Across 5 covered model years from 2002 to 2007, the Yamaha PW 50 motorcycle has supplied dry weights ranging from 81.6 lb (37 kg) to 82 lb (37.2 kg).
Yamaha PW 50 weight overview
Its low overall mass should be most noticeable off the throttle: moving it by hand, backing out of a parking space and managing stop-start riding should take less effort than on a heavy road bike. The comparison uses dry weight because a usable wet/running figure was not supplied, so the actual ready-to-ride motorcycle will be heavier.

What the weight numbers tell you
Yamaha PW 50 weight FAQ
What is the Yamaha PW 50 dry weight?
The available dry weight is 81.6 lb (37 kg) to 82 lb (37.2 kg). Actual ready-to-ride weight will be higher after fuel and operating fluids are added.
Which Yamaha PW 50 years have different weight specs?
The supplied data shows different weight figures across the 2002, 2004, 2005, 2006, 2007 model years. Use the year-specific changes section above for the exact value attached to each changed year. No usable dry/wet figure was supplied for 2005.
How much does a full tank add to the Yamaha PW 50?
Based on the supplied 0.5 US gal (1.89 L) to 2.11 US gal (8 L) tank capacity, the gasoline itself weighs about 3.1 lb (1.4 kg) to 13.1 lb (6 kg) when full. This helps explain part of the difference between dry and ready-to-ride mass.
What is the combined Yamaha PW 50 and rider weight?
Using the model’s representative dry weight and a 180 lb rider, the combined bike-and-rider mass is about 261.6 lb (118.6 kg) before riding gear, luggage or a passenger.
What is the Yamaha PW 50 power-to-weight ratio?
Available model-year data produces 3.31 hp per 100 lb. It shows engine output relative to motorcycle mass rather than just quoting peak horsepower.
Is the listed Yamaha PW 50 weight ready to ride?
The published usable figure is dry, not curb weight. A simple dry-plus-full-fuel estimate is 85.1 lb (38.6 kg) to 94.7 lb (43 kg), but that still is not a substitute for an official wet/curb specification.
What is the Yamaha PW 50 full-tank weight estimate?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 85.1 lb (38.6 kg) to 94.7 lb (43 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
What is the Yamaha PW 50 torque per 100 lb of bike weight?
Where compatible torque and weight figures are available, the model works out to 3.44 lb-ft per 100 lb. This gives more context than torque alone because it relates engine twist to the mass it has to move.
How many cc does the Yamaha PW 50 have per pound?
The available figures work out to 0.6 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. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications.
