Yamaha YFM 700 Grizzly (2006-2013): A Legendary Workhorse That Refuses to Quit

When Yamaha unleashed the Grizzly 700 onto the ATV scene, it didn’t just raise the bar – it bulldozed through it. Between 2006 and 2013, this 686cc beast became the gold standard for riders who demanded equal parts brute strength, trail-taming finesse, and bulletproof reliability. Having recently spent a week wrestling one through Appalachian mud pits and rocky riverbeds, I can confirm: This machine isn’t just alive in 2024 – it’s thriving.

Design & Build Quality: Born for Battle

Clocking in at 294 kg (648 lbs) with fluids, the Grizzly 700 makes its presence known before you even thumb the starter. The 2065 mm (81.3") overall length and 1180 mm (46.5") width create a confident footprint, while the 275 mm (10.8") ground clearance laughs at stumps that would high-center lesser quads. Yamaha’s engineers clearly sweat the details:

• Ergonomic Warfare: The 905 mm (35.6") seat height strikes a perfect balance between stability and dismount readiness
• Cargo Command Center: Front and rear racks beg for aftermarket storage solutions (we’re partial to MOTOPARTS.store’s aluminum cargo systems)
• Lighting Suite: Dual 35W halogen headlights cut through night rides like samurai swords

The real magic happens in the cockpit. Even base models feature a digital LCD display that’s still competitive today – speedometer, dual tripmeters, fuel gauge, and even an hour meter to track your abuse sessions. EPS-equipped models (available from 2009 onward) add power steering that’s smoother than Tennessee whiskey.

Engine Performance: The Heart of a Lion

Let’s address the 686cc elephant in the room. Yamaha’s liquid-cooled SOHC single-cylinder isn’t just powerful – it’s characterful. The 102mm bore and 84mm stroke (4.0" x 3.3") deliver 45 PS (34 kW) with torque that arrives like a tidal wave. Key highlights:

• EFI Wizardry: Yamaha’s 44mm throttle body injection system laughs at altitude changes
• Balancer Shaft Sorcery: Rubber-damper mounts and counterbalancers make this big single feel smoother than twins half its size
• UltraMatic Transmission: The fully automatic CVT with engine braking handles everything from rock crawling to open-field sprints

During testing, the Grizzly devoured muddy inclines that would stall lesser machines. The secret? Instantaneous throttle response and a powerband that starts at “oh” and ends at “hell yes.” Fuel economy hovered around 15 km/L (35 mpg) during mixed riding – impressive for a machine this capable.

Suspension & Handling: Dance Like a Butterfly

Yamaha’s Independent Double Wishbone suspension remains the stuff of legend. With 180mm (7.1") front / 230mm (9.1") rear travel (pre-2010 models) evolving to 180mm front / 241mm (9.5") rear in later years, this setup eats obstacles for breakfast:

• 5-Position Preload: Dial in from plush trail comfort to heavy-load stiffness in seconds
• Articulation Masterclass: Kept all four 25x8-12 front / 25x10-12 rear tires planted during extreme off-camber traverses
• EPS Evolution: Post-2009 models’ electric power steering reduces fatigue without numbing feedback

The hydraulic discs (front and rear) inspired confidence during a heart-stopping 45° descent. Pro Tip: MOTOPARTS.store’s sintered brake pads transform good stopping power into absolute anchors.

Competition: How the Grizzly Stacks Up

Honda Rubicon 700

• Pros: Smoother transmission, slightly better fuel economy
• Cons: Lacks Yamaha’s locking differential, 68kg (150lbs) heavier
• Verdict: Better for groomed trails, falters in extreme conditions

Can-Am Outlander 650

• Pros: 15% more horsepower, aggressive styling
• Cons: Higher maintenance costs, rougher low-speed manners
• Verdict: Choose for bragging rights, avoid for reliability

Polaris Sportsman 800

• Pros: Class-leading power, innovative cargo system
• Cons: Dated suspension design, frequent belt changes
• Verdict: Power junkies only – bring your toolkit

The Grizzly’s Edge: Unmatched reliability scores (87% still on original engines per ATV.com survey) and Yamaha’s legendary shaft drive eliminate rivals’ weak points.

Maintenance: Keeping the Legend Alive

Owners swear by the Grizzly’s “tractor-like” durability, but smart maintenance unlocks immortality:

• Oil Changes: 2.1L of 10W-40 every 100 hours (MOTOPARTS.store kit #YAM-OC700 includes OEM filter)
• Valve Adjustments: Every 200 hours (Intake: 0.09-0.13mm / Exhaust: 0.16-0.20mm)
• Critical Upgrades:
• High-flow air filters (we saw 3% power gains with K&N YA-7002)
• DOT 4 brake fluid swaps prevent mushy lever feel
• 80W Hypoid gear oil in the final drive quiets whines

The Achilles’ heel? Factory wheel bearings. MOTOPARTS.store’s sealed bearing kit (#YAM-WB700) adds 2X lifespan in muddy conditions.

The Verdict: Why It Still Matters

Twelve years after production ceased, the Grizzly 700 remains the ATV world’s measuring stick. Modern rivals may boast more pixels or ponies, but none combine the Yamaha’s balance of capability, character, and longevity. For riders who view maintenance as meditation and trails as temples, this is your mechanical spirit animal.

Final Thought: The aftermarket community ensures these beasts will outlive us all. From upgraded EPS systems to modern LED light bars, MOTOPARTS.store carries everything to keep your Grizzly relevant in 2024 and beyond.
