Yamaha XT125X weight FAQ
What does the Yamaha XT125X weigh ready to ride?
The supplied figures span 264.6 lb (120 kg) for wet/running weight and 233.7 lb (106 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 XT125X heavy compared with other Yamaha supermoto bikes?
It is on the lighter side in this dataset. Its representative wet weight sits around the 10th weight percentile among 21 Yamaha supermoto bikes, meaning most compatible models are heavier.
Does the Yamaha XT125X weight change by model year?
Not in the usable weight data on this page. Across the covered 2008-2009 years, the supplied weight figure remains the same where comparable values are available.
How much does the Yamaha XT125X fuel weigh?
The listed tank capacity is 2.38 US gal (9 L) to 2.64 US gal (10 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 14.8 lb (6.7 kg) to 16.4 lb (7.5 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha XT125X with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 444.6 lb (201.6 kg) using the representative wet/running figure. Gear and luggage would add more.
How much horsepower does the Yamaha XT125X have per 100 lb?
Where compatible power and weight figures are available, it works out to 3.7 hp per 100 lb. That places it around the 11th percentile within the compatible Yamaha super motard power-to-weight comparison.
How heavy is the Yamaha XT125X after filling the fuel tank?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 250.1 lb (113.5 kg). That still may not equal official curb weight because dry-weight definitions can exclude other fluids or equipment.
What is the Yamaha XT125X torque per 100 lb of bike weight?
The calculated torque-to-weight range is 2.82 lb-ft per 100 lb to 3 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
How many cc does the Yamaha XT125X have per pound?
Engine displacement relative to bike weight is 0.47 cc per lb to 0.53 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. Calculated fuel-weight and ratio figures on this page are estimates derived from the supplied specifications.
