M14x1.5mm to M12x1.5mm threaded adapter / adaptor for the thermocouple - Piaggio 640485 - to mount a spare or tuning cylinder on the Derbi D50B0 E4 engine (2018-).
The thermocouple on the Euro4 version of the D50B0 engine, used in all Derbi Senda, Aprilia RX/SX and Gilera RCR/SMT from model year 2018 onwards, has been given a different tap hole.
As a result, all aftermarket and tuning cylinders from model year 2018 onwards cannot be used because the temperature sensor is coupled to the ECU and must be installed.
