Keeping your Cruiser Tight

(What you torquing 'bout Willis?)

Every nut bolt and screw on your Cruiser has a fomulated torque. The torque or tightness can be further limited by the type and material the fastener is made of as well as the object the fastener is being fitted to. The torques listed below are taken from the BMW R1200c repair manual then adjusted by applying the change-over formula supplied by the Handbook of Chemistry and Physics (from Newton-meters to foot pounds).
