Nice topic Telbert. I've owned multiple British, Italian and BMW motorcycles, but alas only ridden KTM's; particularly enjoying the SMT, so the new 1190 Adventure must be fun. I've also been to most of the UK race tracks, ridden on many, owned inline 4's, triples, twins, two-strokes and ridden six cylinder bikes too. So getting a few ticks sorted on the list bike wise. I think my oustanding ticks are more related to specific rides. I'd still like to ride:
1) Stelvio Pass
2) Blue Ridge Parkway (full length)
3) Highway 1
I've ridden in the Pyrenees, and on the Cherohala Skyway and the Deal's Gap Dragon. They're probably my favourite rides, along with the best that England and Wales have to offer, in the B660 (Bedford to Kimbolton section) and A483 Newtown to Builth Wells. If you get the chance to ride any of those, then you're a very lucky biker indeed!
