Kit 85cc high engine Ø50mm BARIKIT BRK (special 43mm race) DERBI euro 3 & 4

Not approved on public roads, only reserved for competition, does not respect the highway code in any way!

Here is the Ø50mm aluminum cylinder from the great Spanish manufacturer BARIKIT, this version is therefore the most efficient version below the factory prepared series and the BRK series (BARI RACING KIT) in long stroke. This model is designed for the long race 42mm or 43mm DERBI Euro 3 and Euro 4. The cylinder finishing is very clean and good quality treatment nykasil! Level admission BARIKIT remained simple with a 5 all transfers like the team and many other cylinders, the front side transfers are designed to go under the exhaust, the base is also well designed to offer performance and sweeping, you will have to align the crankcases to the cylinder to release all the power of this kit. The exhaust is therefore a very large bar model.

 

 

The diagrams are very high, to make this kit talk, we therefore recommend a good Ø24 to 28mm carburetor and a good racing exhaust. This racing version is therefore equipped with the famous decomposable cylinder head (con culatin / cylinder head), this cylinder head offers better cooling and therefore obviously additional performance, the block is an incoming model to preserve a well-centered combustion chamber.

 

 

The combustion chamber is a high compression truncated version we regret finish this level not high enough, no polishing room, enough low-end aluminum. Apart from this, BARIKIT being one of the largest piston manufacturer , the quality is present, the piston is the sapphire blue model (blauzafir), so it has a blue graphite treatment. We regret the absence of a preparation on the rear piston to optimize the sweep. In conclusion, 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 not the couple.

 

 

We will also regret an aesthetic finish is quite dirty! We will appreciate that the kit comes with 2 base gaskets to make the squish.

 

We recommend this kit with at least : Ø24mm carburetion, 42mm or 43mm stroke crankshaft and reinforced bearings, ignition supporting high speeds, racing exhaust suitable for high diagrams, cold spark plug, 100% quality synthetic oil, removal of the oil pump, etc.

As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
