Detailed Product Description
(Part Number: B5X-E7641-00, official factory replacement for superseded part B74-E7641-00).
Manufactured to Yamaha's strict OEM quality and dimensional standards, this genuine replacement V-belt features high-tensile aramid fiber reinforcement cords embedded in a heat-resistant rubber compound. It maintains exact sidewall angle geometry and lateral rigidity to prevent belt rollover and heat buildup under heavy throttle loads. Universally compatible with all model years from 2017 through 2026—including first-generation models (2017–2022), facelift editions (2023–2024 BKA series), and the latest models (2025–2026 BSS series and Tech MAX)—it installs cleanly with zero modifications required.
Complete 2017–2026 Model Year Compatibility: Direct OEM fitment across all first-generation and next-generation Yamaha XMAX 300 and XMAX 250 platforms.
