Have been changing oil in motorcycles and ATV's for 40+ years and have never used a torque wrench. Never stripped out any threads, lost a drain plug or had one come loose either. Snug the bolt when tightening but do not get hamfisted on it and you should be fine. As per the torque spec it does not take much.
Manufacturers must list specs such as this because they have no desire to warranty stupidity.
