Yamaha YZ450F [2022] Review: A Motocross Weapon Refined

Introduction

The Yamaha YZ450F has long been a cornerstone of motocross performance, and the 2022 iteration continues this legacy with subtle refinements that elevate its track dominance. Designed for riders who demand precision, power, and reliability, this machine balances aggressive engineering with user-friendly features. Let’s dissect what makes this bike a standout in the 450cc class and why it remains a favorite among serious motocross enthusiasts.

Engine Performance: Controlled Fury

At the heart of the YZ450F lies a 449cc liquid-cooled, single-cylinder four-stroke engine featuring titanium valves and a 13:1 compression ratio. Yamaha’s focus on mass centralization is evident here—the backward-rotating crankshaft and compact cylinder head create a chassis-friendly power delivery that feels explosive yet manageable.

The Mikuni® fuel injection system (44mm throttle body) ensures crisp throttle response across the rev range. Low-end torque is plentiful, allowing riders to claw out of corners with authority, while the mid-range punch transitions seamlessly into a screaming top-end. The 5-speed gearbox is slick, though the ratios feel optimized for track use rather than trail versatility.

Key highlights:
- Electric starter for hassle-free restarts (a godsend during races)
- Launch control for perfect hole-shots
- Power Tuner app compatibility for fine-tuning fuel/ignition maps via smartphone

The engine’s character is best described as "predictably wild." It doesn’t intimidate like some European counterparts but rewards skilled riders with relentless acceleration. For amateur racers, the smooth power curve reduces arm pump; for pros, there’s enough grunt to clear rhythm sections with minimal run-up.

Chassis and Handling: Precision Meets Stability

Yamaha’s bilateral beam aluminum frame returns for 2022, offering a rigid yet lightweight foundation (112 kg / 245 lbs wet weight). Paired with the KYB® Speed-Sensitive System fork and fully adjustable rear shock, the YZ450F delivers a planted feel in corners and plushness over braking bumps.

Suspension specs:
- Front: 310 mm (12.2") wheel travel / 26.9° rake
- Rear: 318 mm (12.5") wheel travel

The Dunlop® Geomax MX33 tires (80/100-21 front, 120/80-19 rear) provide exceptional grip on hardpack and intermediate terrain. At 1.0 bar (14.5 psi) tire pressure, they absorb sharp edges without sacrificing sidewall support.

Standout handling traits:
- Neutral steering geometry inspires confidence in rutted turns
- Minimal chassis flex during hard landings
- Narrow profile enhances rider mobility

The 965 mm (38") seat height might challenge shorter riders, but the slim contact points make it easier to shift weight forward under acceleration or rearward for steep descents.

Features and Ergonomics: Modern Touches

Yamaha’s 2022 updates focus on usability. The two-tone motocross seat is firm yet grippy, locking the rider in place during aggressive maneuvers. Handlebars are positioned to accommodate both standing attacks and seated cornering, while the hydraulic clutch offers a light pull for all-day rideability.

Notable features:
- Launch control: Limits RPM during starts for optimal traction
- Smartphone connectivity: Adjust engine maps without aftermarket dongles
- Electric starter: Reliable even after crashes (no frantic kicking!)

The minimalist bodywork keeps weight low, though the Team Yamaha Blue aesthetics won’t win points for originality. Function over form reigns here.

Competition: How It Stacks Up

KTM 450 SX-F

KTM’s flagship boasts a sharper throttle response and slightly lighter feel (109 kg / 240 lbs). However, the YZ450F counters with superior mid-range torque and a more forgiving chassis. KTM’s WP suspension is plush but less adaptable to varied track conditions compared to Yamaha’s KYB setup.

Honda CRF450R

Honda’s offering shines with its nimble handling and aggressive styling. The CRF450R feels more agile in tight sections but lacks the YZ450F’s stability at high speeds. Yamaha’s Power Tuner app also provides a tuning edge over Honda’s more static ECU.

Kawasaki KX450

Kawasaki’s adjustable handlebar mounts and ergonomic tweaks cater to customization fans. However, the KX450’s engine lacks the Yamaha’s linear power delivery, often feeling abrupt in technical sections.

Verdict: The YZ450F strikes a balance between raw power and rideability, making it ideal for riders who value consistency over outright aggression.

Maintenance: Keeping the Beast Alive

Owners of the 2022 YZ450F will appreciate its straightforward maintenance regimen—critical for a bike that’s often pushed to its limits.

Oil Changes

• Capacity: 950 ml (0.95L / 1.0 US qt) with filter
• Recommended oil: 10W-30 or 20W-50 (API SG or higher)
• Frequency: Every 10-15 hours of hard riding

Pro tip: Use MOTOPARTS.store’s synthetic 10W-40 blend for extended durability in extreme temperatures.

Valve Adjustments

• Intake: 0.10–0.17 mm (0.004–0.007 in)
• Exhaust: 0.15–0.22 mm (0.006–0.009 in)
  Check every 20–30 hours. Yamaha’s titanium valves hold clearance well, but regular inspections prevent costly top-end rebuilds.

Brake Fluid and Coolant

• Brake fluid: DOT 4 (flush annually)
• Coolant: 1.0L (1.06 US qt) of ethylene glycol-based mix

Upgrade to MOTOPARTS.store’s high-performance brake pads for improved bite during muddy races.

Chain Care

The 520-size chain demands frequent lubrication and tension checks (35–45 mm slack). Consider a DID® ERT3 chain kit from MOTOPARTS.store for longer service life.
