Description
Product Overview
High-performance repair solution specifically designed for the 18-pin ignition system of the second-generation Yamaha YZF-R1 (2002-2003 model). This three-piece kit includes a high-performance 18-pin stator coil, a precision-fit gasket, and a matching rectifier, precisely tuned to the 18-pin engine configuration of the R1 (2002-2003). Optimized for increased power efficiency and improved throttle response, it resolves the charging instability issues of aging 18-pin systems and restores the quick and precise responsiveness of this 1000cc sport motorcycle. Key Benefits: • Perfect compatibility with the 18-pin system: Designed specifically for the legendary 18-pin ignition system of the R1 (2002-2003), it guarantees optimal performance, unlike generic 16- or 12-pin products. • Improved high-rpm performance: The coil is optimized for the R1's operating conditions above 10,000 rpm. Its heat dissipation and insulation exceed the original specifications and meet the demands of sporty track riding. • Original data restoration: The coil has been precision-manufactured to exactly replicate the phase, resistance, and output voltage curves of the original 18-pole coil, ensuring accurate readings from the ECU. • System integration and adaptation: The rectifier's internal parameters are optimized for the high-frequency AC output of the 18-pole system, ensuring efficient conversion and precise voltage regulation. Compatible models and main specifications: Yamaha YZF-R1: 2002 and 2003 models. Main feature: 18-pole magnetic motor system. *Important: Only compatible with 2002–2003 R1 models that were originally equipped with an 18-pole magnetic motor. R1 models from model years 2000–2001 are mostly equipped with a 16-pin system. Models from 2004 onwards have different designs. Please check this using the original part number, the appearance of the magnetic motor (number of visible poles), or repair invoices.*
