2011 Honda PCX 125, 2011 HONDA PCX125 At about 100 miles to the gallon it only makes sense to own one! Perfect for the College Student and an excellent 2nd bike to have for quick around town trips to the store and back.That 125cc motor is a liquid-cooled, fuel-injected, single overhead cam design with an 11.0:1 compression ratio. Hondas V-Matic automatic transmission gets power to the rear wheel. The frame is steel tubing with a unit-construction swingarm and the wheelbase is a lengthy 51.4 inches. Wheels are 14-inchers with skinny bias-ply tires, a 90/90-14 in front and 100/90-14 in back. Braking is handled by a 220mm disc and three-piston caliper in front, and a drum in back. For a twist, theres an interesting combined braking system on the PCX. The rear drum is linked to the front three-piston caliper with a delay-spring mechanism that prevents the front brake from being activated before the rear, maximizing braking by evenly distributing stopping force between the front and rear wheels.
