R&G are the best place to start - I have "crash tested" their stuff. It works.
don't waste money on the one for the front spindle - the tuono doesn't need them it's got proper handlebars rather than clip-ons.
The front upper ones are good at low speed stuff - save your radiators if you topple etc.
The Rear Frame mounted ones - rear engine mounting REALLY do the business holding the bike off the tarmac at road legal speeds.
Replace the cotton bobbins to protect the swing arm etc.
Replace the bar ends if you want to.
If you crash above 60/70 then the bike will most likely flip at some point and destroy itself beyond any crash bung.
R&G will send the stuff out pretty much same day, and you can buy individual parts to sort them if you have a minor off.
Or of course you can make your own, I think Blue Peter do some made out of old toilet tubes and yoghurt pots.:rolleyes
