Answer: A: The g7 are goldwing specified tires for the sizes they require. Dependent on the year of your v star 1300 we should have the excedra max combo for your bike. The are designed for cruiser bikes for long mileage that provides Linear handling and high speed, straight line stability.

Answer: A: You should be able to run tubes in a tubeless type tire without any issues.

Answer: A: The rear tire is offered in a 180/70R-16 which would be a little taller than your stock size 180/60R-16 and the correct size front is offered 130/70ZR-18. The G models are direct OEM replacement tires and would be recommended for your model.

Answer: A: "Radial tires are only available in a tubeless configuration. Bias-ply tires can be had in either tubeless, or tube type. Tube type tires can’t hold air without a tube because the bead is not designed to seal against the wheel efficiently as it does on a tubeless tire. Also, the tire itself is not designed to hold air as some air can escape through the tread. The primary difference between radial and bias-ply is that a radial can sustain a much higher speed rating because the radial tread design generates much less heat than a bias-ply design. Another big difference between radial and bias-ply is in performance. A bias-ply is a very strong tire often (but not always) with a very stiff and strong sidewall. They are very durable and are a real working tire. A radial is a lighter tire by design and is geared around performance with a softer and more responsive sidewall and tread. For example, all sport bikes run a radial tire due to performance and speed rating requirements while many cruisers run bias-ply tubeless tires because their top speed is not very high and the performance requirements of a Harley type cruiser are not very demanding on a tire. Bias-ply are also a bit cheaper to buy than radials due to manufacturing costs." [ sourced from: http://tech.bareasschoppers.com/resources/tires-101/ ]

Answer: A: Yes, these would work great for your 2003 Kawasaki Mean Streak. The sizes for your bike are listed as Radials, you'll want to look for the 130/70R-17 Front Tire and the 170/60ZR-17 Rear Tire..
