BMW F650GS’s F800 series-derived twin is a sweetie. Softer cams trade off peak power for a more gentle and progressive power delivery (and a learner-friendly 34bhp version is also available at no extra cost). The result is peak power is down from 85bhp to a still more-than-useful 71bhp and with a healthy wodge of more low-down grunt. It’s both flexible and novice-friendly, yet with top end to be truly versatile.
