i have the baby bro to the z1k, a 2006 z750s.
it has been a rock solid, very fun ride for the 10 months/3k miles i have owned it.
after not riding for 35 years, the z750s was exactly what i needed.
i use the bike to commute into manhattan 2-3 times a week and do solo runs up and back into the hudson valley north of nyc.
if i could figure out how to post pictures, i'd share some very unprofessional pix.
(southwade has REALLY raised the bar on z1k pix!)
