I bought my R1 with what I'm assuming were factory tires. The bike was scary even tho I'm an experienced rider. I almost wrecked it several times just because the factory tires wouldn't hook up! I ran the Conti Road Attack on my previous R6, and absolutely loved the tire. After doing some research and knowing my experience with the Conti tires, I thought the Attack 2's would be a good "fit" for my R1... I was right!!! Bike finally corners like it's on rails and power wheelies on command! Absolutely phenomenal tire for "normal" street riding!
