Husqvarna WR300 (2012)

Husqvarna WR300 (2012)

The new WR300 is the largest engine capacity 2-stroke in the Husqvarna range, yet it has a surprisingly linear and progressive power delivery. The engine is powerful, always ready and responsive to minimum throttle changes, but not so explosive as to be demanding to the point that only a pro can handle it. In fact it immediately became an alternative - light, manageable, and ? let's face it, money is a factor too - more economic, for E3 class pro bikers, or fans of extreme enduro. The engine is closely based on the crankcase of the WR250, which houses a larger bore cylinder (72 mm, giving an engine capacity of 293.1 cc). All component parts are top of the range: Ducati Energy digital ignition, Mikuni TMX38 carburettor and V-Force reed valve are just the more obvious examples. The five speed gearbox performs well across the range of power supplied by the engine.
One thing is sure: the Husqvarna CH Racing Team riders like to go against the grain. The WR300 is the bike of choice for Sebastien Guillaume. A choice that might seem daring, but the French champion surrounded by big, powerful 500 cc four-stroke machines - has for years
taken his place on the podium of the E3 class at the International Six Days Enduro Championship.
Because Guillaume likes his enduro tough, for real men, and that means the Husqvarna WR300, designed specially on the basis of his experience at the WEC. Indeed for a long time the Husqvarna "300" was simply a suped-up version of the WR250. When in 2008 it entered the Husqvarna price list as a model, the WR300 was immediately taken to heart by professionals and fans alike.

High-grade Ohlins spring elements designed for the hardest all-day Enduro racing are standard equipment – front and rear. Adjustability guarantees optimum tuning for the widest variety of terrains. A further highlight, the spring travel which at 10.8 inches (275 mm) front and 10.7 inches (272 mm) rear sets the trend for the Enduro ATV! The extremely durable chromoly steel A-arms can take the hardest professional cross country use. They have high-grade needle-roller bearings, are adjustable in camber and caster and can be easily exchanged. The rear axle is tapered, made of high-strength steel and allows for a variable rear width of 45 to 48.5 inches (1,076 to 1,148 mm).
With extremely powerful performance and perfect handling, the 525 XC is an offroad powerhouse on four wheels that is unrivaled in its class, bursting with energy, and very lightweight. A big reason why the 525 XC is a notch above every other ATV is its homologation for use on public roads, which not a lot of ATVs can boast of. Aside from lights and mirrors, the corresponding equipment includes a comfortable seat and a 13.4 liter long-range fuel tank to reduce the frequency of
breaks when out on tour.
Thanks to homologation for use on public roads, the 525 XC is the leader of the pack, not only off-road. Aside from lights and mirrors, the corresponding equipment includes a comfortable seat and a 13.4 l long-range fuel tank to reduce the frequency of breaks when out on tour.
One other unique detail about the 525 XC is a chassis that can be set for various types of use and different types of course. Camber and caster on the front axle are just as variable as the track on the rear. The shock absorbers have adjustable compression and rebound damping, as well as spring preload, which makes for an all-around versatile endure ATV that just speaks to the prospective owners everywhere.
