In 1982, Kawasaki built 29 examples of the KZ1000S1, a damn good copy of the previous year’s race bike campaigned by Eddie Lawson. They were only made available to the factory race team and any American dealerships that sponsored Superbike teams. The public had to settle for the still-very-cool KZ1000 ELR.
This example (VIN: JKAKZCR15CA000080) was originally sold out of a Kawasaki dealership in Tucson, Arizona and it’s being offered by the second owner. The original owner replaced the original slick tires with Dunlop street tires and the Keihin CR carbs with 33mm Mikuni smoothbores (the originals have since been re-installed). The seller claims that this bike has just 100 miles and it comes with an impressive amount of paperwork – chassis and engine manuals, dealer information sheet, chassis and engine part pricing books, and more. The seller acquired it in January of this year. There’s additional documentation in this Facebook thread, including an invoice from Kawasaki USA to the dealership in Tucson. Back in 2013, an example with an extensive amount of spares sold on eBay for $107,200.
