Attention, not homologated on road, reserved only to the competition.

Here is a small kit of the Spanish house AIRSAL, this kit aims at the low price but also and especially the quality! Attention, some competitors calls this kit the T6 but the T6 70cc d.47mm has not been released for more than 10 years at AIRSAL. This kit is therefore the T4, it is besides the only 70cc of AIRSAL for engine MBK 51 air. The cylinder of this kit is an aluminum model treated nykasil high-end, its diameter of 47mm offers exactly 72,52cc real in combination of the original race 41,80mm of the crankshaft MBK 51.

It has 2 side transfers and 2 rear transfers, the architecture is very good and it is very based couple. The intake diagrams are very high which will facilitate the task of a preparer who will have as work only to increase the exhaust diagram which is it really small. The exhaust width is also very small and can be increased by an ample 35%.

The piston is of very good quality, it is a model bi-segment thickness 1.50mm, we will regret nevertheless normal sections not chrome curved but has such a price ... In short, this kit is a model very robust, very Well studied, it aims more the couple than the power but a good preparer can transform it into a monster of power. It certainly does not expect a quality / architecture like MALOSSI, ATHENA or MALOSSI, but it is really the best value for money / performance of the market.

We recommend to accompany this kit with at least : carburation 15mm, crankshaft and reinforced bearings, exhaust of relaxation, candle to the appropriate grade, cylinder head d.46 or d.47mm.

The pack contains :

X2 normal segments d.47 X 1.5mm
X1 piston bi segment d.47mm
X2 piston clips type G
X1 piston pin d.13mm
X1 cylinder head gasket
X1 cylinder aluminum T4 d.47mm normal exhaust

As an option, we offer a STAGE 1 preparation. This preparation includes a selection of the best part of our stock, a clear improvement of the shape and the exhaust diagram as well as a special retouching of the skirt and the piston according to our Best trials. This prepayment requires an additional delay of 2 to 10 days according to our availability! It requires tools and around 1h30 of working on this cylinder. The price is therefore accordingly.
