ZR motorcycle tires

[Jessechop]

I need a 21" (90/90 ideally) front ZR rated tire and a 19" (100/90 ideally) rear ZR rated tire. I have looked all over and cant locate any. Does anyone know of any manufacturer that makes ZR tires in these sizes?

I am running 21s on front and rear but don't need the +130 speed on my Triumph Cub.............I'll be interested if you find them.

Good luck, I don't think there is such a thing.  Why does it have to be a 21"?

Very narrow profile for less air and salt resisitence................I don't know if it matters on big horsepower...........but it seems to help on my little Cub.  I also was able to mount a very narrow fender from the rear of a 26" bicycle that matches the tire width.
