Also, the zx-6R is more of a racing style bike, hence the "R". It has a more tuned suspension, more HP, and a more forward seat position. In contrast the zx-6, or zx-6E is more of a sport cruiser. It has a lower ride height, more upright riding position, a single seat, weighs alittle more and has a softer suspension and brakes. Don't get me wrong, its a good bike. In fact I have both of them at the moment...I'm looking to sell the 6E. in comparison, I personally think my "E" has a little more punch off the line; however, it has full Ti muzzys and jet kit while my "r" does not. Both are very good bikes. Hope this helps some.
You keep campaining for that ass-whooping you might get elected
