The 2EXTREME sports cylinder is a 70cc cast iron cylinder at a low price. The cylinder kit offers an excellent combination of performance and holding capacity and is one of the best among the top cylinders. The large flow rate and wide exhaust ports provide powerful torque and amazing top speed, even with the original exhaust system and carburetor. This sports cylinder is ideal for everyday use, with an ideal engine setting you can achieve power values from 8 to 10 hp effortlessly.
The kit comes with all the small parts needed such as gasket set, piston rings, piston clips, etc. The supplied cylinder head also requires a long wire spark plug with M14 thread.
The kit can be used with the original carburetor if the main nozzle is enlarged by about 7-10%. However, we recommend the use of a 17.5mm carburetor to increase internal cooling and therefore durability as well as performance.
