Remember guys and gals. These bikes competed in the ISDT (ISDE). I cant think of any thing harder than pulling high rpms to get through/over obstacles, then going slow over technical sections for long periods. Riding enduros on 4 stroke aircooled dirt bikes has often left me in awe of what an aircooled engine can withstand and happily fire up and do it again.
Being an ex Californian living in "progressive" WA state. Don't get me going on lane splitting. These people will kill you to prove a point. Be careful if you're not used to the retaliation that comes with it.
