Only the later 2021-up models have an automatic clutch cable adjuster installed; which is made of plastic. The Müller ''Clutch Control'' adjuster will replace this poor quality OEM part and allow you to adjust the clutch quick; easy and with perfect precision; without all associated issues of the OEM part for the best possible clutch feel and function. This ''Clutch Control'' is especially beneficial for clutch adjustments of 21-up models equipped with OEM plastic adjuster but will physically fit all 18-up models with cable clutch.Note: Compatible with clutch cable models only. Attention: This Power Clutch does not fit Revolution Max models or Trike models from model year 2026 onwards. Note: Compatible with clutch cable models with stock clutch lever or; depending on model; with 723223 (Gen1 Softail); 723224 (Gen1 Touring); 723225 (Gen2 Softail) or 723226 (Gen2 Touring) Müller Motorcycle adjustable lever kits only.
