Cylinder -MALOSSI 77 cc MHR Big Bore (39,3mm stroke)- Piaggio LC 2-stroke
Part no.:
M3113030
Description
With the MHR BIG BORE kits MALOSSI counters in the high-end class with 80 ccm.
It is far from being a simple enlargement of the bore to 50 mm. A closer look reveals the completely redesigned port layout of the cylinder. With small tricks, the flushing behavior was significantly optimized and adapted to the latest state of modern 2-stroke tuning.
The cylinder must be driven with a shaft with 85mm connecting rod length, standard stroke and the 12 piston pin. However, a high quality racing crankshaft with appropriate bearings is recommended in any case, which is also up to the immense power.
Thanks to increased displacement and newly designed port layout, outputs of 26 hp and more are possible.
To be able to mount the cylinder, the engine block in the area of the cylinder base mount must be spindled to 56.7 mm.
