I have a acquired the Givi monolock case carrier and the case monolock e450 on last friday (29july). The first impression of it its positive. it�s good to ride without no weight in my back, to keep the helmet in the box (one or two), to be able to ride at the supermarket to by small stuff... lots of things...

it wasnt i who mounted it but i supose it�s not very dificult because it took about 5 minutes. there is no need to make holes or change any aspect, its quite nice and not high.

The e450 case can take 2 helmets and its functional, the negative point is for the 3 kilos maximum load. of course you can put more but its on your responsability. The ideal case is the e470 but is also a bit more expensive of course.

if anyone want some photos i will provide them in the future.
