CON.ROD TRIUMPH T90 350
Connecting rod for the Triumph T90 350 unit twin, fitted between crankshaft and piston in the bottom end.
70-6964 is a connecting rod for the Triumph T90 350, the small unit twin that shared its bottom end architecture with the 3TA. The rod lives in the crankcase between the crankshaft and the piston, doing the basic job every con rod does: it transfers the piston's up-and-down motion into the crankshaft's rotation, and it takes the full brunt of every combustion pulse doing it.
