Too great. Almost 100% traction, can punch the throttle repeatedly with no ill effects. I see that Dx1 has been roughly halved in the MX tires. Does this have something to do with the added knob/bulldozing lines at the bottom of the file? Is there any explanation of these added lines and any other tire changes that have been made? Trying to get a dirt track bike figured out, but the tire is kicking my ass right now.
