http://www.enduro360.com/2014/10/08/products-tested/2015-beta-430rr-first-review-2/ We were on the same Baja Mex trail ride, the bike is striking in the sunshine, it's very Italian.

Wearing a 6d helmet, want to see the review of that. Beta really seems to be Huskys replacment for the people that don't care for ktm. Really love the look of them.
Beta 4Ts to me as I mentioned before are the evolution of the 450/510 series of dual cammers, these Betas are well evolved versions of those models and even more refined and further engineered.
The part of the write up pertaining to fit and finish is spot on. You really have to throw a leg over one to appreciate them. The local dealer by me is totally behind the brand. So much so that he started racing again after several years off because he thought he was getting too old. Turns out he just hadn't had the right bike according to him.
