Reserved only for competition on the circuit, high engine not approved for public roads.
Here is the BRK Competition 88cc thermal unit in diameter 50mm. Like the AIRSAL Xtrem Red, it has a special 45mm stroke. This cylinder / piston and stud bolt offers maximum performance at all levels, it is solid, reliable and efficient! It is designed to be installed exclusively with a 45mm stroke crankshaft, original size 85mm connecting rod such as the special 88cc AIRSAL or BARIKIT 45mm stroke crankshaft. In addition to this, you need to know more about it.
With its 50mm bore diameter and special 45mm stroke, it develops no less than 88.35cc real. In terms of intake transfers, this aluminum cylinder has 5 including 4 lateral and one at the rear with a specific architecture with two internal cylinder lubrication, the front side transfers are designed to pass under the exhaust, the The base is also well designed to offer more performance and improved sweep / fill, you will need to better align the crankcases to the cylinder to develop all the power of this kit. In addition to this, you need to know more about it.
BARIKIT being one of the largest piston manufacturer, this cylinder is equipped with a sapphire blue model single segment piston (blauzafir), so it has a blue graphite treatment. We regret the absence of a preparation on the rear piston to optimize the sweep. This piston still allows high speeds with its fine chrome steel segment (reduced friction).
The Ø32mm exhaust outlet is therefore a very wide model with internal bar, an exhaust wedge for a 28mm diameter passage is provided. This racing version is also equipped with the famous cylinder head which can be broken down into two parts (stud bolt), the latter offers better cooling and therefore obviously additional performance, the stud is an incoming model to preserve a well-centered combustion chamber. The combustion chamber is a high compression frustoconical version, polished finish.
In summary, it is a very good kit, excellent quality / price ratio, the performances are there especially at high speed, it is the maximum power which is aimed without neglecting a crumb of torque.
We recommend accompanying this kit with at least: Ø28mm carburetion, 45mm BARIKIT stroke crankshaft or other with reinforced C4 and / or Celeron bearings, unbridled or competition ignition, racing exhaust suitable for high BRK diagrams, cold racing spark plug, racing 100 engine oil % quality synthesis ....
