KTM 350 XC-F (2011-2012) Review: The Sweet Spot of Enduro Performance

Introduction

When KTM unleashed the 350 XC-F in 2011, it rewrote the rulebook for enduro motorcycles. Positioned between the fiery 250cc and burly 450cc machines, this Austrian-engineered bike promised a "Goldilocks" balance of power and agility. After spending days thrashing this orange beast through rocky trails, muddy woods, and open fire roads, it's clear why this generation remains a benchmark for off-road enthusiasts. Let’s dissect what makes this 107.8 kg (237.7 lb) machine a legend.

Engine Performance: Precision Meets Versatility

At the heart of the 350 XC-F lies a 349.7cc liquid-cooled single-cylinder engine that feels like engineering sorcery. The 88mm bore and 57.5mm stroke (3.5 x 2.3 inches) create a high-revving character with surprising low-end torque. With a 13.2:1 compression ratio and Keihin fuel injection, the engine delivers crisp throttle response—no carbureted hiccups here.

Riding Impressions:
- Low RPM: Tractors up technical climbs like a 450 but without arm-wrenching torque
- Mid-Range: Where this engine sings. Perfect for overtaking on trails or maintaining momentum
- Top-End: Revs freely to 11,500 RPM, though you’ll rarely need to explore this range

The 6-speed gearbox is a revelation. The ratios are spaced tighter than a Swiss watch, letting you claw out of mud pits in second gear or cruise at 90 km/h (56 mph) on connecting roads. The hydraulically operated clutch requires just one finger to modulate—a godsend during 3-hour harescrambles.

Chassis and Handling: Agile Meets Unbreakable

KTM’s signature chrome-molybdenum steel frame strikes a perfect balance between flex and rigidity. Paired with a 1495mm (58.9") wheelbase and 375mm (14.8") ground clearance, the bike dances over roots and rocks while feeling planted at speed.

Key Handling Traits:
- Flickability: Changes direction like a trials bike—ideal for tight woods
- High-Speed Stability: No headshake even when charging through whoops at 70 km/h (43 mph)
- Weight Distribution: Feels 20kg lighter than its 108kg dry weight suggests

The CNC-machined triple clamps and Pro Taper handlebar provide laser-sharp steering feedback. You’ll find yourself taking inside lines you never thought possible.

Suspension: WP’s Masterclass

The 350 XC-F’s suspension setup is where KTM’s race heritage shines:

Front:
- WP Up Side Down 4860 MXMA CC forks
- 300mm (11.8") of travel
- Adjustable compression/rebound for everything from granite slabs to MX track landings

Rear:
- WP 5018 BAVP DCC shock
- 317mm (12.5") travel
- Progressive linkage maintains composure on big hits

Setup Tip: For technical enduro, reduce fork pressure by 5-7% from stock. The bike will reward you with plusher small-bump compliance.

Ergonomics: Built for War, Designed for Comfort

At 992mm (39.1"), the seat height intimidates shorter riders initially. But the narrow frame and sculpted seat let most riders dab a foot when needed. The 7.5L (1.98 gal) tank is perfect for 100-120km (62-75 mi) rides—though serious enduro warriors will still pack extra fuel.

Standing Comfort:
- Footpegs positioned for natural attack posture
- Handlebar bend reduces arm pump on long descents
- Grippy seat/tank interface for cornering confidence

Brakes and Wheels: Stopping Power, Austrian-Style

• Front Brake: 260mm disc with Brembo caliper – one-finger stoppies even in mud
• Rear Brake: 220mm disc – progressive enough for technical climbs
• Tire Setup:
• Front: 80/100-21 (predictable slide control)
• Rear: 100/90-19 (excellent bite on loose terrain)

Pro Tip: Swap to a trials tire for hard-packed conditions—transforms rear traction.
