People put pipes on Harleys because of the Harley sound. The sound metrics attempt to imitate with big bores and pipes, but can't quite copy the timing setup, which is patented.
O.P. - since you're a newbie rider and obviously trying to do things right, I suggest you spend $30-40 for the Ride Like A Pro video, buy some sport/soccer cones (about .50 each) and go practice the routine in a parking lot until you can do the police level setup in the last half of the video.
You will not only never drop your bike in a slow speed maneuver, but you will then be in the top 2% of all riders out there - and other bikers will look like complete goofs to you with your newfound skills. You will also know what you're doing in the twisties, and enjoy the sport/lifestyle of biking a WHOLE lot more!
Watching the video does nothing though. The neural learning comes from hitting the cone work, learning to automatically apply "head and eyes", "feet up", "friction zone", and the 12 mph steering crossover into countersteering.
Believe me, everyone should take this course, but pride keeps them from doing so, thinking they know how to ride. 30 years of riding is one year of riding done 30 times. Five sessions in the cones is worth your life.
Not to mention you can do things none of your buds can!
