Husqvarna WR 300 [2009-2010]: A Two-Stroke Enduro Legend Revisited
Introduction
The Husqvarna WR 300 arrived at a time when two-stroke enduro bikes were still kings of technical terrain, and this 2009-2010 iteration represents a fascinating blend of race-bred aggression and Scandinavian engineering. Born from Husqvarna's World Enduro Championship experience, specifically the machine campaigned by Seb Guillaume, this bike wasn't just another dirt bike - it was a statement. With its 293cc two-stroke heart, revised chassis, and competition-ready components, the WR 300 targeted riders who demanded razor-sharp response and durability in punishing conditions. Let's dissect why this machine remains a cult favorite among hardcore enduro enthusiasts.
Engine & Performance: The Angry Swede
At the core of the WR 300 lies its liquid-cooled 293.1cc two-stroke engine, featuring a square 72mm bore and stroke. But this isn't just any air-gulping two-stroke - it's a carefully tuned weapon.
Key Upgrades Over Previous Models:
- V-Force Reed Valve System: Improves throttle response across the RPM range
- Mikuni TMX 38 Carburetor: Larger than the WR 250's setup for improved fuel delivery
- Redesigned Exhaust Valve: Optimizes power curve for better low-end torque
- Revised Cylinder Head: Enhanges combustion efficiency
The power delivery is brutally effective - a characteristic two-stroke hit that comes alive above 5,000 RPM but surprises with tractable low-end grunt. Unlike modern fuel-injected four-strokes, the WR 300 demands active riding. Keep it singing in the meaty 6,000-9,000 RPM range, and it'll tractor up hillsides or blast through whoops with equal disdain.
Transmission Quirks:
The 5-speed gearbox (note: some sources incorrectly cite 6 speeds) has closely spaced ratios perfect for technical terrain. First gear is ultra-short - ideal for crawling over obstacles - while fifth becomes a desert-friendly overdrive. The wet multi-plate clutch requires a firm hand but offers excellent modulation during slippery climbs.
Real-World Riding Experience:
Starting requires commitment (kick-only, no electric assist here), but once alive, the engine barks through its redesigned expansion chamber with that classic two-stroke braap. On tight single-track, the WR 300 feels overqualified - its powerband almost too explosive for first-gear maneuvers. Yet open up the throttle on a fire road, and it transforms into a missile, the front wheel pawing at the air while the Sachs shock digests impacts with poise.
Handling & Suspension: Precision in the Rough
Chassis Setup:
- Frame: Steel single tube cradle with aluminum rear subframe (107kg dry weight)
- Front Suspension: 50mm Marzocchi USD forks (300mm travel) with compression/rebound adjustment
- Rear Suspension: Sachs shock with Soft Damp linkage (300mm travel), adjustable preload/compression/rebound
- Geometry: 27° rake, 100mm trail, 1495mm wheelbase
The WR 300's handling DNA is pure enduro - flickable yet stable at speed. The Marzocchi forks strike a balance between plush small-bump compliance and bottoming resistance, while the Sachs rear shock works harmoniously with the linkage to maintain traction. At 13.6 inches (345mm) of ground clearance, rocks and logs become suggestions rather than obstacles.
Braking Performance:
- Front: 260mm wave rotor with Brembo 2-piston caliper
- Rear: 220mm rotor with single-piston caliper
Stopping power is authoritative yet controllable - critical when descending rutted hillsides. The front brake offers superb feel, allowing precise modulation in loose terrain.
Ergonomics & Design: Function Over Fluff
Rider Triangle:
- Seat Height: ~37.4" (950mm) - tall but narrow for easy leg reach
- Footpegs: Serrated and positioned for aggressive standing
- Handlebar: Renthal Fatbar (standard bend) with minimal vibration
The WR 300 cossets taller riders but remains manageable for intermediates. Standing ergonomics are superb - the bike disappears beneath you during technical sections. The 2.5-gallon (9.5L) tank limits range but keeps weight centralized.
Notable Features:
- Digital dash with odometer/tripmeter/hourmeter
- LED-backlit headlight (surprisingly effective for night enduros)
- Minimalist bodywork that shrugs off crashes
Competition: How It Stacks Up
The WR 300's prime rivals in 2009-2010:
- KTM 300 XC-W
- Similar two-stroke power but with smoother delivery
- PDS rear suspension vs Husky's linkage system
-
6-speed transmission vs Husky's 5-speed
-
GasGas EC 300
- Softer power delivery better for technical trails
-
Lower seat height but heavier feel
-
Yamaha WR250F
- Four-stroke competitor with broader powerband
- 23kg heavier but easier for beginners
Husqvarna's Edge:
- Best-in-class suspension action for high-speed chop
- Most aggressive power delivery for expert riders
- Superior Brembo braking components
Maintenance: Keeping the Beast Alive
Critical Service Points:
1. Air Filter - Clean every 10-15 hours (use no-toil filters from MOTOPARTS.store)
2. Premix Ratio - Strict 50:1 with premium synthetic oil
3. Piston Replacement - Every 80-100 hours (watch for exhaust bridge wear)
4. Power Valve - Clean every 30 hours to prevent carbon buildup
5. Suspension Service - Rebuild forks/shock annually for plush performance
MOTOPARTS.store Upgrade Recommendations:
- FMF Gnarly Pipe: Improves low-end torque for technical riding
- Boyesen Supercooler Kit: Reduces engine temps by 15°C
- SXS Clutch Kit: Lighter pull with better engagement
- Pirelli Scorpion XC MidSoft Tires: Our favorite for mixed terrain
Conclusion: A Timeless Enduro Weapon
The 2009-2010 Husqvarna WR 300 remains a benchmark for pure two-stroke enduro performance. While newer bikes offer electric start and fuel injection, none replicate the visceral thrill of this Swedish berserker. It rewards skilled riders with unparalleled agility and punishes mistakes with a flick of its powerband - exactly how a proper enduro bike should. For those willing to embrace its temperamental nature, the WR 300 isn't just a motorcycle; it's a masterclass in analog off-road dominance.
