Overview
The Yamaha XT 125X is a supermoto produced from 2006 to 2009. The 2009 model has a 124 cm³, air-cooled, four-stroke single producing 9.8 hp (7.3 kW) and 10.1 Nm of torque; it weighs 120 kg wet and 106 kg dry.
At 860 mm, the seat is relatively tall and can make getting a foot down harder for shorter riders. The 120 kg wet weight keeps low-speed maneuvering manageable, while 190 mm of ground clearance and 175 mm front and 190 mm rear wheel travel help with rough pavement. Torque increased from 9.5 Nm in 2008 to 10.1 Nm in 2009, while the seat rose from 830 mm to 860 mm and the tank shrank from 10 liters to 9 liters, leaving less fuel aboard between fill-ups. The chain final drive needs periodic cleaning and adjustment.

Pros and cons
Advantages
Manageable wet weight
At 120 kg wet, the XT 125X is relatively easy to maneuver at low speeds.
Room over bumps
Its 190 mm of ground clearance helps keep the underside clear over uneven surfaces.
Things to consider
Tall seat
The 860 mm seat height can make it difficult for shorter riders to plant both feet at a stop.
Smaller tank
The 9-liter tank holds 1 liter less than the 2008 model, leaving less fuel aboard between fill-ups.
