Overview
The Yamaha MT 125 is a naked motorcycle produced from 2015 through 2023. For 2023, its 124.7 cm³ liquid-cooled single-cylinder four-stroke engine produces 15 hp (11 kW) and 11.5 Nm of torque at 8,000 rpm; wet weight is 142 kg.
The 810 mm seat gives the rider an elevated perch, which can make getting both feet firmly down harder for shorter riders. Fuel consumption is 2.10 liters/100 km, and the 11-liter tank gives an estimated range of about 524 km; the 2022 model year increased tank capacity from 10 liters to 11 liters. Torque peaks at 8,000 rpm, so reaching that peak means revving the engine, while the assist and slipper clutch helps calm the rear wheel during hard downshifts.

Pros and cons
Advantages
Long estimated range
The 11-liter tank and 2.10 liters/100 km fuel consumption work out to an estimated range of about 524 km between fill-ups.
Slipper clutch
The assist and slipper clutch helps reduce rear-wheel disturbance during hard downshifts.
Things to consider
High seat
At 810 mm, the seat may make it harder for shorter riders to plant both feet at a stop.
Torque comes high in the rev range
Peak torque arrives at 8,000 rpm, so riders need to rev the engine to reach its torque peak.
Chain final drive
The chain needs periodic cleaning, lubrication, and adjustment.

How to measure
Stand barefoot with your back to a wall. Hold a book firmly between your legs, then measure from the floor to the top edge of the book.
Estimated ground reach
Both feet likely flat
You should have a stable stance at a stop, although seat width and suspension setup still matter.
