.This is a n.o.s. rear fender for your Arctic cat minibike, Prowler, Screamer, Whisker, etc. Will also work on Attex, Colemans, and Simplex minibikes. Measures 17 5/8" long by 4 5/8" wide, mounting holes are 3 1/2" apart. When you are sitting on your minibike, the notched edge is on the left side, (notched for chain.) This one works with the Saxonette motor. Nice chrome!
