2004 Husqvarna TC250 – Refining Husqvarna's New Four-Stroke 250

The 2004 Husqvarna TC250 was an evolutionary update rather than another clean-sheet redesign. The important leap had already occurred with the introduction of Husqvarna's compact 249.5cc DOHC four-stroke platform, and for 2004 the company concentrated on refining that package for motocross use. The short-stroke 76.0 x 55.0 mm engine retained its high 12.5:1 compression ratio, five-speed transmission and competition-focused character.

Fuel continued to be supplied by a 38 mm Mikuni TMR flat-slide carburettor fitted with an accelerator pump and throttle-position sensor. Correct jetting and accelerator-pump setup are important on surviving examples, particularly for clean starting and low-rpm response. Owners repairing an original unit can compare carburettor replacement options when worn components are difficult to source.

The chassis remained typically Husqvarna, using a steel single-beam frame, light-alloy rear subframe and 45 mm Marzocchi inverted fork with 300 mm of travel. A progressive-linkage rear shock provided 320 mm of wheel movement. The factory specified SAE 7.5 fork oil, and the MXOwners fork oil reference can help when servicing the original front suspension.

One notable feature for the period was electric starting combined with an automatic decompressor, unusual equipment on a serious motocross machine in this class. The TC250 also used a hydraulic clutch and dry-sump lubrication with twin oil pumps. Today, careful attention to oil condition, valve clearances, cam-chain wear and air-filter sealing is particularly important. The 2004 TC250 represents Husqvarna consolidating its new-generation 250 four-stroke platform before the model received further development in later seasons.
