Smiths Trip Reset Knob LONG Triumph BSA Norton Ducati 650 750 Ducati Exhaust later TRICOR numbers are 60-0982A beautiful new part, stainless steel. This is the LONGER of the two styles made, to suit the 3" magnetic Smiths gauges installed on just about every British motorcycle (and some Italian) after 1964. Overall length of the knob is about 2", meant for gauges with adjustment from UNDERNEATH the instrument body, as with most Norton. It will also work for the more common 'side' location, but it's a little long.
