No, because at the ends of the scale, a torque wrench could be off by almost 20%. Also there are many bolts on your bike that require 12 Lbs ft or less of torque. That's why you need at least two wrenches. And one should be a Lbs In wrench.
One more thing about click type wrenches. When using it on a very low torque aplication, I always set the wrench, then put it on a larger bolt to click it a couple of times and it is set. Sometimes, if you don't do that, the wrench will not click when it should and you will over tighten the first bolt. This is really bad for small bolts that go into aluminum. This is true of any click type wrench regardless of how much you payed for it.
