For the 2010 model year, the Yamaha BWs 12 motorcycle has a listed dry weight of 180.8 lb (82 kg).
Yamaha BWs 12 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.

Yamaha BWs 12 weight FAQ
What is the Yamaha BWs 12 dry weight?
The available dry weight is 180.8 lb (82 kg). Actual ready-to-ride weight will be higher after fuel and operating fluids are added.
Is the Yamaha BWs 12 lighter or heavier than other Yamaha motorcycles?
It is comparatively light for this Yamaha category. The model lands near the 13th percentile for weight in the compatible dataset.
How much does a full tank add to the Yamaha BWs 12?
Based on the supplied 1.4 US gal (5.3 L) tank capacity, the gasoline itself weighs about 8.7 lb (3.9 kg) when full. This helps explain part of the difference between dry and ready-to-ride mass.
What is the combined Yamaha BWs 12 and rider weight?
Using the model’s representative dry weight and a 180 lb rider, the combined bike-and-rider mass is about 360.8 lb (163.6 kg) before riding gear, luggage or a passenger.
Is the listed Yamaha BWs 12 weight ready to ride?
The published usable figure is dry, not curb weight. A simple dry-plus-full-fuel estimate is 189.5 lb (85.9 kg), but that still is not a substitute for an official wet/curb specification.
How much heavier is the Yamaha BWs 12 with a full tank?
Filling the listed tank brings the calculated bike weight to roughly 189.5 lb (85.9 kg). This estimate is most useful when no official wet/running figure is available.
How much of the Yamaha BWs 12 total weight comes from fuel?
The calculated full-tank fuel mass is about 4.8% 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 BWs 12 torque compare with its weight?
Where compatible torque and weight figures are available, the model works out to 1.47 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 BWs 12 engine-size-to-weight ratio?
The available figures work out to 0.27 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.
