Attention, prohibited on open road! This cylinder exceeding the engine displacement of 50cc is only reserved for competition on the circuit, run ...! To accompany its Ø48 mm cylinder head with stud, available in accessory link.
Here is the BARIKIT Racing cast iron cylinder / piston without cylinder head which is a very rare model and rarely sold. This model has 4 side transfers plus a rear, in addition, it has a boosters exhaust. It is the most special cast iron on the market. With its Ø47mm bore it offers real 67.66cc To preserve good strength, BARIKIT used a very high-end cast iron and fitted a two-segment piston to slow down the high speed. The admission is therefore made by 5 transfers, the exhaust is very wide and has 2 boosters.
The piston is therefore a model with 2 segments in order to slightly slow the high speed for the benefit of torque and strength, these segments are very thin (1mm), they are also chrome, treated, lapped.
In the end, this cylinder is a model with very torquey diagrams, it is relatively powerful and very solid. Nothing prevents you from mounting it with a 43mm stroke, which would give you a 75cc cast iron kit overpowered and out of the ordinary. We recommend mounting this kit with: 19 or 21 mm carburetion, racing exhaust, reinforced crankshaft, reinforced clutch and reinforced bearings.
The pack contains:
Ø47mm cast iron cylinder with 5 intake transfers and boosters exhaust.
Bi segment piston Ø47mm.
Piston pin Ø12 X 40mm.
Complete attached pack.
X2 hard chrome domed segments 1mm thick.
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!
