Would not be good for early K-bikes (don't know about others) as the valve cover bolts are 6.5 ft/lb. The HF wrenches are marked in Nm and in/lb or Nm and ft/lb on the same wrench. No conversion needed.
That looks very much like one of my torque wrenches and you are right Lee, I don't use that one on my old K, but I do use it occasionally on my R1100.
Retired and riding my RTs, the '87 K100 & the '98 R1100 !
