Got some new Metzeler Lasertec's for my GS1000. These are bias-ply and use a tube. With the stock wheels, I can't fit a radial or tube-less tires. The front is a 100/90 V19 and the rear is a 130/90 V17. Just 10mm wider than most front tires on modern bikes. And the 90 percent height gives the tire a very rounded profile.
The bike came stock with IRC tires, but I have used Continental, Michelin, Pirelli, and Metzeler. I've been using the Laser model from Metzeler for about 20 years now. Many of you have probably never seen a block-pattern like that used on the front tire, but it works very well. On the rear, I've used the ME99 and ME55 models. I believe the Lasertec is the same as the ME55. The Metzeler ads say they use a new formula for these tires.
The old Suzuki handles very neutral with the Metzeler's. I like that. I don't go crazy into corners, but I like to power out of them. The GS only makes around 80hp, but has a ton of torque down low. The Metzelers work very well with the gas on and leaned over. Only got 6K out of them and like on my CBR, the front wore out before the rear. Actually, I should have replaced them at 5K. I ride mostly streets and backroads, and rarely take the highway, but I recommend the Lasertecs for older bikes that use bias-ply tires.
