The problem revolves around the fact that Agusta didn't see fit to appoint a weight engineer to review the changes from the A109A2 model. Hence you have the trailing link on the undercarriage (for example) made of stainless steel. Which is a laudable idea for durability but adds weight.
And just about everything within the design was 'beefed up' so the weight grew (and grew). Panels that were .020" became .032", and one element you could look at would be the plethroa of ' electrical provisions' built in with multi-pin plugs and sockets just everywhere. 'Many a mickle makes a muckle' as they say. You would be amazed at the cumulative effect of all these minimal weight increases. (I tackled a new machine on delivery and managed to remove some 25kg of redundant wiring and connectors. Huge amount of work = labour = much money)
And finally the interior(s). If your machine has the 'silent' one, it has lead sheeting sandwiched in the beautiful (and heavy) custom leather trim, to attenuate the Xmsn noise in the cabin. And very effective too. But one hell of a penalty to payload
