The Pioneer of Clutchless Touring
The Yamaha FJR 1300 AS (RP13AS) holds a significant place in motorcycling history as the first mass-production sport-tourer to successfully implement the Yamaha Chip Controlled Shift (YCC-S) system. Unlike traditional semi-automatics, the RP13AS retained a standard five-speed gearbox but replaced the manual clutch lever with an electronically controlled hydraulic actuator. This engineering feat allowed riders to shift gears via a traditional foot lever or handlebar-mounted triggers, providing a seamless transition between high-performance sport riding and effortless long-distance touring.
Technical Engineering Insights
The RP13AS is powered by a 1,298cc inline-four engine, renowned for its linear power delivery and exceptional reliability. The YCC-S system integrates with the ECU to monitor engine RPM, throttle position, and gear selection to ensure smooth engagement. From a technical standpoint, the RP13AS also introduced improved cooling systems and adjustable ergonomics (seat and handlebars) compared to its predecessors, making it a benchmark for the ‘Supersport Tourer’ category.
Maintenance Protocol
Lubrication System
For the RP13AS, maintaining oil quality is paramount due to the hydraulic demands of the YCC-S system components. Use a high-quality SAE 10W-40 synthetic or semi-synthetic oil. The system requires 4.0 liters for a full change including the filter. Ensure the oil meets JASO MA standards to prevent clutch slippage.
Chassis and Tires
The FJR’s weight and torque profile necessitate precise tire management. The 120/70 ZR 17 (Front) and 180/55 ZR 17 (Rear) must be maintained at 2.5 bar (36 psi) and 2.9 bar (42 psi) respectively to ensure high-speed stability and prevent cupping.
Electrical & Ignition
The GT14B-4 battery is the heart of the RP13AS electrical system, providing the necessary amperage for the YCC-S actuators. For ignition, the NGK CPR8EA-9 spark plugs should be inspected every 10,000 km to maintain optimal combustion efficiency and throttle response.
Editor’s Verdict
The Yamaha FJR 1300 AS (RP13AS) remains a masterclass in touring engineering. While the YCC-S system requires a specific maintenance mindset, the reward is a machine that offers unparalleled comfort without sacrificing the mechanical soul of a sportbike. For the high-mileage rider, the RP13AS is not just a motorcycle; it is a precision instrument designed for trans-continental dominance.
