The new R1 maintains the same liquid-cooled 4-stroke, DOHC, 40 degree forward-inclined, 4-cylinder and 5-valve fuel injected engine format. But a new-design combustion chamber, high-lift cams and 12.4:1 compression ratio has increased intake/exhaust efficiency for a significant boost in power output. A smoother intake port shape has also increased intake air volume. Max power has been raised by 3bhp to 175bhp at the same rpm level of 12,500 rpm (or 183bhp with ram air effect).
