The 2002-2007 Honda CR250R marks the final chapter in Honda’s legendary two-stroke motocross lineage, representing the pinnacle of their 250cc two-stroke motocross development. These bikes are cherished for their modern technology, race-winning potential, and symbolic status as the last of Honda’s production two-stroke motocross bikes.

Here's an in-depth overview of the 2002-2007 Honda CR250R:

Overview and Historical Context:

By 2002, the motocross world had begun shifting toward four-stroke bikes, particularly following Yamaha's introduction of the groundbreaking YZ250F and YZ450F. Despite this shift, Honda committed significant resources to further refining its two-stroke CR250R. The 2002-2007 CR250R is recognized for its remarkable handling, advanced aluminum frame, and potent—but challenging—RC-style case-reed engine.

2007 was the final production year for Honda's two-stroke CR250R, marking the end of an era.

Engine and Performance:

• Engine Specifications:
• 249cc single-cylinder two-stroke
• Liquid-cooled, RC-style case-reed induction (introduced in 2002)
• 5-speed close-ratio gearbox
• Performance Traits:
• Aggressive, explosive powerband
• Notoriously strong mid-to-top-end performance, but less low-end torque compared to earlier models
• The RC-style case-reed induction design provided increased top-end power but made powerband tuning more challenging, demanding skillful throttle control
• Carburetion:
• Mikuni TMX carburetor (introduced in 2002), later refined over the years but consistently tricky to dial in perfectly

Chassis and Suspension:

• Frame:
• Third-generation twin-spar aluminum frame introduced in 2002; continually refined for optimized handling and reduced weight
• Recognized for improved flexibility and rider comfort compared to earlier aluminum frames (1997-2001)
• Suspension:
• Premium Showa inverted forks and Showa Pro-Link rear shock with fully adjustable compression and rebound damping
• Improved stock suspension performance, particularly notable in 2005-2007 models, making the bike competitive out-of-the-box
• Braking System:
• Powerful Nissin hydraulic disc brakes (front and rear), highly effective and reliable throughout these years

Evolution by Model Year (2002-2007):

2002-2004:

• Introduction of the RC case-reed induction system, offering strong, but somewhat peaky power.
• Riders noted the engine’s demanding power delivery, requiring careful carburetion tuning.
• Suspension and frame improvements significantly boosted handling and track feel.

2005-2007:

• Refined suspension, better fork action, and improved rear shock setup out-of-the-box.
• More balanced aluminum frame geometry improved rider comfort and cornering performance.
• Carburetion improvements made the bikes easier to tune compared to earlier RC-valve models, though still more finicky than traditional reed-valve engines.
• The 2007 model—highly desirable—represents the culmination of Honda’s two-stroke motocross engineering.

Racing Success and Legacy:

During this period, Honda’s factory race teams and privateers began transitioning heavily toward four-stroke machines, notably the CRF450R and CRF250R. Still, the CR250R remained a popular choice among two-stroke enthusiasts, amateur racers, and hardcore purists.

• Ricky Carmichael famously rode a CR250R to dominant victories early in the era (2002), marking one of the last great moments of two-stroke racing supremacy in AMA Supercross and Motocross.
• Honda’s shift to four-strokes signaled the decline of professional-level two-stroke racing, making these final CR250R models historically significant.

Collectability and Market Status:

Due to its status as Honda’s final two-stroke motocross bike, the 2002-2007 CR250R models hold significant collectible value, especially well-maintained, low-hour examples.

• Most collectible:
  2007 model (final production year), prized for historical significance and refined chassis.
• Good aftermarket parts availability, active enthusiast community, and continued vintage-class racing support keep these bikes highly desirable.

Common Issues & Maintenance:

• Carburetion & Jetting:
• The Mikuni TMX carburetor introduced in 2002 often required precise tuning to optimize performance and avoid a flat or bogging sensation.
• Power Valve (RC Valve) Maintenance:
• Regular cleaning is essential for maintaining optimal engine performance.
• Top-End Rebuilds:
• Recommended every 40-60 hours of use for peak performance.
• Suspension Seals & Bearings:
• Routine service of forks and linkage bearings is important to maintain handling quality.

Summary:

The 2002-2007 Honda CR250R represents both the height and end of Honda’s iconic two-stroke motocross lineage. Its distinctive RC-valve engine and refined aluminum frame set new standards in performance, even as the motocross landscape transitioned to four-stroke technology. These bikes remain highly coveted today as collectors' items and competitive platforms for two-stroke enthusiasts.
