Piece out of production, thank you not to buy this product.

Here is the crankshaft competition BIDALOT G1 / G2 for engine MBK 51. BIDALOT still has some in stock !!! ! This crankshaft is a specific model for the competition, it preserves the original silks of Ø16mm, where you can pose significant bearing origin (Celerons BIDALOT highly recommended).

His race is de plus 41,80mm (origin) to 39,70mm (this crankshaft) for 2 reasons:

1- Do not exceed the capacity of 50cc with senior racing engines has Ø40mm BIDALOT Ø39,93

2- to approach maximum engine square said.

This crankshaft is supplied without a needle cage! Its connecting rod location is Ø16mm. So you can ask them Ø12X16X cages .. mm for axis of piston diameter 12mm and Ø13X16X .. for Ø13mm piston pins. The link remains identical to the original length is between an axis of 85mm. Quality Level one is really on true competition equipment, the masses who otherwise spend in Ø72mm / 43,5mm width (to change in the original housings must be machined has Ø73,5mm), prepared BIDALOT or other ...

Are cut in the highest quality steel, the steel is treated with several preceded to obtain a resistance extraordinary. This crankshaft with its ratings and its unique design provides good inertia as well plains masses. Balancing was neat as it should. The rod head rests on a reinforced cage, a high quality pin Ø17mm CBX. The rod is a broad model forged, the greasings are well studied, it is mounted on anti-friction wedge ...

Each piece is specifically checked and studied BIDALOT before factory. Clearly this crankshaft is a very good model of competition and it is well worth its price. The ignition cones and drives remain as originally leaving you free choice level controller or ignition! This crankshaft location obviously not available to the ignition key.
