ENGINE OIL
If ridden hard the 600RR can use up to a litre of oil every thousand miles, and letting the oil run low leads directly to the early 600RR’S generator and reg/rec issues. That means weekly checks are imperative on a machine seeing regular use. Honda recommend a 10W30 oil for some bikes but 10W40 is fine in all, and much more widely available. Some synthetic oils will give you a slight performance boost, but using a semi-synth is perfectly acceptable. Oils are evolving so quickly that today’s semi-synthetics are as high quality as synthetics from just two years ago. Try Motul’s semi-synth 5100 at £12 per litre, or the fully-synth 300V at £17.
