MALOSSI C-One crankcase for scooter with a Minarelli 2-stroke LC engine.
The cylinder base of this crankcase is tilted 10° degrees compared to the original shaft-gear axis. This innovative measure makes it possible to position the engine ports in front of the fuel system, eliminating one of the major weak points on the original Yamaha / Minarelli crankcase. However, it may be necessary to modify the helmet compartment.
The base of this C-One Yamaha / Minarelli crankcase has two different stud arrangements for mounting the cylinder with grub screws or for cylinders with flanged mount by means of flange and short threaded screw of max. 47.6 diameter.
The C-One crankcases are intended exclusively for scooters with standard rear disc brake! The axle spacing has been extended and with it the stability and steering precision, while the gearbox space has been significantly reduced.
