Although it’s not a fire-breather or a class leader in any category, the RM-Z450′s engine isn’t at the bottom of the class either. It makes good torque, is responsive enough off the bottom, and revs just high enough to not feel flat. The addition of the MX-Tuner 2.0 system allows user customization of engine characteristics, which in turn help riders build a powerband to best suit their needs. Shifting is smooth and clutch fade is minimal, but the biggest drawback of the RM-Z450 engine is no secret; it still lacks electric start. It does start on the first kick almost every time, but an electric start option would be worth a small increase in price.
