The most biased and uneducated article I've read on this site in a long time.
The article is intended to drive a wedge even further by annoying legit motorcycle riders (sportbikes with stock cans mostly) and please the croud that has no experience with motorcycles or racing who are simply annoyed by the noise and don't care to differenciate it. Hey, let's just say - all motorcycles are noise makers so let's push them off the road next time!!!! Very well done indeed!!
Thankyou author... NOT!
While I totally agree that the noise is very annoying, Harley's racket is far louder and exceedingly more annoying than any sports bike, yet the author singles out sports bikes.
And having read this article, all F1 stables are now privy to the newbreakthrough! They should install a quiet muffler to make their race cars faster!!!
