Laat je pa dit maar eens lezen:

A single-sided swingarm has been designed to counter torsion forces created by the absence of the "missing" side of the swingarm. It is true that the forces on the shock & springcoil may slightly change due to differences in desgin, however if the angle of the shock & springcoil remains unchanged, these changes will have no negative effect on the durability and stability of the frame and swingarm. This is because a duo-sided swingarm also has torsional flexibility, probably even more than a single-sided swingarm.

The load on the pivot point should remain unchanged, as the wheel remains in the exact same position it was with the duo-sided swingarm. Forces on the pivot point are dictated by wheel position, not by swingarm position.

And keep in mind that this is a 5 BHP moped, not a 100 BHP racing motorcycle. Materials used in mopeds are more than often cheap and flexible and are mostly designed to look strong rather than to be strong. The forces involved in a moped frame and swingarm setup are only a fraction of the forces a (racing) motorcycle has to endure.

Having said this, I understand your worries and objections on this subject. A mono-swingarm isn't the best enginering solution for a motorcycle suspension system and it certainly has it's downsides. However from a purely esthetic point of view, I think you agree with me that a mono-swingarm simply looks amazing compared to a duo-swingarm.
