Attention, prohibited on public roads! This cylinder exceeding the engine displacement of 50cc is only reserved for competition on the circuit, run ....
Here is the high 80cc engine from the Spanish brand BARIKIT for mécaboite driving DERBI euro 1 and 2. This model offers good power and a very large increase in torque. The cylinder is a cast iron model, so it offers great reliability, ideal for endurance, stunt….
The diagrams have an excellent torque / power ratio. The cylinder has a very large booster exhaust and 5 upward revised intake transfers. The base preserves an original shape.With its diameter of 50mm, it offers a real displacement of 78.53cc along with the original 40mm stroke crankshaft of the DERBI engine.
The piston is a two-segment model to once again preserve torque and strength. This piston has received a black graphite treatment, it also has an opening on the back for improved sweeping and side grease nipples! The segments delivered with the kit are made of very fine special steels to allow high speeds while preserving torque.
The cylinder head has a high compression chamber, hemispherical shaped model with a polished finish. The cylinder has a high temperature metal gray paint offering a nice aesthetic. Clearly, it looks a lot like the FURYTECH but it is nevertheless better worked with materials used more upscale. This cylinder will therefore offer you reliability, power (especially with good diagrams, thin segments and an exhaust with boosters) and a lot of torque!
To top it off, BARIKIT has opted for a reinforced aluminum gasket for the cylinder head and the thermal unit has 2 screw locations on each side in order to reinforce it. We only regret that the channels are not worked enough and that the lateral bolts of the cylinder head are not delivered, nor any cylinder head screws. This is just a detail… in view of the price defying all competition. Please note, depending on the arrivals, we may receive the kit in black.
We recommend that you accompany this high engine with at least m: Ø21mm carburetor (24 / 25mm to use it properly), racing exhaust, cold spark plug (B9 / B10 depending on temperature), reinforced crankshaft and bearings.
The pack contains:
-Cylinder cast iron Ø50mm 5 transfers with large exhaust boosters
-High compression aluminum cylinder head with polished finish
-Piston bi segments Ø50mm with side grease nipples, open rear skirt and black graphic treatment
-X2 fine chromed steel segments
-Axis of piston Ø12mm X 40mm in length
-X2 piston clips type G
-Gaskets of pot, cylinder head and base
As an option we offer you 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!
