Actually. the majority of the Japanese sportbikes (Honda, Suzuki, Kawasaki & Yamaha) are all inline 4 cyl (except for the RC51 which is a V-twin). And you're right....noone in there right mind would try to turn going 150+mph, although many people still do wheelies

And for those who don't know much about bikes, those 600cc bikes will do 0-60mph in less than 3 secs and 1/4 mile in the 10 sec range with top speed at 150-160mph. Those times, of course, are by professionals. The fastest I ran was a 11.5 on the 1/4mile and I am far from being a professional. And those 1000+cc sportbikes can reach 200mph. And all these times are stock by the way. Notice I said "sportbikes".....the cruisers and those damn Harley hogs can maybe make 12 secs 1/4 mile on a good day hehe.
