The first generation Sport Pro MK1 cylinders became very popular among scooter tuners, then Stage6 took things to the next level and introduced the successor, the Sport Pro MKII.\u003c\/p\u003e\n\n\u003cp\u003eThe cylinder was \u003cstrong\u003ecompletely redesigned\u003c\/strong\u003e; 6 instead of 5 transfer ports ensure \u003cstrong\u003eoptimized cylinder filling\u003c\/strong\u003e. The oval exhaust remained but was optimized as well. The appearance is based on the pentagonal shape of the R\/T cylinders. The head is a one-piece unit with cast scavenging canals for better heat dissipation. The piston is a replica of the R\/T piston, with a domed piston crown and 0.8 mm thick piston ring to optimise performance and improve \u003cstrong\u003ethermal stability\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe cylinder delivers 2 to 3 hp more power than the MK1, between \u003cstrong\u003e14-17 hp\u003c\/strong\u003e, without any additional modifications and in combination with the corresponding components. \u003cstrong\u003eMaximum performance\u003c\/strong\u003e and \u003cstrong\u003eoutstanding robustness\u003c\/strong\u003e - we are sure that this cylinder will set new standards in the tuning scene.\u003c\/p\u003e\n\n\u003cp\u003eWe recommend using a reinforced crankshaft, a min. 19mm carburetor and a sport \/ racing exhaust to exploit the full power of this tuning cylinder..\u003c\/p\u003e\n\n\u003cp\u003e\u003cu\u003e\u003cem\u003eThe kit includes.\u003c\/em\u003e\u003c\/u\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003ealuminium cylinder, 47.6mm bore\u003c\/li\u003e\n\t\u003cli\u003e1-ring piston with 12mm piston pin\u003c\/li\u003e\n\t\u003cli\u003eone-piece cylinder head\u003c\/li\u003e\n\t\u003cli\u003egasket set\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWe recommend to clean the engine before assembly, check the condition of all components and use a new spark plug and new small end bearing.
