Yamaha TDM 850 weight FAQ
What does the Yamaha TDM 850 weigh ready to ride?
The supplied figures span 507.1 lb (230 kg) to 517 lb (234.5 kg) for wet/running weight and 436.5 lb (198 kg) to 443.1 lb (201 kg) for dry weight across the years in this page. Wet weight is the better guide to what you actually manage on the road.
Is the Yamaha TDM 850 heavy compared with other Yamaha allround models?
Relatively speaking, it is on the heavier side. The model sits near the 86th weight percentile in its Yamaha category, so it is heavier than most of the compatible comparison set.
Does the Yamaha TDM 850 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 TDM 850 fuel weigh?
The listed tank capacity is 4.76 US gal (18 L) to 5.28 US gal (20 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 29.6 lb (13.4 kg) to 32.8 lb (14.9 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha TDM 850 with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 687.1 lb (311.6 kg) using the representative wet/running figure. Gear and luggage would add more.
How much horsepower does the Yamaha TDM 850 have per 100 lb?
Where compatible power and weight figures are available, it works out to 17.55 hp per 100 lb to 18.05 hp per 100 lb. That places it around the 82nd percentile within the compatible Yamaha allround power-to-weight comparison.
What is the estimated Yamaha TDM 850 weight with a full tank of gas?
Based on the available dry-weight and tank-capacity data, a full-tank estimate is 468.3 lb (212.4 kg) to 469.4 lb (212.9 kg). Oil, coolant and market-specific equipment can still make actual ready-to-ride weight different.
How much torque does the Yamaha TDM 850 have per 100 lb?
The calculated torque-to-weight range is 11.41 lb-ft per 100 lb to 13.86 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
What is the Yamaha TDM 850 displacement per pound?
Engine displacement relative to bike weight is 1.64 cc per lb to 1.94 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Motorcycle specifications can vary by model year, market, equipment and the exact dry/curb-weight definition.
