I'm also looking for my next bike and have been for about 5 years to fair. Having lurked on this forum over those years I got close to buying a couple of Glees, but couldn't bear to part with my trusty TDM 900. Now I've solved the problem by selling both bikes and making myself bikeless.
I've narrowed the field down to either a Honda CB500X, NC750X, Glee or MT07 Tracer. I'm lean, so don't really need anything bigger. Haven't ridden either the CBX or the Glee, so I'm going purely on the hundreds of positive comments on both of those bikes. Took an NC750X out earlier this year and it was fine--and maybe fine is fine as I enter my dotage. It handled well and the power was adequate, though I'd miss the motorway overtake power of the TDM. What attracts me to it is it's reliability, ease of maintenance (less plastic bits, easy valve check, etc.), and the frunk, looks handy. The MT07 Tracer would be the worthy replacement to the TDM except for the poor quality of it's parts. Nothing about it felt robust. I can't see it lasting anywhere near as long as my TDM did--and I'm not Mr spit and polish to be honest. Brilliant bike to ride though, pulls really well, handles great, is economical and just felt so light and easy to manoeuvre, shame about the cheapness of the package. The CB500X, well with it's amazing frugality and the tank range, it's lightness, what's not to like. I think it looks the best of the bunch as well. But will I miss that top end roll-on?
At this stage it's the CB500X or the Glee for me. Did I mention this is a damn good forum, always a big plus.
