The ride is comfortable, and the rear seat too?

“The YZF-R15 and FZ16 engines have a single-axis balancer. This reduces engine vibration, which in turn reduces vibration felt by the riders at the front and rear of the seat, the handlebars and the footrest.”“Also the reduced engine vibration means that the engine can be mounted to the frame without rubber mounts to make for a sturdier frame. The sturdier frame is one of the keys to the sharper sportier ride these models have.”
