FJR1300 owners report an impressive fuel economy of around ~42 mpg.
FJR1300’s fuel tank capacity is an impressive 5.8 gallons. This gives the FJR1300 an impressive 220-270 miles range on a full tank.
The four-valve cylinder head design enhances combustion efficiency, contributing to the bike’s exceptional mileage.
FJR1300’s Avg MPG
The Yamaha FJR1300 is regarded as one of the most fuel-efficient sport-touring motorcycles available.
According to owner reports, the average real-world fuel economy ranges from 40-45 mpg in normal riding conditions.
Even when riding aggressively on backroads, fuel efficiency remains excellent at 35-38 mpg.
Contributing to the high mileage is the FJR1300’s advanced electronic fuel injection system which precisely meters fuel based on operating conditions.
The four-valve cylinder head design also boosts combustion efficiency.
Lastly, the overdrive 6th gear keeps RPM low during highway cruising, maximizing efficiency.
Yamaha FJR1300’s Fuel Tank Capacity
All FJR1300 models come equipped with a 5.8-gallon fuel tank.
The generous capacity balances the need for long-range touring capability with the goal of keeping the bike’s weight low.
5.8 gallons strikes an ideal compromise that maintains the FJR1300’s excellent handling while still allowing 250+ miles between fill-ups.
What fuel does a FJR1300 take?
FJR1300 can take 87-octane or 89-octane fuel. The higher the octane number the better.
Fuel Range of FJR1300
Given real-world fuel averages of 40-45mpg, FJR1300 owners can expect a fuel range of 220 to 270 miles from a full 5.8-gallon tank.
This allows riding for 3.5-4 hours between fuel ups during long highway trips.
Even riding aggressively only lowers average fuel economy to 35-38mpg. So, even if you use a heavier throttle, a fuel range of 190-215 miles is guaranteed.
Overall the FJR1300’s 5.8 gallon capacity and engine efficiency combine to deliver excellent cruising range. Riders can comfortably ride several hours on the open road between refueling.
Reasons for FJR1300’s Fuel Efficiency
The FJR1300 features an advanced electronic fuel injection system that uses multiple sensors to precisely regulate fuel delivery based on riding conditions.
This reduces the fuel consumption when full-throttle power is not required.
Additionally, the four-valve cylinder head design boosts combustion efficiency, extracting the maximum energy from every drop of fuel.
The FJR1300 strikes an ideal balance with its 5.8-gallon fuel tank capacity.
On the one hand, the generous tank size ensures a long cruising range between fill-ups, with owners reporting 220-270 miles from a full tank.
Factors That Impact FJR1300’s MPG
The Yamaha FJR1300 is capable of excellent fuel efficiency. However, certain riding habits or conditions can reduce mileage:
- Aggressive Throttle Usage – Wringing the throttle open at every opportunity adds more fuel than necessary for brisk acceleration.
- High-Speed Riding – Cruising above 75 mph substantially increases aerodynamic drag from wind resistance, putting a greater load on the engine.
- Stop-and-Go Traffic – The constant acceleration and braking inherent in congested traffic causes fuel to be dumped during deceleration while acceleration requires excess fuel.
- Heavily Loaded – Packing on one too many accessories or overfilling saddlebags strains the engine since it must work harder to accelerate the additional heft.
- Strong Headwinds – Battling stiff headwinds has a major impact because the engine is pushing against air resistance, using extra effort and fuel to maintain speed.
Tips to Maximize Average MPG of FJR1300
FJR1300 riders can optimize real-world economy through conscientious riding habits:
- Accelerating Smoothly – Work the throttle progressive rather than whacking it open suddenly. Gradual inputs allow measured fuel delivery.
- Shifting Up Early – Without over-revving, change to higher gears soon and ride in lower RPM ranges for less engine effort.
- Maintaining Steady Speed – Find a “sweet spot” RPM range for optimal efficiency based on load and conditions, then govern throttle openings accordingly. FJR1300 has a cruise control system that helps maintain a steady speed, thus increasing the mpg.
- Checking Tire Pressures – Keep tires inflated properly to specification. Under-inflation makes the tire deflect more and as a result, the engine needs to work more.
- Traveling Light – Avoid packing on every possible accessory or overloading saddlebags to prevent taxing the engine with excess baggage weight.
- Route Planning – When possible, choose routes with long downhill stretches and avoid traffic congestion to maximize the miles per tank.
- One can use 87-octane or 89-octane fuel in the FJR1300.
Although unmodified FJR1300s already deliver stellar mileage, popular bolt-on mods like these can further improve efficiency:
- ECU Reflashing – Upload tuned mapping to refine fuel trim settings and ignition timing for using less fuel.
- Low-Friction Lubricants – Special full-synthetic low-drag oils allow easier piston movement and reduce internal friction.
- Gearing Adjustments – Swap sprockets to alter final drive ratios for lower RPM touring speeds with similar road performance.
- Exhaust System Upgrades – Install headers and slip-on mufflers engineered to reduce engine backpressure and pumping losses.
FJR1300 Fuel Pump not working?
There could be many reasons why the fuel pump fails to function properly in the FJR1300.
Check the kill switch, ignition switch, and various relays that support the fuel pump.
Check for any wiring complications at the fuel pump plug.
Check if the fuel injection system and the electrical connections to it are working properly.
Inspect the lean angle switch to see if it’s working properly.
The fuel pump fails to function properly when the fuse responsible for the fuel pump gets blown.
