Aprilia is carrying on its proud tradition of building high-end small-displacement mounts this year, with a redesign of its SX 125 and RX 125, its foreign-market 125cc, four-stroke SuperMotard and dirt bike.
The tiny thumper that powers the little beasts gets a rethought top end this year, thanks in part to new Euro 5 emissions regulations. Aprilia says it raised the intake to feed air more directly to the all-new head, which sports revised cams and a new combustion chamber. The exhaust is also entirely new, featuring a new catalytic converter and muffler. The result is a wider torque curve and peak power lower down the rev range. No more wringing your 125′s neck to get it moving.
The Bosch ABS brakes get new gadetry too, to keep the front wheel from locking up and the rear wheel from lifting under heavy braking. The SX gets a 300mm disc up front backed with a 220mm unit out back, while the RX gets a 260mm front rotor backed with the same 220mm rear disc.
The little bikes both get 41mm inverted forks with 240mm (9.4 inches) of travel, and a single shock out back with 210mm (8.3 inches) of rear wheel travel. The SX wears 17-inch spoked wheels with black rims, while the RX gets a 21-inch front wheel and 18-inch rear wheel.

Unfortunately, it doesn’t look like Noale has plans to bring the little Aprilias to these shores.
