Yamaha IT weight overview
This sits in a fairly light weight range. That does not guarantee easy handling, but it reduces the sheer mass you have to manage at a stop. 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 IT weight FAQ
How heavy is the Yamaha IT?
Listed dry weight is 250 lb (113.4 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 IT heavy compared with other Yamaha motorcycles?
It sits fairly close to the middle of the category. Its representative dry weight is around the 40th percentile among 110 compatible Yamaha motorcycles.
How much does the Yamaha IT fuel weigh?
The listed tank capacity is 3.17 US gal (12 L). Using approximately 0.745 kg/L gasoline, a full tank is roughly 19.7 lb (8.9 kg). That is an estimate for fuel mass, not an official Yamaha curb-weight calculation.
How heavy is the Yamaha IT with an average-size rider?
A 180 lb rider brings the simple bike-plus-rider total to roughly 430 lb (195 kg) using the representative dry figure. Gear and luggage would add more.
Can I treat the Yamaha IT 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 269.7 lb (122.3 kg), and oil/coolant or definition differences may add more.
What is the Yamaha IT torque-to-weight ratio?
The calculated torque-to-weight range is 11.86 lb-ft per 100 lb. It is useful for comparing bikes with very different overall weights.
How large is the Yamaha IT engine for its weight?
Engine displacement relative to bike weight is 1.59 cc per lb. It can help compare motorcycles from very different displacement classes without relying on cc alone.
Is the Yamaha IT above or below the typical Yamaha motorcycle weight?
The model sits about 41 lb (18.6 kg) lighter than the compatible median Yamaha motorcycle weight used on this page.
Will the Yamaha IT 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.
