The 3 millimetre longer stroke (standard 57mm, long stroke 60mm) provides 221cc displacement.The most obvious change compared to the otherwise almost identical "old" 221cc MHR kit is the now bolted exhaust flange. Two steel parts (4 times bolted steel plate and socket) now seal the exhaust port by means of an O-ring to the cylinder. The cylinder itself is adapted to the 60mm stroke in that it is 1.5mm longer at the cylinder head sealing surface than its 210cc counterpart.High quality cast aluminiumUltra hard and wear resistant cylinder coating7 overflow ports with large channel cross-sectionsMALOSSI CVF2 systemCoated Vertex piston with a keystone piston ringCentring bushes for centring the cylinder headThis results in relatively tame timing angles by Malossi MHR standards of approximately 182° exhaust to 123° overflow. The exhaust is well prepared with 43,3mm chord width (= 63%) as well as gentle corner radii for a powerful and long piston life.The very large scavenging and exhaust area in combination with not too high head angles predestine the 221cc MHR as an ideal cylinder for all who want to build a fast and powerful power tourer.engine performance of well over 25hp, coupled with a rich torque are possible with the Malossi without further reworking of the cylinder.in combination with our big box exhaust were already achieved 26hp and 29NM, whereby here the full torque is already at under 6000 rpm. Already at 4500rpm there is 16hp at the wheel, literally a "traction engine"...!The kit includes:CylinderCylinder headpistonPiston ringPiston clipsPiston pinGasket setExhaust port, plate, O-ringBushings for head centringTechnical details at a glanceAluminium cylinder68.5mm bore210.06cc'MHR' can be ordered to also suit long-stroke (60mm) crankshafts7 transfer portsVERTEX graphite coated piston with 1 (MHR) or 2 (Sport) wedge-shaped chromed piston ringsCompression ratios : Without MALOSSI HTSR cylinder head – 10.5:1with MALOSSI HTSR cylinder head 12.5:1kit includes base and head cylinder gasketsOEM numbers (for comparison purposes only)Malossi3118599 Compatible with the following models VESPA 200 - P200E 1978-1981VESPA 200 - PX200E 1981-1984VESPA 200 - PX200E DISC 1998 ONVESPA 200 - PX200EFL 1984-1997VESPA 200 COSA VESPA 200 RALLY
