept that charge? If the answer is yes, and I think for most of us on here it would likely be yes, then that's what you're paying.
