I have recently switched to a 2012 Beta 350 rr. my old bike was a KX 450 I am extremely pleased with the change I race in the A class for a hair scramble series in the southwest lots of tight technical single track along with some desert trail. I have found that the 450 would often tire me out so i started looking at 350s I chose a beta because of the great reviews and opinion. Plus I just couldn't go KTM, I get they are great bikes some have trouble some don't but man everybody and their mother is going to KTM. I am stoked beta to go Beta. So far two rides down and the Difference is amazing as it feels very much like a 250f. amazing power out of that motor! power band good from bottom and screams up top. Excellent motor and chassises fits me great (6'0" 190lbs). It has tons of goodies, thanks guy who sold it, I am hoping for some great results! If you are thinking about the switch, I say go for it you will be pleased!
