Hi Stavros, I did too sold my 57 plate FJR and bought the MT-09. Wow what a diffrence you are going to notice.
The MT feels like a little 125cc bike in comparison. Turns in quicker, much easier to handle in traffic and filter with and obviously more fun.
On the rare occasion I do miss the FJR, but it's rare, like when it's howling of rain and really really cold.
But I don't plan on doing 3/500 mile days and the mt suits me much better now.
The plus point for me is how light it is, I can actually push the bike about without giving myself a hernia!!!!!
