Introduction:
With the enforcement of EURO4 regulations, a pivotal shift occurred in motorcycle safety standards. As of January 1, 2017, it became mandatory for all new motorcycles with over 125 cc to feature ABS (Anti-lock Braking System) as a standard, while those with 125 cc were required to have at least CBS (Combined Braking System). This marked a significant leap in ensuring enhanced safety measures for riders.
Understanding ABS and CBS:
- ABS (Anti-lock Braking System):ABS is an electronic system designed to prevent wheel lock during abrupt braking. Particularly crucial in wet or slippery conditions, ABS utilizes wheel speed sensors to detect rapid deceleration. Without the rider reducing brake lever pressure, these sensors send signals to the ECU (Electronic Control Unit). In response, the ECU adjusts brake caliper pressure, preventing wheel lock. Once the risk of lock is eliminated, the caliper pressure is restored.
- CBS (Combined Braking System):CBS, on the other hand, operates by distributing braking force between both wheels. It effectively prevents excessive rear wheel lock by connecting the front and rear brakes. This contributes significantly to minimizing stopping distances.
How Both Systems Work:
- ABS Operation:ABS relies on wheel speed sensors placed on the wheels to detect abrupt deceleration. Without requiring the rider to reduce brake lever force, these sensors transmit signals to the ECU. The ECU then adjusts the pressure of the corresponding brake caliper, preventing wheel lock. The caliper pressure is reinstated once the risk of lock is no longer detected.
- CBS Functionality:CBS interconnects the front and rear brakes. When the rider applies the rear brake, both wheels are proportionally braked, optimizing the maneuver as much as possible.
Pros and Cons of ABS and CBS in Motorcycles:
Understanding the distinctions between ABS and CBS, it’s crucial to evaluate their respective advantages and drawbacks.
Advantages:
- Enhanced Safety in Emergency Braking: ABS ensures that wheels do not lock during sudden braking, providing critical safety, especially in emergency situations involving distracted pedestrians, road obstacles, or unpredictable hazards.
- Optimized Braking Manoeuvers: CBS, by linking front and rear brakes, aids in evenly distributing braking force, contributing to optimal stopping distances.
Drawbacks:
- System Complexity: Both ABS and CBS systems, while enhancing safety, introduce increased complexity to motorcycle systems, potentially leading to higher maintenance costs.
Evolving Innovations in Motorcycle Safety Systems:
Recognizing the importance of continuous improvement in safety features, leading motorcycle manufacturers have been at the forefront of developing advanced systems.
- Honda’s C-ABS: An electronic iteration of ABS, contributing to heightened braking efficiency.
- Kawasaki’s KIBS Technology: Kawasaki’s innovative braking system that advances braking control.
- Suzuki’s Motion Track ABS: A technology designed to elevate ABS performance in various riding scenarios.
- BMW Motorrad Race ABS: Tailored for their high-performance “supersport” motorcycles, this ABS system showcases BMW’s commitment to cutting-edge safety.
Conclusion:
The implementation of ABS and CBS in motorcycles reflects a commitment to rider safety. While each system has its unique features and benefits, the overarching goal is to provide riders with advanced braking capabilities in diverse scenarios. As technology evolves, manufacturers continue to push boundaries, introducing innovations that further enhance motorcycle safety standards. Understanding the nuances of ABS and CBS equips riders with the knowledge to make informed decisions, ensuring a safer and more enjoyable riding experience.
