The only CIAO/SI cylinders on the market with a split exhaust port and symmetrical transfer ports!!!! Threaded type exhaust header offers two major advantages: Increased strength and the possibility for replacement due to failure. Possibility to increase the exhaust size hence increasing the performance. These results are possible due to a smaller decompression valve, compared to the Piaggio original, which is supplied with the kit. Centred,…
