Small tube type rear rack

Does anyone make a small tube type rear rack ? I could only find one for the WR250F.
I am looking for something similar to  this http://www.ebay.com/itm/1998-2002-Yamaha-WR426F-WR400F-WR250F-Dual-Sport-rack-426-400-250F-/272280354298?fits=Make%3AYamaha%7CModel%3AWR250F&hash=item3f652c7dfa:g:8-sAAOSw~bFWKDbs&vxp=mtr
for the WR250R . It has to  be small for only carrying a tool bag.

Thanks,
