It remained largely unchanged through its production. 1991 saw updates with inverted forks added, and 1993 got updates with ram air just a single tube, then in 1996 more updates with twin tube ram air and Tokico six piston brakes and fully adjustable suspension. Between 1989 and 1995 in the US market the ZXR-750 and ZXR-750R were known as ZX-7 and ZX-7R respectively. Starting from 1996 Kawasaki dropped the ZXR name worldwide and the former ZXR-750 was now ZX-7R and the limited edition homologation special ZXR-750R/ZX-7R started in 1991 was now ZX-7RR.[5][6] OverviewThe ZX-7RR was raced, gaining 12 AMA superbike championship victories. Kawasaki's Road Racing team riders were Eric Bostrom, Doug Chandler and Scott Russell. Doug Toland won the 1993 Endurance FIM World Championship. Andreas Hofmann won the 1997 Macau Grand Prix. The ZX-7R has a 749 cc in-line four-cylinder, four-stroke engine. The frame used on the ZX-7R is a lightweight aluminum twin-spar item, designed using computer-aided design to optimize strength. The rear subframe was constructed using steel, providing enough strength for a pillion passenger. The swingarm used largely the same fabrication techniques to produce a hollow cast and pressed aluminum alloy hybrid swingarm, and the Uni-Trak rear suspension system features a predominantly lightweight alloy and aluminum construction. The Uni-Trak system was designed to provide a progressively stiffer damping and spring rate under compression. The rear suspension unit is fully adjustable in terms of damping, preload and compression. The front suspension found on the ZX-7R comprises a fully adjustable 8-way compression and 12-way rebound 43 mm inverted cartridge fork. Front brakes are 320 mm semi-floating front discs and Tokico six-piston calipers. Rear brakes feature a 230 mm disc with a twin-piston opposed caliper. The ZX-7RR differs from the road model with an adjustable head-stock angle, swing arm pivot, additional increased adjustability 28-way compression and 13-way rebound to the front and 14-way rebound for the rear suspension, ten more than the R model, a solo cowl with a different aluminum subframe, and 41 mm flat-slide carburetors versus the 38mm on the base R model. It also has a close ratio gear-box fitted as standard and a crankshaft flywheel that is heavier and Nissin front brake calipers.[1][7] Cycle World got a tested 1/4 mile time of 10.82 seconds at {{Convert|129.68|mph|abbr=on}}.[2]{{multiple image| direction = horizontal | align = left | image1 = Kawasaki ZXR 750.jpeg | width1 = 192 | alt1 = | caption1 = 1989 ZXR-750 tubes that appear to be ram-air, just cooled top of engine. | image2 = Kawasaki Ninja ZX-7 1991 2006KGTW.jpg | width2 = 192 | alt2 = | caption2 = 1991 Kawasaki Ninja ZX-7 | image3 = Kawasaki ZXR 750 R.jpg | width3 = 192 | alt3 = | caption3 = 1992 ZXR-750R }}{{clear}} References1. ^1 {{cite web |url= https://books.google.com/books?id=pCxagksl33AC&pg=RA2-PA43#v=onepage&q&f=false// |magazine=Cycle World |title=1996 Kawasaki ZX-7R |date=March 1996 |pages=43-48 }} 2. ^1 2 {{cite web |url=http://www.cycleworld.com/2013/05/27/superbikes-comparison-test-challenge-review-photos-specifications//|last=Ienatsch |first=Nick |title=Superbikes With Soul: Classic vs. Modern Superbike Comparison Test| magazine=Cycle World|accessdate=October 29, 2016|date=May 27, 2013 }} 3. ^1 2 3 {{Citation |url= http://www.mcnews.com/mcn/technical/2013JanPerfIndx.pdf|title= Performance Index Winter '12/'13 Edition |date=January 2013 |magazine=Motorcycle Consumer News|publisher=Bowtie Magazines |accessdate=}} 4. ^{{cite web |url=http://www.sportrider.com/tech/sportbike-weights-and-measurements//|last= |first= |title=Sportbike Weights and Measurements | magazine=Sport Rider|accessdate=September 18, 2016|date=August 23, 2011 }} 5. ^{{cite web |url=http://www.visordown.com/features/bike-icon-kawasaki-zxr750//|last=Shippey |first=Mark |title=Bike Icon: Kawasaki ZXR750 | publisher=Visor Down|accessdate=April 19, 2017|date=October 10, 2010 }} 6. ^1 {{cite web |url=http://classic-motorbikes.net/kawasaki-zxr750//|title=Kawasaki ZXR750 Road Test| website=Classic-Motorbikes.net|accessdate=April 19, 2017|date=March 7, 2012 }} 7. ^{{cite web |url=http://www.sportrider.com/sr-archive-kawasaki-zx-7rr-road-test-review#page-2//|last=Kunitsugu |first=Kent |title=SR Archive: Kawasaki Zx-7RR Road Test Review| publisher=Sport Rider|accessdate=April 19, 2017|date=January 4, 2017 }} }}{{Refend}}{{Modern Kawasaki motorcycles}}{{DEFAULTSORT:Kawasaki Ninja Zx-7r}} 3 : Kawasaki motorcycles|Sport bikes|Motorcycles introduced in 1995 |
