Bombardier finally came out with a nice 450 racer.
I really like the overall look of it and seems like it has "best in class" everything. Lighter chassis,more power, more travel, etc.
Powered by the Rotax like most people figured. I think if I were looking for a new quad, this would be on the top of my list, right next to the KTM.
