We verify connector compatibility ourselves (as of 2026-07-30). That means the mechanical and electrical plug interface — not further properties of the drive or the headlight. Before installation, check the requirements of the drive system and the lighting. If you are unsure, contact us or have the work done by a specialist workshop.

Common mistakes

  • Confusing Universal articles with system-plug cables: these products extend or join — they do not replace a BES3 / Yamaha / Micro M system plug.
  • Expecting CT22 in the Y workshop pack: YCc50b-Nuw (EAN …176) contains Y cables only; 3× CT22 only in single pack YCc50b-Nus (EAN …060). Order separately for the workshop: art. no. CT22-BO100 (100-piece box).
  • Expecting CT22 with the CT1 extension CAc30: CAc30 has no open ends and no CT22 (EAN …053 / …169).
  • Mixing workshop and single-pack EANs of the extensions: same tech, different quantity.
