The new 2025 YZF-R9 was conceived to redefine the supersport class by combining track-capable performance with street bike accessibility through a broad, smooth power delivery, light handling, street-friendly ergonomics and a complete package of advanced rider aids. A machine as at home on a race circuit in the hands of a seasoned track rider as it is exploring twisty roads or urban streets in the hands of a dedicated road rider.
Based on Yamaha’s renowned CP3 powerplant, the new 2025 YZF-R9 boasts a dedicated supersport chassis and comprehensive electronics suite, wrapped in striking next-generation R-series styling.
