If this is what I think it is then I have a couple lol. They have no decals so I thought they were generic Landar or something as they were quite gimmicky. Unless someone was sniding them in 84/85 then they must be SST. At 14 and 6'2" racing I went through seatposts at a rate bending both steel & Renthal laybacks alike. My local shop SPEEDYS (ran by Jen & her son Paul Speed (Dales age group at the time) was an SST stockist and judging by the amount of Dirt skirts & stickers i still have rattling around my gaff, it makes sense thats what they are, just couldnt remember. Funny.
