I was browsing on bikebandit.com for tires. I was looking for stock size tires but going up a bit in size so I was looking for 120/90-17 front and 140/70-18. I could not find any tires that front and rear would be the same. I clicked on there chat and the guy could only find me one tire that had that tire in the sizes i wanted for front and rear.
Avon AM26 Roadrider Motorcycle Tire was what he came up with. These are bias, is this normal for motorcycle tires? In offroading bias tires are not used on the street. If you can just fill me in on bike tires I would appreciate it.
