India is one of the largest markets for motorcycles in the world, where the exhaust emissions have a particularly significant impact on city air quality and public health. To address the growing air pollution challenge, the Indian government has gradually established and implemented the Bharat Stage (BS) vehicle emission standards, systematically regulating motorcycle exhaust emissions.
The BS framework is largely aligned with European regulations and made a significant leap in 2020 by skipping directly from BS IV to BS VI, which upgrade sharply tightened limits on exhaust emissions, while introducing, for the first time on two-wheelers, requirements for OBD diagnostics, durability, and emission consistency.
With the advent of BS VI, India has further strengthened real-world emission controls through measures such as BS VI Stage II, which focuses on RDE (Real Driving Emissions). Currently, stricter BS VII emission standards, along with complementary fuel economy regulations, are in planning and preparation and are expected to be gradually implemented around 2026–2027. These developments will place higher demands on the sensing capabilities and closed-loop control precision of motorcycle emission systems, making reliable exhaust sensors increasingly critical.
As a leading manufacturer of gas sensors and gas analyzers, Cubic has accumulated over 20 years of R&D experience on gas sensing technologies and has a specialized Zirconia oxygen gas sensor portfolio for motorcycle exhaust gas emission measurement, which could support OEMs to meet regulatory compliance requirements in the Indian market.
Cubic motorcycle oxygen sensor is designed on the basis of HTCC technology. The sensor delivers stable output, high signal resolution, and a fast response time of less than 15 seconds. Its standard voltage signal enables easy integration with motorcycle ECUs, supporting closed-loop air-fuel ratio control and allowing the engine management system to respond quickly to changes in exhaust oxygen concentration.
Built for demanding exhaust environments, the sensor features a Thermal Shock Protection (TSP) coating that enhances resistance to thermal shock, engine vibration, dust, moisture, and condensation. With a maximum operating temperature of up to 850°C, it provides reliable performance under high-temperature operating conditions.
The miniaturized planar structure offers greater installation flexibility, making the sensor suitable for space-constrained exhaust systems. Its broad compatibility with EFI motorcycle models makes it applicable to motorcycle OEM manufacturing, aftermarket modification, maintenance and repair, and emissions compliance testing.
Combining compact size, fast activation, reliable high-temperature performance, and accurate oxygen measurement, Cubic motorcycle oxygen sensor offers a practical and durable solution for motorcycle engine management, air-fuel ratio optimization, and emissions control.
As an automotive Tier 1 supplier certified to IATF 16949, Cubic combines automotive-grade quality management, automated mass production capability, and proven reliability to deliver motorcycle manufacturers a robust exhaust emission measurement solution, supporting regulatory compliance and enabling the development of safer, cleaner motorcycles for the future.
