Sirris R38 Rear Shock for E Ride Pro SR stage1ultrabee Do not consistently ride theThe new Sirris R38 shock brings real big bike suspension technology to compact e motos, using proven internal architecture shared with the larger R46 platform and an oversized chassis built for serious abuse. While other shocks in this class fade, leak, and fail, this one is engineered to keep charging. To accommodate the massive shock for smaller bikes, Sirris teamed up with Prickly to develop an R38 specific linkage (sold separately here).
