Crankshaft, connecting rod assembly BARIKIT COMPETITION long race 43mm for motorcycle 50cc DERBI GPR euro 1 & 2 with balancer

Attention, this crankshaft increases the engine displacement, it is in no case homologated nor allowed on road.

The crankshaft BARIKIT race 43mm is already very famous in this new version. This crankshaft in this long race 43mm will allow you to gain in cubic capacity. This crankshaft allows you for example to pass a kit MALOSSI MHR team of 76.57 to 84.43cc real all approaching the engine of the motor movement called "square", a performance gain really present. However, attention, the passage in long race increases the diagrams, so do not ask a kit that has very large diagrams in 40mm stroke on a race 43mm otherwise you will get unusable diagrams. We do not recommend the passage of a kit 50cc (d.40mm) in long race, you would turn in hyper race ... In short, the race 43mm if it is well accompanied will prove to be a very big gain of torque and performance. If you want to put this crankshaft on a kit designed for the BRK as race 43mm you have nothing to predict, however if you want to put on a kit for normal race like MALOSSI MHR TEAM, TOP PERFORMANCE or other ... You need provide a shim 1.5mm thick ! You also need to plan to align the lights in the bottom dead center, we advise the verification of the diagrams during the assembly. From now on, BARIKIT long-stroke crankshafts come out in Ø20mm bristles like some BIDALOT or some ATHENA racing.

You will have to ask big model bearings (those of minarelli scooter / booster or DERBI), a specific bearing pack with seal spy exists in this size, in ATHENA but also in 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 connecting rod and the steel used is fairly low ranges . The small-end cage is also revised upwards for added strength, a reinforced 12X16X16mm model has been installed and each crankshaft lubrication has been studied.
