MVT Iron pro Max 90cc cylinder:

The 90cc cast iron cylinder was developed for sporty everyday use and offers a perfect combination of performance and durability, with good acceleration and very good torque even at low revs. It has 7 transfer ports and a large exhaust and a 2-ring piston with 13mm piston pin. It comes with a high-compression aluminum cylinder head, which provides a great racing look thanks to its orange paint finish.

MVT SC crankshaft:

The MVT SC crankshaft is very robust and developed for high engine speeds. The full cheek shaft improves pre-compression. The balancing is extremely precise to reduce harmful vibrations in powerful engines. This crankshaft is equipped with a heavy-duty CNC connecting rod with 44.8mm stroke and 90 mm forged, polished steel connecting rod. The crankpin has a diameter of 18mm and the piston pin bearing is silver plated and designed for a 13mm piston pin, giving it greater strength compared to a 12mm crankshaft.

PROFi TIP: To get the best out of this kit, a 28 to 32mm carburetor and MVT SC exhaust is recommended.
