ask : Fz150i Tires info..

is it good if i change my rear tire with 120/70 or 120/80 with the standard rim 17" ?

and what brand should i used better for touring (if have the shop name can tell me also, i live in KL) ?

and do i need to change my gear (not the gearbox, but the gear near the rear tire) if i change into the bigger tire ?

thanks.. i really appreciate ur answers..

no it not are good idea to fit that size of tyre to fz standard rim i have try it and the tyre tread eventually will go donut you have to see oem rim(more width rim bead like 3 " more) like tajforums can help orders for your.
