Yokohama Rubber Company announced today that, together with the Surat Thani branch of the Rubber Authority of Thailand (RAOT), it held a seminar event in December in order to help Thai natural rubber farmers improve the quality and productivity of their natural rubber. Fifty farm households in the Surat Thani area participated in the event. Yokohama claims that each participating household received a complimentary 250 kg of fertiliser developed using RAOT’s specialist knowledge. The seminar is the fourth held by Yokohama Rubber and RAOT since 2020.

Yokohama states that it signed a Memorandum of Understanding (MoU) with the RAOT in January 2020 in order to cooperate in efforts to provide economic support for Thai natural rubber farmers and to improve traceability to ensure transparency and soundness of the natural rubber supply chain. The MoU and events held under it are concrete actions based on Yokohama’s ‘Procurement Policy for Sustainable Natural Rubber’. According to Yokohama, the farmers who received fertiliser at this event are cooperating in follow-up surveys on its effect on the physical properties and productivity of their natural rubber. Another action under the MoU is a program of onsite surveys that began in 2019 that seeks to analyse the issues faced by natural rubber farmers in Surat Thani area, home to Yokohama Rubber’s Thai natural rubber processing company, YT Rubber Co., Ltd.

A founding member of the Global Platform for Sustainable Natural Rubber (GPSNR), Yokohama claims that it revised its ‘Procurement Policy for Sustainable Natural Rubber’ in September 2021 and is strengthening its collaboration with GPSNR activities. The recent seminar event in Thailand reflects the principle of ‘Support for suppliers, including small-scale farmers and other parties involved in the supply chain’ set forth in the procurement policy. As per Yokohama, the tyre company will continue to implement and announce initiatives in line with the action guidelines stipulated in this policy. The company is also endeavoring to achieve the Sustainable Development Goals (SDGs) adopted by the United Nations. Yokohama states that as part of these efforts, the Yokohama Rubber Group is promoting the procurement of sustainable raw materials. Also, this December, the tyre company signed an MoU with an Indonesian natural rubber supplier. Yokohama claims that the two companies held a seminar event for small-scale natural rubber farmers in Indonesia.

The sustainability initiatives included in Yokohama Transformation 2023 (YX2023), Yokohama Rubber’s medium-term management plan for fiscal years 2021–2023, are based on the concept of ‘Caring for the Future.’ By implementing sustainability initiatives under this concept, Yokohama Rubber is endeavoring to help resolve social issues through its business activities, states the tyre company.

Japanese chemicals maker Zeon Corporation raised its full-year operating profit forecast after first-quarter earnings more than doubled, driven by robust demand for battery materials and optical films.

The Tokyo-based company, which produces speciality plastics and synthetic rubbers, posted operating income of 12.1 billion yen ($83.3 million) for the three months to June 30, up 136 percent from the previous quarter and 59 percent higher year-on-year.

Net sales declined 2 percent to 103.1 billion yen from a year earlier, affected by yen appreciation and lower elastomer prices reflecting declining raw material costs. However, sales volumes of optical films and battery materials increased during the period.

The company revised its full-year operating income forecast upwards to 30.5 billion yen from a previous estimate of 28 billion yen. However, this still represents a 9 percent decline from the prior year. Full-year sales are now expected to reach 415 billion yen, up 4 percent.

Zeon maintained its annual dividend forecast at 72 yen per share and said it is proceeding with a share buyback programme of up to 10 million shares or 10 billion yen for the current fiscal year.

The speciality materials business, which includes optical plastics, films and battery materials, generated operating income of 7.4 billion yen in the first quarter, jumping 40 percent year-on-year. Sales in the division fell 3 percent to 29.3 billion yen, partly due to timing differences at overseas affiliates related to the Chinese New Year.

Demand for battery materials remained steady, supported by China’s electric vehicle subsidy policies, whilst shipments to the United States energy storage systems market began during the quarter. The company said European EV sales showed signs of recovery, though inventory adjustments were prolonged.

In optical films, shipments increased due to expanded market share in large-sized televisions, whilst demand remained steady for tablet and smartphone applications.

The elastomer business posted operating income of 4.2 billion yen, up 12 percent from a year earlier, though sales were flat at 58.1 billion yen. The division was affected by weak overseas demand and lower selling prices caused by falling raw material costs.

