A balancing system for use in for example a motorcycle engine to balance forces generated by a piston and connecting rod arrangement connected to a crankshaft. The crankshaft supports a first gear meshing with a second internal gear supported by an intermediate member such that the intermediate member rotates in the same direction as the crankshaft. The intermediate member supports a third external gear driving one or more balance shafts. In a single balance shaft arrangement, the external gear drives the balance shaft directly. In a twin balance shaft arrangement, the external gear drives one of the balance shafts directly and drives the other balance shaft via a further gear supported by a further intermediate member. |
