Set of TRS pins. Unknown what bike they go to, but my best guess is a CBR600 Pin#1 DIA = 0.75" Pin #2 DIA = 0.54" $50+ shipping
There’s a code on the end of the pins and this chart will show what they fit https://www.pit-bull.com/pdf/fitting_chart_trs.pdf?
There are letters/numbers stamped into the end of each pin Example “BL” or “BR” that’s all anyone needs to figure out what bike they work on
