Stage6 R/T Rear Shock Absorber Replica – little brother of Stage6’s HQ gas-charged R/T shock absorbers. Please verify the length you need! these work on ALL MORINI SR50, aprilia sr50, and minarelli. Again please verify your shock length before ordering. Spring pre-load and rebound damping can be adjusted with wheel nuts at both ends. As a “replica” shock, this is mainly developed for sportive road riding with premium quality suspension. As you can see, a lot of attention was spent on design and finish, with anodized orange applications for an authentic racing look. Details: Spring rate: 160LB Length: 310mm
