High-Capacity Radiator for FORCE 155, SMAX

Applicable models: YAMAHA FORCE 155 / S-MAX 155. Color: Black. Thickness (OEM / KOSO): 23mm / 23mm. Cooling water pipes (OEM / KOSO): 22 rows / 23 rows. Cooling fins (OEM / KOSO): 23 rows / 24 rows. Product manual.

※ Increased cooling water pipes and cooling fins to increase coolant capacity. ※ Cooling pipe routing increased by 5% to effectively improve heat dissipation efficiency; cooling fin area increased by 5%. ※ Micro-structure opening design on the cooling fins increases heat dissipation efficiency without increasing the radiator size. ※ 3D CARBON texture design for enhanced aesthetics. ※ Geometric design for upper and lower water tanks. ※ Uses high-grade engineering plastic for high temperature resistance, hydrolysis resistance, and impact resistance. ※ Shock-absorbing elastomer cushions ensure radiator durability and reduce engine vibration damage to the radiator structure. ※ Plastic and aluminum alloy combination achieves a lightweight design. ※ Same mounting points as OEM, no modifications required, direct bolt-on (non-destructive installation). ※ Improved cooling and heat dissipation efficiency, suitable for modified big bore cylinders / high compression pistons / lightweight cooling fans. ※ Optimized heat dissipation area design prevents overcooling, which could cause thermal efficiency loss, ensuring optimal engine operating temperature. - Origin - KOSO was officially established due to the necessity of having an independent brand for future market marketing. In 1989, KOSO was registered as a trademark for Tong Ya. The name KOSO is derived from the Japanese words for "conception" and "high speed"; conception represents creativity, while high speed represents high performance. Combined, it reflects the company's desire to use creativity to create high-performance products! - Spirit - The brand spirit pursued by KOSO is to build quality, technology, and service on the foundation of integrity and mutual trust. We persistently hold this attitude, not only manufacturing high-quality products but also pursuing product innovation and quality improvement, hoping to bring more excellent products to everyone. - Brand Journey - Pursuing perfect product design and quality has always been our goal. Therefore, KOSO constantly pushes itself by improving its own technology. We firmly believe that brand image and product quality are synonymous! Therefore, the company has strict requirements for product development, production processes, and quality control, hoping to achieve the goal of high quality while stepping onto the world stage. In the future, KOSO will continue to develop more user-friendly and innovative products, and hopes to become the next world number one from Taiwan within ten years, another pride of Taiwan. - Exhibitions and Certifications - Tong Ya Electronic began exhibiting in Italy in 2001, gradually stepping onto the international stage, bringing KOSO's dedication and professionalism to the world, and striving to convey an image of high quality and innovation. It obtained TS16949 international certification in 2007, and ISO 14001 and ISO 45001 international certifications in 2024. In the future, it will continue to create more compelling products. Every product launch requires actual installation testing, which is the strictest form of quality inspection. No matter how well a product is designed, actual installation and use is the ultimate test of quality. To further improve quality and actual product testing, we participate in international competitions. Every award is an affirmation of our products because they are modifications that do not allow for errors. We are so rigorous about quality. Test reports and product measurement charts are also our demonstration of the results of customer installations. It is because of this caution that our products can show better quality time after time. - Equipment and Checkpoints - Our pre-inspection for every product uses the most advanced technical machinery, setting different conditions to simulate and conduct tests, such as vibration tests, waterproof tests, etc. All partner manufacturers who have participated in the inspection process agree with our principles of quality control and trust the test results. What is valuable is that while the products are subjected to tests like passing through checkpoints, we also add different conditions and make adjustments based on actual environments, combined with user-friendly operations to present the most realistic tests for the products and the quality improved after corrections.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.

[Notes before ordering] Before ordering, please confirm the color, size, and other information you wish to purchase. Most products have delivery times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment. If an order cannot be established due to manufacturer stock shortages or temporary inability to deliver, it will not be processed; no fees will be charged if the order is not established. Please understand that manufacturers may unilaterally change specifications or exterior designs, which may result in packaging or product appearance differing from the images on the product page. If a manufacturer's unilateral change in product design or specifications results in the product failing to perform as expected at the time of order, please consult our customer service for follow-up processing. Products go through multiple shipping processes from order to delivery, so packaging may be deformed or damaged during transport, but the product itself remains intact and usable. [Return Notes] If you need return services, please apply in the return section; please keep the product appearance and use the original packaging box for sealing. Upon receiving your return request, we will arrange for a logistics provider to collect the goods as soon as possible. For non-human damage defects, please apply for a return within 7 days of receiving the product. [Authenticity Guarantee] For products with an authenticity guarantee, if they are found to be suspected counterfeits and are confirmed by court judgment after relevant litigation, a 10-fold compensation of the original purchase price will be provided to the customer who purchased the product.
