Transmission · Sprocket offset
Ref. OP202
Opus gearbox output sprocket offset kit for Mini 4-strokes with Daytona Anima or Zongshen 190/212 cc electric-start engines, required once the wheel exceeds 4.0 in width. It offsets the sprocket by 18 or 26 mm.
Fitting requires modifying the ignition cover (material removal, see product photos) and is intended for an experienced, well-equipped mechanic. When tightening the plate, make sure to keep at least 0.5 mm of lateral play on the sprocket, adding washers to the spacers if needed depending on the engine.
