I use 90/90 X 19 f,and 100/90 X18 R
in Avon Roadrider,they are fantastic,great grip dry and wet,
run 29 psi F ,and 36 psi rear,
make my 500 feel like a 250 !!!
got about 9,000 miles for the front,and 3,000 for the rear,
for that reason,I am fitting Dunlop Streetsmart ,3.25 X 19 F ,and 4.00 X 18 rear.
main difference is the greater diameter overall,the Avon caused the speedo to read about 15% slow
will let you know how the Dunlops feel
