The CR500AF is more than a motocross bike; it’s a testament to the enduring power and mystique of two-stroke engineering. To truly appreciate this legendary machine, it’s important to understand the history and evolution that led to its creation. In this first installment of our 7-part CR500AF blog series, we’ll explore the roots of the CR500, its journey through motocross history, and how it inspired one of the most sought-after two-stroke conversions in the world.

The Birth of the CR500

Introduced in 1984, the Honda CR500 quickly became an icon in the motocross world. Featuring the largest two-stroke engine Honda ever produced, this bike was designed to dominate tracks and desert races alike. Its raw, unfiltered power made it a favorite among riders seeking adrenaline-pumping performance.

What Made the CR500 Stand Out?

The original CR500 wasn’t just another dirt bike. It was a machine designed to push boundaries and break records:

  • Immense Power: The CR500’s two-stroke engine delivered unmatched acceleration and torque, making it the most powerful motocross bike of its time.
  • Mystique and Legacy: Riders were captivated by its combination of power and simplicity. Unlike modern bikes with complex electronics, the CR500 was all about raw mechanical force.
  • Racing Prowess: The CR500 excelled in challenging environments, earning its stripes in legendary events like Baja, Hatta, and Finke.

The End of an Era

Despite its immense popularity, the CR500’s production came to an end in 2001. As four-stroke engines began to dominate motocross, Honda shifted its focus, leaving the CR500 behind. The decision marked the end of an era for two-stroke enthusiasts.

Why Did Honda Stop Making the CR500?

The rise of four-stroke technology played a major role in the CR500’s demise:

  • Regulations: Stricter emissions standards made two-strokes harder to justify.
  • Market Shift: Four-strokes gained favor for their smoother power delivery and easier handling.
  • Competition: The demand for lighter, more efficient bikes led manufacturers to prioritize innovation over tradition.

While the CR500 faded from production lines, its legacy only grew stronger, fueled by its reputation as a machine that could conquer anything.

The CR500’s Legacy in Motocross

Even after production ceased, the CR500’s influence on motocross was undeniable. During its prime, it stood above its competitors, with only the Kawasaki KX500 coming close to matching its performance.

Why Riders Loved the CR500

  1. Unmatched Performance: The CR500 was known for its explosive power and ability to dominate both motocross tracks and desert races.
  2. Simplicity: With no complex electronics, the bike relied on pure mechanical ingenuity.
  3. Cultural Icon: Even today, the CR500 is revered by riders and collectors alike.

Modern Comparisons

While today’s 450cc four-strokes may boast more power on paper, they don’t evoke the same emotional response as the CR500. The visceral thrill of riding a two-stroke beast remains unmatched, making the CR500 a legend in its own right.

The Rise of the CR500AF

As motocross technology advanced, enthusiasts began searching for ways to keep the CR500 engine alive. This desire gave birth to the CR500AF conversion, which pairs the iconic two-stroke engine with a modern aluminum twin-spar chassis.

What Sparked the Conversion Movement?

The introduction of aluminum frames in 1997 revolutionized motocross. Lighter, stronger, and more durable, these frames offered significant handling improvements. Riders wanted to combine the raw power of the CR500 engine with the advanced ergonomics of modern bikes, leading to the first CR500AF conversions.

Challenges of Early Conversions

The early days of CR500AF conversions weren’t easy. Builders faced significant challenges, including:

  • Frame Modifications: Early conversions required extensive adjustments to the frame rails to fit the engine securely.
  • Compatibility Issues: Aligning the engine mounts with modern chassis designs was a complex and time-consuming process.
  • Lack of Standardization: Without established conversion kits, every build was a custom job, requiring precision and ingenuity.

Despite these challenges, the CR500AF quickly gained popularity as riders embraced the opportunity to modernize their beloved two-strokes.

Evolution of the CR500AF Conversion Process

Over time, the CR500AF conversion process has become more streamlined, thanks to advancements in chassis design and engineering techniques. Today’s conversions benefit from:

  • Refined Frame Designs: Modern frames are better suited for two-stroke conversions, reducing the need for extensive modifications.
  • Custom Components: Machined engine mounts and carbon airboxes ensure seamless integration and improved performance.
  • Expert Workshops: Specialized builders like Garage Eleven have perfected the conversion process, delivering bikes that perform as well as they look.

Why the CR500AF Remains Popular
