Social progress is not the same as social change.

This bike may be an example of social change, but it does not strike me as a form of social progress.

Advances in scientific engineering exist regardless of social progress or change.

This bike reminds me of the first mass-production 500cc two stroke. It was trendy, and it sold. Ultimately, it was pulled from the lineup because it did not meet the same mass appeal as it did initially in demand. Too many idiots got hurt, and although the publicity was good for marketing -- it was ultimately bad for business.

Chinese flood the market with poorly engineered bikes. Poor kids can afford them and become smart enough to fix and re-engineer them for continued profit. Social progress has occurred. Social change was too occupied with being trendy and selling the next cool idea.

In other news, how does it respond to forced induction?
