2014 BMW R NineT (Classic)
FWIW I ended up fitting an oil cooler guard as some of you might have seen in my modifications thread. Certainly in Scotland temps NEVER make it really high even in mid summer - normally might just get to the mid 80F bracket on a really hot day. In my case at least I've not had any issues whatsoever. I provided the original information in good faith and I reiterate that it is up to the reader to make up their own minds as to if an oil cooler guard should be fitted or not.
