To get back to the original question... I would have to say CBR!! In fact, I have a 900RR if you want to buy it!

Now to get back to the argument... Harley is known for being maintenance hogs (no pun intended)! I've had Harley's in my family since I was as tall as a kickstand, and even my family members who own them say that they envy me in the fact that all I have to do it change the oil every 2000 miles and put tires on it twice a year. They are always having to take theirs in for this and for that. Comparing Harley (cruising types) and Jap/Italian Sportbikes is kinda apples and oranges. Harley tried with the Buell, but they just don't have what it takes... not yet. Who knows, maybe someday! Look at the AMA and IMA circuits... no Buell wins, because the majority of them end up with a DNF!
