Yamaha BWs Naked 50 weight FAQ
How heavy is the Yamaha BWs Naked 50?
Listed dry weight is 183 lb (83 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
Is the Yamaha BWs Naked 50 heavy compared with other Yamaha scooters?
It is on the lighter side in this dataset. Its representative dry weight sits around the 10th weight percentile among 47 Yamaha scooters, meaning most compatible models are heavier.
Does the Yamaha BWs Naked 50 weight change by model year?
Not in the usable weight data on this page. Across the covered 2013-2014 years, the supplied weight figure remains the same where comparable values are available.
How much does the Yamaha BWs Naked 50 fuel weigh?
The listed tank capacity is 1.4 US gal (5.3 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 8.7 lb (3.9 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha BWs Naked 50 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 363 lb (164.6 kg) using the representative dry figure. Gear and luggage would add more.

Can I treat the Yamaha BWs Naked 50 dry weight as curb weight?
No. The usable figure is dry weight, so it excludes at least some operating fluids. Dry weight plus the estimated full fuel load is about 191.7 lb (86.9 kg), and oil/coolant or definition differences may add more.
What does the Yamaha BWs Naked 50 weigh with a full tank?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 191.7 lb (86.9 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
What is the Yamaha BWs Naked 50 torque per 100 lb of bike weight?
The calculated torque-to-weight range is 1.45 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
