This isn’t an April Fool’s prank. It’s an official deadline that has to be met by all two-wheeler makers in the country. From 1 April all two-wheelers sold in the country have to incorporate either CBS (combined braking system) if they are below 125 cc or ABS (anti-lock braking system) if they are above 125 cc.

This deadline is the reason the last week has seen many dealers offering huge discounts on unsold inventory, to get non-ABS/CBS bikes and scooters out of their showrooms. Regional transport offices (RTOs) can refuse to register vehicles that do not comply with this directive.
