Crankshaft, connecting rod assembly long BARIKIT COMPETITION race 43mm for mécaboite driving DERBI euro 1 & 2 except GPR

Attention, this crankshaft increases the engine displacement, it is in any case approved or authorized road.

The crankshaft BARIKIT race 43mm is already very famous in this new version. This crankshaft in this long race 43mm'll save you in displacement. This crankshaft enables you for example to pass a kit MALOSSI MHR team of real at 76.57 84,43cc all approaching motor motor movement called "square" a gain of really this performance. However beware, the long passage race increases the charts, so do not pose a kit which has very large diagrams in race 40mm on a 43mm stroke failing to obtain unusable diagrams. We do not recommend completely the passage of a 50cc kit (d.40mm) in long race, you would turn in hyper race .... In short, the race 43mm if it is accompanied avéreras will be a very big gain in torque and performance. If you want to ask this crankshaft on a planned kit as BRK for race 43mm you have nothing to predict, however if you want to put it on a normal kit for race like MALOSSI MHR TEAM, TOP PERFORMANCES or other ... You need provide a 1.5mm shim ! You also need to provide better align the lights at bottom dead center, we recommend checking the charts during assembly. Now, crankshafts BARIKIT long runs out in silks of Ø20mm like certain BIDALOT or some ATHENA racing. You will have to ask large bearings model (those of minarelli scooter / booster or Derbi), a specific roll pack with oil seal exists in this size, but also in ATHENA BARIKIT. Apart from that, this crankshaft remains quite correct in relation to its price, the masses are full for more pre compression, equalization is done digitally ... The finish is good, however the rod and steels used is fairly low ranges . The connecting rod cage is also reviewed on the rise for strength, a model reinforced 12X16X16mm was made ​​and each lubrication of the crankshaft was studied.
