One thing I appreciate about Brammo is that they are selecting top-quality suspension components for their models. The shock and forks on my Zero are made by Fast Ace, a Taiwanese manufacturer (I believe). While they are fully adjustable and light, they seemed to have been designed for the mini-motocross crowd and I am not overly impressed with their performance on the street. No doubt they are cheap and light, though.
Also, while the Hayes (an American company) brake components on the Zero are OK, they are not Brembo quality, do not function as well and are not supported by the aftermarket (such for brake pads) to anywhere near the extent as Brembo.
I just wanted to give Brammo a pat on the back for not cutting corners on their chassis components.
