RULE THE TRACK. RUN THE STREETS. Rule the track and run the streets with legendary Ninja® performance. The Ninja® ZX™-6R motorcycle boasts a potent 636cc engine, advanced electronics, and a lightweight chassis. The “636” has been optimized for both street and the track, offering an exhilarating experience in a wide range of riding situations. Yes you read that right! Only 400 miles from new and in excellent condition! The only visible flaw is a scuff on rear right side tail section, mostly likely a boot scuff while getting onto machine. No freight no prep on this barely used Ninja.
