The cylinder is an original &#8220;Big Bore&#8221; cylinder, i.e. it is not based on a standard cylinder that has simply been opened up on, but has been designed as a genuine Big Bore kit with matching transfer ports and a large exhaust that supports the extra power of the cylinder.<\/p>\n<h3>Advantages of Stage6 Big Racing Kits:<\/h3>\n<p>The BigRacing cylinders&#8217; strong points are <strong>simple installation<\/strong>, <strong>top performance <\/strong>and <strong>high reliability<\/strong>.<\/p>\n<p><strong>Simple installation<\/strong>: Installation is extremely easy and, above all, no milling work needs to be carried out on the engine block.
