2004 Husqvarna CR 250 – The Italian Two-Stroke Evolves

The 2004 Husqvarna CR 250 was primarily an evolutionary development of the previous year's motorcycle rather than a completely new generation. Built during Husqvarna's Italian period, it continued to offer riders a distinctive European alternative to the increasingly dominant Japanese 250 two-strokes and KTM's 250 SX.

Its 249.3 cc liquid-cooled two-stroke retained the familiar 66.4 x 72 mm bore and stroke, reed-valve induction and Husqvarna's H.T.S. exhaust power-valve system. A 38 mm Mikuni TMX carburettor supplied the mixture. On a surviving machine, worn carburettor components, incorrect jetting and deteriorated intake parts can seriously affect performance, so the MXOwners carburettor information and replacement options can be useful during restoration.

The CR 250 retained its European suspension combination, with a 45 mm Marzocchi upside-down fork providing around 300 mm of travel and a Sachs rear shock working through Husqvarna's progressive linkage. After two decades, suspension servicing and bearing inspection are particularly important. Owners rebuilding the chassis can use the motorcycle bearing finder when identifying replacement bearings.

Husqvarna specified premixed fuel for the CR 250, with a richer mixture during running-in and at least 2 percent oil after running-in. The MXOwners two-stroke premix calculator makes calculating the required oil quantity straightforward.

Today the 2004 CR 250 remains an uncommon motocross bike compared with contemporary Hondas, Yamahas and KTMs. A fresh top end, clean H.T.S. power valve, correctly jetted Mikuni, serviced suspension, fresh gearbox oil and properly maintained foam air filter are the key ingredients for returning one to good running condition. Properly sorted, it remains a fast and distinctive example of Husqvarna's Italian-built two-stroke era.
