ahhhh..... i have aslo had a bit of a love hate relationship with 500/550 strange. had a k3 and a 500 years ago thats why i got my 500. mixed memories of them. lots of fun but also a major injury on the back of a friends 550. Broken leg (plated) broken arm, concussion, damaged back, and lots of skin gone on my bum. ouch_... 550 centre stands dig in to early and at 80mph that hurts.( he lost his leg) but still have a soft spot for them. think it is the simplicity and lines when altered a little. Good to see so many are still around.
