For me my bike was always a tool, I commuted by motorcycle for over 30 years and bought bikes that worked with minimal input from me.
VFR’s, Fazer 600, ER5, CBF250, CG125’s, all of those were great, but though I only commuted on my 650 for one year before a job change meant no more daily commute, I’ve found it to be the most useable bike I’ve ever owned.
It’s got a good tank range, is cheap enough on consumables, it’s comfy, has decent weather protection, it’s reliable and has enough umph for most occasions.
I bought mine, a Glee, purely because of it’s useability, but quite like the look of it too.
As others have said, I think the finish would have suffered had I continued commuting (though I always used to paint my bikes with Copperslip in September and not clean it off until April at least, it didn’t look pretty, but worked).
Were I still riding it daily I reckon I’d still be happy, and I still can’t think of anything more useable (maybe a Dullville?).
Only thing I’d do is maybe lower it a touch, compared to your CBF it’s huge, for my occasional use it’s not an issue, but having feet flat on the floor when paddling about in start-stop traffic or shuffling into parking spaces etc is essential in my mind for a daily ride.
The big bonus for me is it turns out the bike is equally capable for the occasional use it gets nowadays. Whether nipping out to the shops, over to the TT, or for a lap of Europe, while others might do it faster or cooler, the 650 really is (these days at least) all the bike I’ll ever need.
If you can get a test ride, I reckon you’ll buy one
