70cc high engine Ø47mm BARIKIT cast iron DERBI euro 1 & 2

Not approved on the public highway, only reserved for the competition on closed circuit or road!

This cylinder kit with piston head BARIKIT cast is a little common model and rarely marketed. This cylinder has 5 admission transfers including 4 plus 1 back side and an exhaust boosters with an output enlarged oval. With its 47mm bore diameter, it offers real 67,66cc normal race (like the original).

 

To ensure good strength, BARIKIT used quality cast materials and was accompanied by a dual piston segment to slow high revs to maintain the torque and good strength, the internal architecture is studied and finishing average, however, for such a price it still offers excellent performance even though we are far from the quality of a kit MALOSSI MHR, POLINI ....



The piston is thus a two-segment aluminum with a high silicon content, thanks to that it will be a major asset in the couple, the strength of the engine and slowing high speeds by increased friction, the two segments are fine ( 1 mm thick), they are chromium steels and allow through their subtleties combine high torque and engine systems.



The cylinder head is a high compression aluminum model with a hemispherical combustion chamber, polished finish. The latter is mounted on O-ring and guarantee a perfect engine sealing.



In summary, this high engine is a model to the torquey diagrams, relatively good and very solid. Nothing prevents you to mount it with a crankshaft long race 43mm with a wedge base of 1.5 mm, which offer you a kit 75cc cast-powerful, strong and out of the common. The only negative, no cylinder head bolts is provided either manual or sticker ... but that's a detail.



We recommend installing this kit with at least: carburation 19 or 21 mm with flexible mounting, complete intake kit, exhaust racing, reinforced crankshaft, reinforced bearings, cold candle racing Iridium racing motor oil 100% synthetic ....
