because its not a sportbike. anyhtign that has R in the title is considered a sport bike.
also insurance companies know CBR, GSXR, R6, ZX6R
the 919 is more of a sport touring style bike with its upright riding position.
as long as your not trying to keep up with the crotch rockets, the bike will be great for you.
i personally love the bike. it has the old CBR900RR motor on it, and it will shit and get. but its nothing in comparison to a new cbr600RRand especially the cbr1000RR. but call and check ins on the 600RR and the 919. youll be surprised of the price difference.
