I love the Metzeler 880 Marathon for rear and Lazertec for front. Stock size. I did not feel tires were slick with first few hundred miles. One thing I did notice bike seemed to vibrate more while riding, others on this site noted what seemed like vibration was actually the tire gripping the road. The first few times I had the confidence in Metz and took a corner real hard, I was amazed how good the tires held the road. The Bridgestone tires would slide around, In the rain the difference is incredible.
