2009 Husqvarna WR300

WR 300 – HUSQVARNA. The WR 300 started life as a transformation kit for the WR 250 but is now a fully-fledged member of the Husqvarna Enduro family to meet the demand for machines of this engine size.

As a perfect replica of the winning machine raced by Seb Guillaume in Class 3 of the Enduro World Championship series, the WR 300 always offers the rider progressive, useable power but, at the same time, is capable of superb performance when outright power alone is what counts.

The increase to 300 cc is thanks to an increase in the bore and the new piston now measures 72 mm (66.4 mm on the 250) to give 293.1 cc. Apart from the piston and bore, there is also a completely new exhaust valve and changes to the cylinder head and exhaust pipe in comparison with the 250 version.

The engine now features a V Force reed valve system and 38 mm TMX Mikuni carburettor. The WR 300 chassis components have been updated as all the other Enduro models: New disc brakes, newly calibrated forks and shock absorber and a new headlamp unit with compact digital display.

A new capacity variant for 2009, the WR300 is based on the well-proven two stroke WR250 and offers winning performance for the open class rider. The capacity increase comes from a larger cylinder bore but the changes don’t stop there. Husqvarna factory engineers have redesigned the cylinder head, power valve and exhaust system to match the increased capacity, which ensures the WR300 delivers strong power right through the rev range.

TWO-STROKE ENDURO MODELS

The new Husqvarna two-stroke Enduro models have seen significant modifications aimed at making these history making Enduro racers both lighter and even more competitive.
The WR 125 in particular has been nearly completely renewed with much of the frame design coming from its four-stroke siblings. The new WR 300 is a perfect replica of the machine ridden by Seb Guillaume in the World Championship series.

All 2009 models are fitted with newly calibrated Marzocchi forks and a new Sachs shock absorber. All the brake discs are “daisy” or Wave pattern to improve stopping regardless of surface conditions.
As for looks, the headlamp unit is slimmer and more aggressive and houses a new, more compact, lighter, digital display.
The graphics on the side panels are new as are the black anodised wheels. All the TE 2009 models feature a fuel injection system that was developed in collaboration with Mikuni. They have both electric and kick start systems fitted as standard. Let’s look at the details model by model.
