Yamaha PW50 weight FAQ
What does the Yamaha PW50 weigh ready to ride?
The supplied figures span 85.1 lb (38.6 kg) to 90.4 lb (41 kg) for wet/running weight and 82 lb (37.2 kg) for dry weight across the years in this page. Wet weight is the better guide to what you actually manage on the road.
Does the Yamaha PW50 weight change by model year?
Not every covered year uses the same figure. The page groups identical values together and lists the later model years where the supplied weight specification changes.
How much does the Yamaha PW50 fuel weigh?
The listed tank capacity is 0.5 US gal (1.9 L) to 0.53 US gal (2.01 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 3.1 lb (1.4 kg) to 3.3 lb (1.5 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha PW50 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 266 lb (120.6 kg) using the representative wet/running figure. Gear and luggage would add more.
What is the estimated Yamaha PW50 weight with a full tank of gas?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 85.1 lb (38.6 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
How many cc does the Yamaha PW50 have per pound?
Engine displacement relative to bike weight is 0.54 cc per lb to 0.6 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Will the Yamaha PW50 feel heavy at low speed?
Its low mass should make hand-moving and parking easier than on most full-size road motorcycles. Seat height and center of mass can still change how manageable it feels.
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. Confirm critical figures in the owner’s manual or on the official Yamaha Motorsports website.
