Big Bore cylinder kit from MVT, suitable for crankshaft with 44.8/45mm stroke, made of gray cast iron, suitable for everyday use and durable with a brutal 90cc displacement and very good torque curve. No orgy of revs, just pure power and torque. This is made possible by an MVT 7-channel design with additional boost ports in the exhaust and a special cylinder head with a high-compression combustion chamber contour. A larger carburetor is definitely advisable: We recommend from D=21mm. If you want to be on the safe side here and are looking for additional performance in addition to durability, you can optionally install a 44.8 mm MVT VI Racing crankshaft.
We strongly recommend an exhaust system suitable for 90cc in such a way that the power can be optimally and fully utilized, otherwise you will choke off the power of this beast.
