Rumour has it that Guzzi is working on an " adventure tourer " .
I think the Breva is a good bike to start your conversion , it wouldn't really need much apart from some decent bags , a bit of suspension work and a set of dual sport tyres .You might want to change the front wheel to a 19 inch for rougher roads .
It is a bit low on power for 2 up touring though [ IMHO ] .
Guards can be fabricated to cover the vulnerable bits ,make 'em out of cardboard and then trot along to a good welder and have 'em fabricated out of aluminum ,they will probably be cheaper than Touratech .
If you are a Guzzi enthusiast you will have a great time doing the conversion and have a unique bike .
