TIRE/RIM WIDTH
Check with the tire dealer first on what size tire that you should be putting on the rear of your bike. IT SEEMS as if Kawasaki has left the rim sizes untouched on the 16" wheels and they are spot on for 100/80 and 120/80, front and rear respectfully. The stock tires (Dunlop 630's) are rather slick/hard and they are okay for basic riding, but the Pirelli MT75 100/90 and 130/90 set up as well as the new Pirelli Sport Demon 100/90 and 130/90, or even consider the Dunlop GT501 110/90 and 130/90...I'd look before I jumped into squeexing to wide a tire on the narrow wheel. Pinching the tire causes wierd handling...Personally I received a letter from METZLER telling me that the ME330/550,
Front 110/90-16 59V TL ME330 BAR/32PSI.
Rear 130/90-16 67V TL ME550 BAR/36PSI, was their recommendation in tire, size and air pressure. I'm waiting to see all the tires at one time...perhaps I should first try to find the hardness (I forgot what this number is called) or density of each of these tires are first. I don't care about the price as much as the grip. The tires are cheaper than dropping the bike even once. I hope this helps...I's sure hate to see you put a wrong tire size on and end up ruining a bike, or worse yet hurting yourself.
