Hi. Do someone here know about a compatible aluminum tube for the first Multistrada 1200? I found just the G2 Ergo that comes from the US and is a bit pricey. If I remember correctly the stock throttle control is a Domino unit, the same kind used on many off road bikes, a compatibility should be easier to find... I guess! Off road bikes have 30/40 euros tubes to choose from, and even some interesting model that comes with bearings. The problem is to find this compatibility, as first thing. Thank you very much
