2010 Husqvarna WR250
Husqvarna continues to believe in two-strokes.
The WR250 is the response Husqvarna took to the E2 Class with Barlosz Oblucki.
Its legendary, all conquering engine needs no introduction.
For 2010, improvements have been made to the exhaust system to provide smoother delivery and a better power curve. The biggest news however, is in the suspension department. New Kayaba 48 mm forks dominate the front of the bike and are fully adjustable for compression and rebound.
The high performance cartridge 28 mm piston is exactly the same as the one on the team racing bike. The new solution has also meant redesigning the steering clamps. The WR250 too now features IDP graphics.
WR250. For those who like their race bikes pure.
