Odometer reset knob for many Nippon Seiki speedometers, usually fitted to early Yamaha & Suzuki motorcycles. The clocks shown in the photo are for the Yamaha RD250A/RD350A models & the Suzuki GT380 >550, please note this will not fit clocks manufactured by Nippon Denso. This is a re-manufactured part (3 D printed) as such it may not exactly match the original item but it is a very close copy of the Yamaha unit, as they are 3D printed they may show one or two slight imperfections which is quite normal with 3D prints. The Suzuki knob may have a different profile but this replacement will still work. Supplied with a holding screw, will fit 4mm shafts with pre-drilled screw hole, see photos. Length is 27.5mm. This will not fit the later left hand threaded clocks such as those fitted to the RD400 or clocks which do not have the centre holding screw.
