So I've been going insane, trying to decide between a cb500f and cb650f as my first road bike. Test rode both today, expecting to just know which one suited best. Sigh... loved them both, still unsure. Anyone care to advise? cb500f pros: fuel economy, cheaper to buy, super easy as to ride, seems powerful enough. cb650f pros: won't need to upgrade anytime, more powerful, very stable & capable on highway, love the colour scheme. Primarily for commuting with occasional weekend blast, 40 year old who just wants a bike that I won't need to upgrade in 12 mths time. No licence restrictions. Did really enjoy the no fuss torque of the 500. Does anyone ever keep a LAMS bike when they don't need to or does everyone get the bug and crave more power? How much more expensive to run would a 4cyl 650 be over the 500, particularly chain/sprockets/tyres ?
