is 70 miles a day too much ?

[Lumpy]

mine doesn't get washed very much at all. Stainless downpipes and a Fazer thou caliper have helped no end to stave off the excesses of the weather. Mine does at least 250 miles per week, normally more, in all weathers including snow unless completely unrideable. Do wash the salt off with cold water though just to give her a chance. No corrosion problems if ACF 50 is used in certain areas.

darrsi is the chap to ask, he knows everything after 25 years riding  :evil
