Is the Yamaha FZS lighter or heavier than other Yamaha naked bikes?
It is comparatively light for this Yamaha category. The model lands near the 18th percentile for weight in the compatible dataset.
Which Yamaha FZS years have different weight specs?
The supplied data shows different weight figures across the 2009 and 2017 model years. Use the year-specific changes section above for the exact value attached to each changed year.
How much does a full tank add to the Yamaha FZS?
Based on the supplied 3.17 US gal (12 L) to 3.7 US gal (14 L) tank capacity, the gasoline itself weighs about 19.7 lb (8.9 kg) to 23 lb (10.4 kg) when full. This helps explain part of the difference between dry and ready-to-ride mass.
What is the combined Yamaha FZS and rider weight?
Using the model’s representative wet/running weight and a 180 lb rider, the combined bike-and-rider mass is about 479.8 lb (217.6 kg) before riding gear, luggage or a passenger.
What is the Yamaha FZS power-to-weight ratio?
Available model-year data produces 4.64 hp per 100 lb. It shows engine output relative to motorcycle mass rather than just quoting peak horsepower. That places it around the 13th percentile within the compatible Yamaha naked bike power-to-weight comparison.
What is the estimated Yamaha FZS weight with a full tank of gas?
Filling the listed tank brings the calculated bike weight to roughly 300.8 lb (136.4 kg). This estimate is most useful when no official wet/running figure is available.
How much weight do fuel and fluids add to the Yamaha FZS?
Where both figures are available, the listed wet-versus-dry difference is about 24.3 lb (11 kg). That gap reflects fuel and operating fluids, plus any differences in how the source defines dry and running weight.
How much of the Yamaha FZS total weight comes from fuel?
The calculated full-tank fuel mass is about 6.6% to 7.6% of the bike’s listed weight. This helps show why a dry-weight number can understate what you actually manage on the road.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications.
