Almost all of those suggestions (other than the Street Triple) are lame. Motorbikes for fat middle aged men and women in shapeless black cordura textiles.
Get something with some style:
OP, get a Triumph Bobber. It might well be my next bike.
The only problem with those bikes, is that whilst they look nice in the catalogue when ridden by a bearded hipster with his impossibly photogenic girlfriend* pillion to a coffee stop somewhere in Pembrokeshire, no one in the real world cares.
My dad’s a bit left field and goes on tours with the kind of people who buy those bikes in the real world (other late-middle-aged dads). Only he rides daft stuff like a Bullet, or an Armstrong MT500, a Ural Sidecar outfit, you get the picture. I think he enjoys watching people on shiny new bikes getting more and mere wound up as the inevitable crowd get’s drawn to whatever mad-max looking contraption he’s arrived on.
His latest toy is a D1 bantam (rigid frame), modded for trials, makes the trip to the post box an adventure!
