If it's an SP then it's a piece of pudding. Could probably be done in under 10 minutes if you had to.

R spec is a different kettle of bananas. Will take longer as you'll need to drain the oil (and water), or tip the bike over on it's side if you're a tight arse as the cover needs to come off, so will probably require a new gasket as well.

On the SP, once you've got the fairing out the way all you need is 10mm T bar, and a torque wrench with a 10mm socket. Oh and maybe a couple of pokeys to pick the plates out.

R is pretty much the same in the way of tools. Nothing special required.
