Should be an easy fit on any small-frame Chinese minibike (Baja Doodle Bug, etc.) with a 12 mm axle. I imagine they could be fitted to vintage USA minibikes after reaming the axle and steering head bolt holes to fit; appears to be sufficient material to allow reaming the axle holes to accept a 5/8" axle. They may have a Mega Moto or Monster Moto logo cast in the sliders (lowers), though; some may dislike that. The coveted Motovox suspension forks are nearly impossible to find, now; these appear to be very similar. Zero offset; I'd probably change that by modding the triple clamps. Price seems reasonable. I'm going to order one to see what they're like; if they're decent, I may order a couple more to stash.
