my 750 has cheapo tires on them and they dont display tire size on the sidewall like i was hoping. a guy i used to work with set me up with a pair of brand new kenda challengers for $75. the sizes are 110/90-19 and 100/90-18. i havent tried to peel them on my rims as i'm waiting for a new rear wheel from e-bay. before i set my self to the task, does anyone out there know if i've got the right size skins? i have plain old stock rims on my scoot.
