Yamaha TT-R 125 E weight FAQ
How heavy is the Yamaha TT-R 125 E?
Listed dry weight is 179 lb (81.2 kg) to 185 lb (83.9 kg). Because no usable wet/running figure was supplied, treat that as a lower starting point rather than the exact on-road weight.
Is the Yamaha TT-R 125 E heavy compared with other Yamaha enduro/off-road motorcycles?
It is on the lighter side in this dataset. Its representative dry weight sits around the 15th weight percentile among 24 Yamaha enduro/off-road motorcycles, meaning most compatible models are heavier.
Does the Yamaha TT-R 125 E 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 TT-R 125 E fuel weigh?
The listed tank capacity is 1.74 US gal (6.58 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 10.8 lb (4.9 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha TT-R 125 E with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 362 lb (164.2 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Yamaha TT-R 125 E dry weight as curb weight?
No. The usable figure is dry weight, so it excludes at least some operating fluids. Dry weight plus the estimated full fuel load is about 189.8 lb (86.1 kg) to 195.8 lb (88.8 kg), and oil/coolant or definition differences may add more.
What is the Yamaha TT-R 125 E full-tank weight estimate?
Using the listed dry weight plus the calculated fuel mass, the estimated weight with a full tank is 189.8 lb (86.1 kg) to 195.8 lb (88.8 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 TT-R 125 E have per pound?
Engine displacement relative to bike weight is 0.67 cc per lb to 0.69 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
