I found NOS shocks that will fit my 73 MX250 on eBay. This seller has a lot of  Redwing Model # KM-S330, 330 mm long = 13" eye to eye.  Includes 8mm and 10mm bushings. He still has over a hundred left over. There is another fella that is selling the same thing but does not have the bushings to go in the grommets.



I have been looking for days and days for something that would fit, and this seems like the ticket. He wants almost $100 a piece with 16+ bucks in shipping. Pricey to me, but I am about at my wits end trying to find something to replace my rusted up old Redwing hammerheads that my bike came with. I thought I would get this out there if any one else has been having the same trouble.
I hope it is OK to post this here.

I have 2 sets of them plus several of the KM-S340. They look good but there are slight differences from the originals. The performance is about the same as original which is best described as "pogo stick". I have '71 and '73 DT and RT Enduros.

I like the longer ones, the bike sits up a little higher. And I ride only on the street.
