Sports bikes usually starts with 500cc plus. A 250 cc bike is not even allowed on highway here.
and literally all 600 cc bikes are or close to 400 pounds. So no exaggeration there. 
and I repeat: There is NO way, a rider will fall and be able to get up and pick up the bike and will go on !! No way. Faris Udeen will confirm it for you or anyone who have had a sports bike.
