I own a few torque wrenches, due to needing them on my car. If you get one you can find some fairly inexpensive ones, maybe not park or craftsmen which I do like both brands. Torque wrench if going between those brands i would go craftsman simple due to the lifetime warranty which they honer without any problems. But everyone is right, I have not used one on my bike yet, mainly do to I don't have the allen wrenches for the torque wrench yet. Just don't do the mistake I made once on my car, use a ft .lbs torque wrench instead of teh inch .lbs you will strip out a bolt.. (took forever to get a replacement bolt for my valve cover on my car)..

It is something you will use once a month at best.. better off using that money eleswhere unless you find one fairly cheap..
