Reserved only for competition on the circuit, high engine not approved for public roads.
Here is the direct competitor of the high engine AIRSAL X-TREM, the thermal unit BRK Competition 88cc in diameter 50mm. Like the AIRSAL it has a special 45mm stroke.
This cylinder / piston and cylinder head offers maximum performance at all levels, it is solid, reliable and efficient! It is designed to be weighted exclusively with a 45mm stroke crankshaft, original size 90mm connecting rod like the special 88cc AIRSAL crankshaft or BARIKIT stroke 45mm.
Thanks to its Ø50mm bore diameter and 45mm stroke, it offers no less than 88.35cc real. As for the intake transfers, this aluminum cylinder has 5 of which 4 are lateral and 1 at the rear with a specific architecture and internal cylinder lubrication.
The front side transfers are designed to go under the exhaust, the base is also well worked to offer more performance and improved sweeping / filling, you will have to align the crankcases to the cylinder to get all the power of this kit.
The exhaust outlet is therefore a very wide bar model. The diagrams are high and sharp. 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.
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.
Clearly, 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 the couple.
We recommend accompanying this kit with at least:
- Carburation Ø28mm
- 45mm BARIKIT stroke crankshaft or other with reinforced bearings
- Unbridled ignition or competition
- Racing exhaust adapted to high diagrams
- Racing spark plug
- 100% synthetic engine oil of quality
- Removing oil pump ...
This pack contains:
-Aluminum cylinder Ø50mm 5 transfers with large bar exhaust
- Two-part decomposable aluminum cylinder head
-Piston mono segment Ø50mm sapphire blue
-Segment fine chromed steel
-Piston pin
-C type piston clips
-Pack of engine seal
-Notice
- Screws, washer ...
As an option we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
