think about a QR skewer on front and rear wheels. anybody use a torque wrench to adjust and latch those? i don't think so. we guess, and say to ourselves "ok, that's good". or something to that effect.

most of us learned to tighten a nut by the time we were ten years old. a couple of stripped threads, rounded off heads, and snapped bolts and we were there.

then there's my brother-in-law who refuses to stop tightening nuts until beads of sweat appear on his forehead.

BTW, least anyone think i regard torque wrenches as useless, i would recommend them for many high performance engine type applications, i.e. head bolts, big end bearing bolts, crankshaft bearing bolts, headers, clutch plates, flywheels and many others. bikes are low stress by comparison.
