I rode the 2015 sherco 300 2stroke a few weeks back. Definitely went quicker than my 2012 300r. I found it very light in the steering compared to my bike, which I didn't like. However this could be something that you could get used to after a few hours. I preferred the factory version to the standard 300. I haven't ridden the beta but have read lots of good reports. One thing I do like is the ease of air box access. Looks like sherco may be going full injection soon.,
