I have one of
these, which will do 10-80Nm - good kit at a fair price. Will do everything on the bike except the steering stem nut, swingarm pivot bolt and rear axle nut. I have a bigger 1/2" drive one for these that I've had for donkey's years. There is, as mentioned, a few 5 and 7Nm fasteners, but I've always done them by "feel".
Adapters are always handy, but remember, the more links (adapters, extention bars etc) you put between the torque wrench and the nut/bolt, the less accurate it will be (especially when the torque setting is very low) and never use a universal joint adapter or wobble bar, as you'll end up miles out.
