Compared with similar Yamahas in this dataset, it is heavier than about 83.7% of 129 scooters using the same weight basis.
Which Yamaha X-MAX 400 years have different weight specs?
The supplied data shows different weight figures across the 2014-2017 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 X-MAX 400?
Based on the supplied 3.7 US gal (14 L) tank capacity, the gasoline itself weighs about 23 lb (10.4 kg) when full. On models with a wet/running weight, that fuel mass is already included in the listed ready-to-ride figure.
What is the combined Yamaha X-MAX 400 and rider weight?
Using the model’s representative wet/running weight and a 180 lb rider, the combined bike-and-rider mass is about 645.2 lb (292.6 kg) before riding gear, luggage or a passenger.
What is the Yamaha X-MAX 400 power-to-weight ratio?
Available model-year data produces 6.69 hp per 100 lb. It shows engine output relative to motorcycle mass rather than just quoting peak horsepower. That places it around the 81st percentile within the compatible Yamaha scooter power-to-weight comparison.
How much of the Yamaha X-MAX 400 total weight comes from fuel?
The calculated full-tank fuel mass is about 4.9% to 4.9% of the listed motorcycle weight. Because the available basis is wet/running weight, that fuel is already included in the ready-to-ride figure.
How does Yamaha X-MAX 400 torque compare with its weight?
Where compatible torque and weight figures are available, the model works out to 5.36 lb-ft per 100 lb to 5.6 lb-ft per 100 lb. This gives more context than torque alone because it relates engine twist to the mass it has to move.
What is the Yamaha X-MAX 400 engine-size-to-weight ratio?
The available figures work out to 0.83 cc per lb to 0.85 cc per lb. This is not a performance rating, but it is a useful way to compare engine size against total motorcycle mass.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
