I have just bought a 998s Japanese import. I got advice on the forum for what to look for. Other than the bike being in KPH I couldn't find anything else on my bike that would make it different to a UK 998s.
I wasn’t sure whether they were similar to the US models in Japan. What are some of the differences you mention to look out for?
Here is the thread I started. Everything is in it that I asked: https://www.ducatiforum.co.uk/threads/998s-japan-import.73161/
