Data Sheet

Thanks to this Dragrace intake system you can easily mount an RD reed valve without further modifications to the engine block. Due to the decrease of primary compression, this is a sensible step with 125cc and 180cc scooters with the respective cylinders, where primary compression is very high from the beginning. It has turned out, however, that this kit only makes sense with at least a 30mm carb, and only with a 34mm carb can noticeable gains be achieved. Please note that due to the raising of the intake system, the helmet storage will have to be modified as you will otherwise run into problems when mounting the kit and also later when the suspension springs compress. Also fits 50cc Piaggio engines.
