Across 4 covered model years from 2002 to 2006, the Yamaha PW 80 motorcycle has a listed dry weight of 125.7 lb (57 kg).
Yamaha PW 80 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 80 weight FAQ
What is the Yamaha PW 80 dry weight?
The available dry weight is 125.7 lb (57 kg). Actual ready-to-ride weight will be higher after fuel and operating fluids are added.
Which Yamaha PW 80 years have different weight specs?
No clear weight change appears in the usable model-year data. Other specifications may still differ by year.
How much does a full tank add to the Yamaha PW 80?
Based on the supplied 1.3 US gal (4.92 L) to 2.11 US gal (8 L) tank capacity, the gasoline itself weighs about 8.1 lb (3.7 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 80 and rider weight?
Using the model’s representative dry weight and a 180 lb rider, the combined bike-and-rider mass is about 305.7 lb (138.6 kg) before riding gear, luggage or a passenger.
Is the listed Yamaha PW 80 weight ready to ride?
The published usable figure is dry, not curb weight. A simple dry-plus-full-fuel estimate is 138.8 lb (63 kg), but that still is not a substitute for an official wet/curb specification.
What is the estimated Yamaha PW 80 weight with a full tank of gas?
Filling the listed tank brings the calculated bike weight to roughly 138.8 lb (63 kg). This estimate is most useful when no official wet/running figure is available.
How much of the Yamaha PW 80 total weight comes from fuel?
The calculated full-tank fuel mass is about 10.5% of the bike’s listed weight. This helps show why a dry-weight number can understate what you actually manage on the road.
How does Yamaha PW 80 torque compare with its weight?
Where compatible torque and weight figures are available, the model works out to 3.7 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 PW 80 engine-size-to-weight ratio?
The available figures work out to 0.63 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.
