Engine DesignTwin balancersDesigned for both sports riding and high speed sports touring, the ZZR is, like all ZZRs, very comfortable. Twin engine balancers keep vibration to a minimum. And while the 12R, with its single balancer, uses partial rubber mounting for the engine, the smooth-running ZZR can run rigid engine mounts, for a stiffer, more rigid chassis. Further, use of an oil-pressure cam chain tensioner ensures optimum tension at all times and reduces engine noise. “Since the engine is all-new,” says the project’s leader, “we were able to design it to be not only very powerful, but also so smooth running that it could contribute to chassis performance. The result is a very comfortable high-speed cruising performance.”
