1973 Kawasaki 903 Z-1 I bought this thing in 1975, after someone had already cut it down for primarily drag racing. The fork springs were cut down 3", rear fender much lower - not a  serious  drag racer but not really a daily rider. I have a timing slip around here somewhere from 'Beeline Dragway' with a 128.30 mph speed - I can't remember the time. But I did, soon after buying it, raise it up to stock height again. I rode it for awhile, then got the XS-E!
