Like lots of tools, one torque wrench often proves not to be enough. The rear hub nut on my Ducati needs to be tightened to 170 ft-lbs, which requires a pretty big torque wrench. In contrast, lots of fasteners on bikes have torque specs in inch-lbs. Lug nuts on cars and SUVs often call for a value between 85 and 100 ft-lbs. A lot of home mechanics might get by with 2 torque wrenches to cover the ranges they are most likely to encounter. I have 3, mostly because of that crazy tight nut on the hub of my Ducati. It is also helpful to buy wrenches scaled in newton-meters as well as foot-pounds, since most things not built in the US will will give newton-meter specs. I have conversion scales on my tool box, but the wrenches that have them stamped on are convenient.
