Whats a good tire for a GSXR?

It really depends on what you want to do, and how you want to ride. IF your agro in riding, you want a high-speed sticky, but that equals higher cost and shorter tire life. If you're granny and want high mileage you'll want a sport/touring tire. Also consider the weather conditions you're riding in. Factor all inputs, including your labor costs for mounting, balancing, etc.

If you take your bike to a shop, expect to pay $350 - $700.

If you learn to remove wheels, and tires, and mount and balance your own expect to pay $200 - $500.

In any case learning this relatively easy but dirty procedure can save you a couple hundred bucks.

Either way, please consider the Dyna Bead balance system over conventional wheel weights. Those tiny ceramic beads do the job. Tires will stay in balance continuously, wear evenly, and last longer.

Bridgestone makes excellent tires for every type of moto application. A lot of riders swear by Metzler, I swear they're overpriced and overrated. Dunlop is very good.

Listen to the marketing or not -that is the question. Also if your not capable of buying it in your locale then there is no point choosing it.
