Overview
The Yamaha YZF R 125 is a sportbike produced from 2008 to 2016. For 2016, it uses a 124.7 cm³ single-cylinder, four-stroke engine producing 15 hp (11 kW) and 12.2 Nm of torque at 8,000 RPM; its wet weight is 140.0 kg.
The 818 mm seat height puts the rider relatively high, which can make it harder for shorter riders to reach the ground at stops. The 11.50-liter tank is smaller than the 13.80-liter tank introduced before the 2014 model year, while rear spring preload adjustment lets the suspension be tailored to the load; the chain final drive needs cleaning and adjustment.

Things to consider
Tall seat
At 818 mm, the seat may make it harder for shorter riders to get both feet down at stops.

The 11.50-liter tank is reduced from the 13.80-liter capacity used before 2014.
Chain upkeep
The chain final drive needs periodic cleaning and adjustment.
