The MSX125 is powered by a 125cc air-cooled two-valve single-cylinder engine with Honda‘s PGM-FI fuel injection system inherited from the Honda Wave 125i underbone motorcycle that’s popular in Asian markets. Honda claims an output of 9.7 hp at 7000 rpm and 8.0 ft-lb. at 5,500 rpm.

The engine has some low-friction features such as an offset cylinder and roller-rocker arms. This should help the MSX125 provide good fuel economy,

Power is delivered through a four-speed transmission and chain drive to the 12-inch aluminum rear wheel. the small diameter also highlights the thickness of the 120/70-12 front and 130/70-12 rear tires. The front wheel has a two-piston brake caliper gripping a 220mm disc while a single-piston caliper grips a 190mm disc at the rear. Suspension is provided by a 31mm upside-down fork, a first for a 125cc Honda, and a rear monoshock.

Honda registered four new patents in develop the MSX125, specifically related to the split structure tank cover and the steel mono-backbone frame. The split structure allowed Honda engineers to position the PGM-FI components and other electrical parts inside the tank cover without compromising the capacity of the 1.45 gallon fuel tank.

Other features include a projector headlight, LED taillight and an LCD displaying speed, twin trip meters, fuel gauge and clock. The seat is a low 30.1 inches off the ground, suitable for the MSX125′s target market. Also helpful is the claimed curb weight of 224 pounds.
