I had a chat with the salesman about the 790 vs the 890. He thinks that for most people, and that definitely includes me, the £3,000 difference isn't worth paying. For road use the 790 is plenty and that £3k buys a fair few farkles, tyres and a lot of petrol. I'm simply not a good enough rider to benefit from the 890. I don't need the extra power and wouldn't use it. Mind you, if money was no object, I might have gone for the 890 just because I could.
