Made of the same high-strength aluminium alloy as our racing cylinders and nickel-chrome coating. The central core profile has been revamped around the ports to increase the heat exchange surface and improve the air cooling flow, allowing the fresh air to enter the combustion chamber at optimal temperature and pressure conditions, thus improving the volumetric efficiency of the engine. There is a support surface in the front part of the cylinder that has been machined and finished with high-precision tools, with four threaded holes required to connect it to the pipe assembly. The most…
