I forgot about the GSXR1100 - I rode one of the originals. It had a dead coil, so was missing a cylinder, and it still scared the crap out of me.
When I was 14, my dad had a Kawasaki 3 lunger - I think it was a KZ700 or 750. I also remember having to ride the crap out of it, and keep hot plugs, or it would foul them. Heavy bike, but fast. Peaky though - dead on the bottom end, but when it hit the power band, BAM!. It had a damper, like a shock absorber, on the steering to try to keep that wobble under control.
I shouldn't have been riding it. At 14. At 110+ MPH. On all the highways around our farm. But I did, I'm alive, and it was tremendous fun.
The GPZ750 turbo and GPZ 1100 were also popular. As I recall, performance of the two was almost identical.
Does anyone remember something called I think a Seca turbo? Yamaha, I think.
