Cubic Inch Stroker Kit for M-8
S & S Cycle has been building big bore kits since the 1960s and has " Proven Performance " down to an absolute science . Its latest efforts are aimed at the Milwaukee-Eight platform ( 2017 and newer big twins ) and " opens up a whole new level of performance for these engines " - combining a new design forged piston with its 4.25 " cylinders to net a tire-melting 131 cubic inches when paired with its 4.625 " stroker crank . " We build our big bore kits and cranks to much tighter tolerances and with higher quality materials than the factory parts ," states Product Manager Grant Hillegass . " It ' s hard to argue that and we believe this new piston / cylinder kit will be a solid platform for massive power - we can ' t wait to see the beasts that will get built around it !"
