Description

BIG DEPS 4 MHR Ø 47 Cylinder kit


The cylinder draws its peculiar characteristics from the BIG DEPS range: the same aluminium alloy, barrel with nickel-chromium coating, the same redesigned central core and identical ring washing strategy.
The support surface in the front part of the cylinder continues to be worked with high precision diamond tools and has 4 holes for fixing of the exhaust flange.
The result has translated into a further and significant increase in performance!
Finally, the most reliable and safe strategy of coupling and centring between cylinder and head has also been applied to these cylinders: external centring!
Using this technique, the same used in our range of racing cylinders, the relative centring of the two components is obtained thanks to a high precision coupling created on a diameter external to the cylinder fixing studs.
This strategy is successful because it does not require any interface component, such as, for example, bushings, and moreover, being created on a diameter external to the studs, it can be used to exploit areas of the cylinder normally free from further tensions, typical of the geometry close to the barrel, where combustion takes place, without dangerously overloading the resistant structure.
The position makes the machining more agile and allows greater precision of the couplings.
