2001 Husqvarna CR125 – Italian Two-Stroke Character in the 125 Class

The 2001 Husqvarna CR125 was an evolutionary model rather than a completely new generation. It continued Husqvarna's established small-bore motocross platform with the familiar liquid-cooled 125cc two-stroke engine, six-speed transmission, steel chassis and European suspension package. For riders used to the Japanese 125s of the period, the Husky offered something noticeably different in both appearance and riding character.

At the centre of the bike was the 124.8cc reed-valve two-stroke fed by a 38 mm Mikuni TMX carburettor. Like most competition 125s, the engine rewarded riders who kept it spinning in the upper part of the rev range. Correct carburettor condition and jetting remain important on surviving examples, and owners dealing with worn or modified induction systems can compare available replacement carburettor options.

The chassis retained the distinctly European feel that helped separate the CR125 from contemporary Honda, Yamaha, Kawasaki and Suzuki machines. A 45 mm Marzocchi inverted fork was paired with a Sachs linkage rear shock, giving around 300 mm of front-wheel travel and 320 mm at the rear. Period riders often praised the bike's stability and suspension once correctly set up, although fork condition and oil height can make a major difference today. The MXOwners fork oil reference is useful when servicing older motocross forks whose previous setup is unknown.

Owners restoring a 2001 CR125 should also pay close attention to the usual age-related areas: linkage and wheel bearings, swingarm pivots, chain guides, air-filter sealing and the condition of the power-valve mechanism. Original parts can be harder to identify than on the more common Japanese machines, making the MXOwners Parts Finder useful when cross-checking replacement components.

The 2001 model represents Husqvarna during its Italian-built era, when the company was producing serious competition motorcycles with a character all their own. It was not a radical redesign, but rather a refined version of an established CR125 package. More than two decades later, a well-sorted example remains a light, fast and distinctive 125cc motocrosser that stands apart from the mainstream machinery of its period.
