20" front wheel for a DR-Z400SM ?

[strandedinnz]

Anyone know where I can get a 20 or 21" front wheel that would fit to a DR-Z400SM ? I want to play more in the gravel but I've found the 120/70R17 to be a bit fat and skittery to be fun and want a skinnier front wheel I can just swap on.

Thanks!

Torpedo7 sells wheel sets for them. 21" front and 18" rear. And they come in all different colours which is pretty neat. Link (http://www.torpedo7.co.nz/products/T7WHSN0MX/title/torpedo7-mx---enduro-cnc-wheel-set).
