Here is a very good small 70cc cast iron kit for SUZUKI SMX and RMX 50cc, it is the BARIKIT Ø47mm model. This cast iron model therefore offers real 70cc of torque and power, ideal for endurance riding or every day where the legislation allows it because very torquey, it does not neglect power and it is very solid!
Its cast iron cylinder therefore has 6 intake transfers + 2 bottom filling (admission port has bar) for filling the bottom engine and the sides. Its admission is reworked, we also advise to mount a 19mm PHBG carburetor on the cylinder see 21mm or 22mm if you rework the admission slightly, the Ø for the sleeve is 27mm.
This cylinder has a very large exhaust port, with diagrams all the same high enough for a cast iron, which offers very good power, especially coupled with the good compression ratio offered by the hemispherical combustion chamber with polished finish. This kit does not neglect the torque with its two-segment piston and its compression ratio. The finish is not excellent either (more, it must be admitted!
But for a reduced price, you will have a powerful, torquey and very solid engine! A very good base of preparation also for the more connoisseurs. The cooling system is also improved thanks to the cylinder head well worked at this level. This kit preserves an outlet for depressions and separate lubrication.
Obviously to support and use the kit well, you will need a reinforced crankshaft, a good expansion muffler, thicker slat valves in carbon or fiberglass ...
The pack contains :
-Cylinder head
-Cylinder
-Piston
-Segment
-Axis
-Piston clips
-Pack full seal
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
