I miss having a bike, but the UK roads really aren't safe enough for them. Well, its not the roads, its the self-centred morons using them.
Not that I ever maxed the ZX-10. Every time I got it up approaching a ton and a half, I kept getting this nagging doubt about it being a (then) 20yr old bike with not a lot holding it together . But the getting from slow to quick was a thrill that's hard to describe, and only those who've ridden a fast bike solo can appreciate.
Miss mine too. Like you, I’m. It sure I trust myself and I certainly don’t trust other road users.
That said, I’m still tempted to get a more cruising type bike of some form (Hornet, Fazer etc)