Zeon also announced plans to sell a portion of its investment securities between August 2025 and March 2026, expecting to book a gain of approximately 10.9 billion yen to improve capital efficiency. The move is expected to reduce its cross-shareholdings ratio to around 11-12 percent of net assets by the end of the fiscal year.

The company said it had completed a reorganisation in June, transferring its chemicals business to the speciality materials division to accelerate decision-making and maximise profitability.

For the second half of the year, Zeon cautioned that optical film shipments are expected to decline due to panel production adjustments and seasonal mobile device demand. However, it described the adjustment as temporary with growth anticipated in fiscal 2026.

Continental is redefining adventure riding for a new generation with the launch of the TKC 80², a complete re-imagining of its legendary TKC 80 tyre. After four decades, this isn't a simple update but a fundamental redesign crafted for today's powerful and heavy adventure motorcycles. It answers a clear call from riders who are increasingly drawn to uncharted paths, yet refuse to sacrifice performance on the journey there. The TKC 80² is engineered to be an uncompromising partner for this dual-purpose lifestyle.

Its performance begins with a cleverly engineered tread. The pattern uses larger, strategically shifted blocks that create more biting edges for superior grip in dirt, sand and gravel. This design also actively resists clogging, ensuring consistent performance where other tyres might pack up with mud. Stability is enhanced through a larger contact area, inspiring confidence whether carving a paved corner or navigating a rocky trail. The logic even extends to direction: the front tread is angled to dig in during braking, while the rear is designed in the opposite way to maximise acceleration traction without excessive digging.

Beneath the tread, a new carcass provides the backbone. It is specifically calibrated for a balanced 50/50 use, offering the robust stability needed for a loaded bike at high speeds or on demanding off-road sections while also improving ride comfort through optimised damping. An advanced rubber compound tackles the classic trade-off, delivering aggressive grip across diverse surfaces while also promising remarkable longevity and wear resistance. This is complemented by RainGrip technology, which instils confidence by maintaining secure handling when the weather turns cold and wet.

Built for epic journeys on every continent and backed by robust puncture protection, the TKC 80² is for those who ride without limits. To fit a broad spectrum of modern travel enduros from brands like BMW, KTM and Ducati, it will be produced in multiple sizes. With its distinct new sidewall icon, the Continental TKC 80² will be available at specialist retailers starting in Spring 2026.

Raphael Michels, Product Manager for Motorcycle Tires at Continental, said, “Our new flexible rubber compound adapts perfectly to the micro-roughness of the asphalt, providing excellent grip. At the same time, we’ve worked intensively to resolve the conflict between on- and off-road performance in the best possible way. The tyre tread combines maximum flexibility for safe wet grip with high block stiffness for stability and mechanical grip.”

Christoph Ettenhuber, Head of Business Field Motorcycle Tires at Continental, said, “With the TKC 80², we’re setting new standards in terms of versatility, robustness and off-road performance. The combination of innovative tread design, new rubber compound and optimised carcass offers adventure riders maximum safety, control and riding pleasure on a wide variety of terrains.”

Bridgestone has confirmed a January 2026 launch for its new premium sports motorcycle tyre, the BATTLAX RACING STREET RS12, in North America. Developed under the concept ‘From Circuit to Street,’ this road-legal tyre is engineered to deliver the highest level of dry grip within the BATTLAX lineup by directly incorporating technologies refined in competitive racing.

The RS12 features a specialised compound derived from race tyre development, which works in concert with a newly designed tread pattern. This pattern’s optimised groove ratio enhances overall tyre rigidity and increases the contact area during cornering for superior grip. A significant innovation for the front tyre is the introduction of the HE-MS BELT structure, a technology previously reserved for top-tier global motorcycle races. This flexible belt system equalises contact pressure to provide a further boost in traction.

By integrating these endurance-racing technologies, the RS12 achieves comprehensive performance improvements on the circuit, with a primary focus on dry conditions. The result is a notable reduction in lap times compared to its predecessor, the RS11. Furthermore, the synergistic combination of its compound, pattern and structure ensures that the high grip level is consistently maintained over multiple laps, resisting performance degradation. This gives riders confidence and a more engaging experience across diverse riding scenarios, from aggressive sport riding on dry pavement to tackling winding roads and dedicated track days.
