Is the Yamaha WR250X lighter or heavier than other Yamaha supermoto bikes?
It is comparatively light for this Yamaha category. The model lands near the 21st percentile for weight in the compatible dataset.
Which Yamaha WR250X years have different weight specs?
The supplied data shows different weight figures across the 2008-2015 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 WR250X?
Based on the supplied 1.9 US gal (7.19 L) to 2 US gal (7.57 L) tank capacity, the gasoline itself weighs about 11.8 lb (5.4 kg) to 12.4 lb (5.6 kg) when full. This helps explain part of the difference between dry and ready-to-ride mass.
What is the combined Yamaha WR250X and rider weight?
Using the model’s representative wet/running weight and a 180 lb rider, the combined bike-and-rider mass is about 480 lb (217.7 kg) before riding gear, luggage or a passenger.
What is the Yamaha WR250X power-to-weight ratio?
Available model-year data produces 10.03 hp per 100 lb. It shows engine output relative to motorcycle mass rather than just quoting peak horsepower. That places it around the 39th percentile within the compatible Yamaha super motard power-to-weight comparison.
What is the estimated Yamaha WR250X weight with a full tank of gas?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 292.4 lb (132.6 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
What is the Yamaha WR250X torque per 100 lb of bike weight?
Where compatible torque and weight figures are available, the model works out to 5.79 lb-ft per 100 lb to 5.83 lb-ft per 100 lb. This gives more context than torque alone because it relates engine twist to the mass it has to move.
