Fasstek crankshaft Big Block 111 YZF R 125 V1-V2 - MT 125 V1
The Fasstek ProStreet crankshaft is CNC machined from solid 4340 aerospace grade steel. The quenching and heat treatment have a superior resistance to wear, because it has undergone Plasma ION Nitriding!
The ProStreet is fully balanced and ready to install to the highest quality and tolerances for a perfect fit in your lower engine.
The kit is delivered with the masses, forged connecting rod, bearing and assembled distribution pinion in order to reduce the technicality of assembly.
The crankshaft with its 74.70mm stroke, will perfectly suit the "Fasstek long stroke" Big Block cylinders ranging from 190cc and 290cc.
You will lose a little maximum speed but in return, the torque will be increased on your engine!
The crank pin is 28mm which is very suitable for track or Run ;o)
Mechanical tip: For the reassembly of your engine, we strongly recommend that you purchase a new timing chain and an adjustable timing sprocket in order to be able to set your timing to your convenience or the technical specification of your Racing camshaft!
