2013 Sherco 125 ST

Posted on by  

The Sherco 125 St shares many elements with its bigger sibling, the St 2.9. Like its brother, the Sherco 125 ST was designed with agility in mind and is built on a modern chassis.

The bike is equipped with a 125 cc, two stroke engine that has received a series of improvements which make it better suited for the requirements of today’s riders. The motorcycle’s clutch was also improved as well as the carburetor and brakes which now features hydraulically activated, floating 185 mm front and 145 mm rear discs.

The engine’s power is kept under control by a 5 speed sequential gearbox which features a security selector system to prevent false shifts.

The motorcycle rides on a front Tech Ø 39 mm hydraulic telescopic fork (165 mm travel ) and a rear progressive link system with a single adjustable shock absorber ( 175 mm travel).

This bike is almost a twin to her sister ST 2.9 which differs externally by the larger size of the crown and the small size of the cylinder. In addition to incorporating all the new series already presented in the ST, the small 125 cm3 engine has undergone some minor adjustments that increase efficiency and provides unmatched acceleration capability. This achieves the speed of 16,000 revolutions / minute while preserving the qualities of the engine at low speed, essential for trial.

For the chassis, the ST 1.25 is equipped with the best equipment in the ST range, including Formula frain kit developed in close collaboration with the technical department Sherco, the adjustable foot rests, new suspension settings and adjustments in the driving position.
