Overview[edit | edit source]
Honda MSX 125
The MSX125 is powered by a 125cc
air-cooled two-valve single-cylinder engine with
Hondas PGM-FI
fuel injection system inherited from the Honda
Wave 125i underbone motorcycle thats 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.
