Honda CRF250X (2004-2017): The Enduro Workhorse That Refuses to Quit

Introduction: The Swiss Army Knife of Trail Riding

When Honda launched the CRF250X in 2004, they weren’t just releasing another dirt bike – they were creating a legend. This 249cc enduro machine bridged the gap between motocross aggression and trail-riding practicality, offering a "do-it-all" character that’s become increasingly rare in today’s hyper-specialized market. After spending a week with a well-maintained 2016 model, it’s clear why this motorcycle remained virtually unchanged for 13 years: Honda nailed the formula on the first try.

The Rider’s Perspective: Throw a Leg Over and Grin

Ergonomics & First Impressions

At 115 kg (254 lbs) wet weight, the CRF250X feels shockingly light when you first muscle it off the stand. The 958mm (37.7") seat height might intimidate shorter riders, but the narrow aluminum twin-spar frame lets you cheat downward. During my test ride through Rocky Mountain single-track, the bike disappeared beneath me during technical sections – a stark contrast to modern enduros that often feel like riding a filing cabinet.

Engine Character: Carbureted Charm

The liquid-cooled 249cc single bursts to life with either electric starter (a godsend after stall) or kick (redundancy matters 20 miles from pavement). Cold starts required 2-3 twists of the 37mm Keihin carb’s throttle – a ritual that’ll make EFI riders chuckle but connects you to the machine.

Power delivery is textbook Honda:
- 0-6,000 RPM: Tractors up hills at walking pace
- 6,000-9,000 RPM: Comes alive like a motocrosser
- 9,000+ RPM: 29.4 HP (21.4 kW) screams with intent

The 24.2 Nm (17.8 lb-ft) torque peak at 8,000 RPM feels deceptive – there’s more low-end grunt than specs suggest. Clutch modulation is butter-smooth, letting you finesse through switchbacks or loft the front wheel over logs.

Chassis & Suspension: Showa’s Masterclass

Front End Confidence

The 47mm inverted Showa fork (315mm/12.4" travel) handled everything from baby-head rocks to 3-foot drop-offs without bottoming. With 16-click compression/rebound adjustability, dialing in the setup took just 15 minutes of trail-side tweaking. Pro Tip: Start at 10 clicks out on compression if you’re between 68-82 kg (150-180 lbs).

Rear Suspension Sorcery

Honda’s Pro-Link rear shock serves up 312mm (12.3") of travel with separate low/high-speed compression adjusters. During a high-speed fire road blast, the rear tracked like a railcar despite washboard ruts. For technical climbs, the linkage ratio keeps the wheel planted when you need traction most.

Competition: How the CRF250X Stacks Up

Yamaha WR250F (2005-2015)

• Advantage: Wider powerband, 6-speed transmission
• CRF Edge: Lighter feel, superior low-RMP torque
• Upgrade Tip: Swap to WR250F’s 49T sprocket ($35) for faster trails

KTM 250 XC-W (2008-2016)

• Advantage: 2-stroke snap, hydraulic clutch
• CRF Edge: 40% longer valve service intervals, cheaper parts
• Upgrade Tip: Add KTM-style handguards ($75) for brush protection

Kawasaki KLX300R (2006-2020)

• Advantage: Electric start only, lower seat
• CRF Edge: 17% more suspension travel, 11 kg (24 lbs) lighter
• Upgrade Tip: KLX’s footpegs ($55) offer better grip when muddy

Maintenance: Keeping the Legend Alive

Valve Adjustments – Don’t Skip These

• Intake: 0.09-0.15mm (0.0035-0.0059")
• Exhaust: 0.25-0.31mm (0.0098-0.0122")
  Check every 40 engine hours – these Unicam® engines stay in spec longer than competitors when maintained properly.

Oil Changes Made Simple

• Engine Oil: 690ml SAE 10W-40 (with filter)
• Transmission: 670ml SAE 10W-40
  Pro Tip: Use JASO MA2 oil – the $2 premium prevents clutch slip.

Carburetor TLC

• Pilot Jet: #40 (stock) works up to 1,500m (4,921ft)
• Main Jet: #142 needs swapping above 2,000m (6,562ft)
• Fuel Screver: Start at 2.25 turns out

Chain & Sprocket Wisdom

The 14T/53T combo lasts about 80 hours. Upgrade to:
- Front: Steel 14T ($22)
- Rear: Aluminum 51T ($85) for faster trails
Always use a #520 O-ring chain – non-O-ring stretches 3x faster.

The Verdict: Timeless Trail Majesty

The CRF250X isn’t about cutting-edge tech – it’s about mechanical empathy. This bike reads your mind through footpegs and handlebars, converting rider input into trail poetry. While newer enduros boast fancy electronics, Honda’s decade-spanning design proves that reliability, tunability, and sheer rideability never go out of style.
