Sherco 450 SCF Factory [2019-2020]: A Test Ride Through Dirt and Grit
Introduction
When Sherco unleashed the 450 SCF Factory for the 2019-2020 model years, it wasn’t just another enduro bike—it was a statement. Designed for riders who demand precision in the unpredictable world of hard enduro and cross-country racing, this machine walks the tightrope between raw power and surgical control. After spending a day wrestling this French-engineered beast through rocky trails, muddy ruts, and steep hill climbs, I came away with a clear impression: this is a bike that rewards skill and punishes complacency. Let’s break down why the 450 SCF Factory remains a dark horse in the enduro arena.
Engine Performance: Carbureted Charm Meets Modern Muscle
At the heart of the Sherco 450 SCF Factory lies a 449.4cc liquid-cooled single-cylinder engine—a configuration that screams “no compromises.” The DOHC setup and 95mm bore deliver a thrilling powerband that’s more nuanced than you’d expect from a big thumper.
Key Observations:
- Carburetion Controversy: While competitors raced toward fuel injection, Sherco stuck with a carburetor (a Mikuni TMX 38, according to spec sheets). The result? A nostalgic, linear throttle response that feels alive under heavy load. It’s less “instant-on” than EFI bikes but offers a satisfying mechanical connection.
- Torque Curve Wizardry: The engine’s 63.4mm stroke gives it tractor-like grunt at 2,500 RPM, perfect for crawling over logs. But rev it past 6,500 RPM, and the character transforms into a snarling beast—ideal for open fire roads.
- Heat Management: Even during low-speed technical sections, the liquid cooling system kept temps stable. No boiling over, just a faint hum from the radiator fan when paused mid-trail.
Metric to Imperial Note:
- 449.4cc = 27.42 cubic inches
- Peak power (estimated): ~52 hp (38.8 kW) at 8,500 RPM
Chassis and Handling: Precision Tool or Brutal Taskmaster?
Sherco’s chrome-molybdenum steel frame is a work of art—stiff where it needs to be, forgiving where it counts. The 1,490mm (58.7") wheelbase strikes a balance between stability at speed and agility in tight turns.
Rider Ergonomics:
- Seat Height: At 950mm (37.4"), mounting requires commitment. Shorter riders might struggle, but the narrow seat profile helps when dabbing a foot.
- Ground Clearance: 355mm (14") means you’ll glide over obstacles that leave other bikes scraping skid plates.
- Weight Distribution: Despite its 112kg (247 lbs) dry weight, the Sherco feels lighter than its spec sheet suggests. The mass centralization is brilliant—pivot turns and wheelies come naturally.
Test Ride Highlight: On a steep, rocky descent, the bike’s balance let me shift my weight rearward without feeling like the front end would tuck. Confidence-inspiring? Absolutely.
Suspension and Brakes: KYB’s Finest Hour
Sherco’s partnership with KYB pays dividends here. The 450 SCF Factory’s suspension setup is a masterclass in off-road tuning.
Front Fork:
- KYB 48mm closed-cartridge forks (285mm travel)
- Adjustable compression/rebound; stiff enough for motocross jumps yet plush on root-infested trails
Rear Shock:
- KYB monoshock with 3-way adjustability (hydraulic preload, rebound, compression)
- Soaks up hard landings without bottoming out
Braking Performance:
- Front: Brembo 260mm rotor with 2-piston caliper—strong bite without being grabby
- Rear: 220mm disc (adequate for slide control)
Real-World Test: Blasting through a whoop section, the suspension maintained composure while the Brembos scrubbed speed predictably before sharp corners.
Competition: How the Sherco Stacks Up
The 450 SCF Factory entered a battlefield dominated by:
1. KTM 450 EXC-F: Lighter, fuel-injected, but with a harsher seat. Sherco counters with better low-RPM torque.
2. Husqvarna FE 450: Similar specs but pricier. Sherco’s KYB suspension outshines Husky’s WP XPLOR forks in technical terrain.
3. Beta 430 RR-S: Smoother power delivery but lacks Sherco’s top-end punch.
Sherco’s Edge: That carbureted engine—while old-school—simplifies field repairs. Perfect for riders who frequent remote areas without ECU diagnostics.
Maintenance: Keeping the Beast Alive
As a MOTOPARTS.store journalist, I’d be remiss not to highlight key upkeep needs:
- Air Filter Vigilance: With a carburetor, clean airflow is critical. Swap filters every 15-20 hours (or after dusty rides). Pro Tip: Our store stocks Twin Air filters pre-oiled for Sherco models.
- Oil Changes: Every 10-15 hours. Use 10W-50 synthetic (1.2L capacity).
- Chain Care: The O-ring chain needs regular cleaning. MOTOPARTS.store’s DID X-Ring chains are a durable upgrade.
- Valve Checks: Every 30 hours. Shim-under-bucket design requires patience but stays in spec longer than rivals.
- Suspension Service: Rebuild KYB forks annually. We offer OEM seals and Motul fork oil kits.
Common Upgrades:
- Skid plates (essential for rocky terrain)
- High-rise handlebars (improve standing posture)
- Sprocket kits (customize gearing for tighter trails)
Conclusion: A Contender for the Discerning Rider
The Sherco 450 SCF Factory isn’t for everyone—it demands skill and respect. But for those willing to master its quirks (yes, even the carburetor), it’s a machine that blends old-school charm with modern performance. Whether you’re racing hard enduro or exploring backcountry single-track, this bike will make you a better rider. And when it’s time to replace those worn brake pads or upgrade your footpegs, remember: MOTOPARTS.store has your back with Sherco-specific parts that keep the adventure alive.
