Kawasaki KLX 110 and Honda CRF 110 side-by-side pit bike comparison

Is a KLX 110 and CRF 110 a Pit Bike? Complete Classification Guide

"Yes, both the Kawasaki KLX110 and Honda CRF110 are classified as pit bikes. These Japanese-manufactured models represent the premium tier of the pit bike category, offering superior build quality, reliability, and extensive aftermarket support compared to budget alternatives.

Understanding Pit Bike Classification

Pit bikes are compact motorcycles originally designed for navigating pit areas at motocross racing events. Today, they've evolved into popular recreational machines characterized by several defining features:

  • Engine displacement: Typically 50cc to 160cc (some modified versions reach 190cc)
  • Frame size: Smaller, lightweight construction
  • Wheel dimensions: Generally 10-14 inch wheels
  • Seat height: Usually 26-29 inches
  • Primary use: Recreation, backyard riding, mini motocross racing, and learning

Why the KLX110 and CRF110 Are Pit Bikes?

Honda CRF110F Classification

The Honda CRF110F sits firmly in the pit bike category despite being manufactured by a major motorcycle company. Here's what makes it a pit bike: Engine Specifications:

  • 110cc air-cooled four-stroke engine
  • Approximately 7.5 horsepower output
  • Semi-automatic transmission (no clutch lever)
  • Fuel injection system (2019+ models)

Physical Dimensions:

  • Seat height: 26.8 inches
  • Wheelbase: Compact design for maneuverability
  • Weight: Approximately 165 pounds
  • 14-inch front wheel, 12-inch rear wheel

Intended Use: The CRF110 is marketed as a youth training bike and recreational pit bike, not a full-size off-road motorcycle. Honda positions it as an entry-level machine for younger riders and casual pit use.

Kawasaki KLX110R Classification

The Kawasaki KLX110R (and KLX110RL variant) is equally classified as a pit bike:

Engine Specifications:

  • 112cc air-cooled four-stroke engine
  • Four-speed transmission with automatic clutch (standard model)
  • Manual clutch option available (KLX110RL)
  • 18mm Keihin carburetor

Physical Dimensions:

  • Seat height: 26.8 inches (KLX110R), 28.7 inches (KLX110RL)
  • Weight: 167.5 pounds with full fuel tank
  • Suspension travel: 4.3 inches (standard), 5.5 inches front/5.2 inches rear (L model)

Market Position: Kawasaki explicitly markets the KLX110 as a pit bike and beginner-friendly off-road motorcycle. The company describes it as ""the ultimate pitbike for more experienced riders"" while remaining accessible to beginners.

What Sets These Models Apart from Other Pit Bikes

Premium Build Quality

Unlike budget Chinese pit bikes that often retail for $500-$1,200, the CRF110 and KLX110 command higher prices ($2,300-$2,600) due to:

  • Japanese engineering and quality control
  • More reliable components
  • Better long-term durability
  • Established dealer network support
  • Superior resale value

OEM vs. Aftermarket Origins

Most pit bikes available today are third-party models based on the Honda CRF50 design, manufactured in China with a perimeter frame chassis. The CRF110 and KLX110 are original equipment manufacturer (OEM) designs from respected motorcycle brands.

Extensive Modification Potential

Both models have thriving aftermarket communities. Popular modifications include: Performance Upgrades:

  • Big bore engine kits (140cc, 160cc, 190cc conversions)
  • Performance exhaust systems
  • High-flow air filters and carburetor upgrades
  • Manual clutch conversions (for auto-clutch models)

Handling Improvements:

  • Upgraded suspension (DNM, Elka, and other premium brands)
  • Longer fork legs for taller riders
  • Adjustable rear shocks
  • Performance brake upgrades

Rider Comfort:

  • Taller handlebars and extended cables
  • Extended shifter and brake pedals
  • Taller seat foam and covers
  • Wider footpegs

Pit Bike Racing and the 110 Class

Both the CRF110 and KLX110 are popular in organized pit bike racing:

  • Mini motocross events featuring dedicated 110cc classes
  • Supermoto pit bike racing on paved and mixed-surface tracks
  • Freestyle competitions where riders perform stunts and tricks
  • Backyard racing circuits at motocross facilities nationwide

Professional race series like Masters of Minis, 2-Up Minis, and regional championships all feature classes specifically for stock and modified 110cc pit bikes.

Are They Suitable for Adults?

While designed primarily for youth riders (ages 10-14), both models can accommodate adults with modifications:

Stock Configuration Challenges for Adults:

  • Low seat height makes knees uncomfortably high
  • Handlebar height too low for proper riding posture
  • Footpegs positioned for smaller riders
  • Limited suspension travel for heavier weights

Adult-Friendly Modifications:

  • Taller bars with extended cables (+$100-200)
  • Taller seat foam or complete seat replacement (+$50-150)
  • Suspension upgrades for heavier rider weight (+$300-800)
  • Extended shift lever and brake pedal (+$40-80)

Many adults successfully ride modified CRF110s and KLX110s for pit use, track day transportation, and recreational riding.

  • Lower seat heights: 26-30 inches
  • Lighter weight: 120-170 pounds
  • Four-stroke engines exclusively
  • Designed for recreational use and pit navigation
  • Not suitable for serious off-road terrain
  • More affordable: $500-$3,000

Full-Size Dirt Bikes:

Cost Considerations

Initial Purchase Price

Honda CRF110F: $2,500-$2,800 (2026 MSRP) Kawasaki KLX110R: $2,349-$2,549 (2026 MSRP) Both models represent a middle ground between budget pit bikes and entry-level full-size dirt bikes. Learn more about pricing factors in our pit bike cost breakdown.

Maintenance Costs

Lower ongoing expenses compared to dirt bikes:

  • Oil changes every 500-600 miles
  • Air filter cleaning/replacement more frequently in dusty conditions
  • Chain adjustment and lubrication every 2-3 rides
  • Valve adjustments are less frequent than in larger engines
  • Parts are generally more affordable than full-size bikes

Fuel injection advantage (CRF110): Modern CRF110 models with electronic fuel injection require less frequent tuning and perform better across varying temperatures and altitudes compared to the carbureted KLX110.

Modification Budget

Enthusiasts often spend $500-$2,000 on modifications:

  • Basic upgrades (bars, levers, pegs): $200-400
  • Mid-level performance (exhaust, sprockets): $400-800
  • Advanced mods (suspension, big bore kit): $1,000-2,500+

Street Legality: Can You Ride Them on Roads?

Standard Configuration: Neither the CRF110 nor the KLX110 comes street-legal from the factory. They lack the required equipment such as:

  • DOT-approved headlights and taillights
  • Turn signals
  • Mirrors
  • Horn
  • Street-legal tires

Making Them Road Legal: While challenging, some riders successfully register pit bikes for street use by adding required equipment and working with DMV regulations. Requirements vary significantly by state. For comprehensive information on the process, challenges, and legal requirements, read our guide on how to make a pit bike road legal.
