Overview

Introducing the 2009 CH Racing CH 511 Racing Big Wheels, a spirited minibike-cross motorcycle designed to ignite the passion of young riders aged 8 to 12. With its compact frame and robust features, this model stands out in the market as an excellent entry-level bike that merges fun with functionality. Crafted to conquer both dirt tracks and backyard trails, the CH 511 is all about building confidence and skills for budding motocross enthusiasts. Its lightweight build and nimble handling make it an ideal companion for those eager to explore the world of off-road riding. At the heart of the CH 511 lies a peppy 49.70cc single-cylinder, two-stroke engine capable of delivering 8 horsepower. This combination ensures a lively performance that encourages young riders to push their limits while still providing a safe and manageable ride. The air-cooled engine, paired with a DELL’ORTO PHBG 14 MS carburetor, offers responsive throttle control, making it easy for novice riders to learn the ropes of mastering a motorcycle. The telescopic front fork and a single shock absorber in the rear provide a smooth ride over rough terrains, ensuring that riders can tackle jumps and bumps with confidence. The CH 511 is packed with features that enhance both performance and safety. Its sturdy steel frame is designed to withstand the rigors of off-road riding, while the 175 mm front disc brake and rear drum brake work together to provide reliable stopping power. With a modest weight of 40 kg (88.2 lbs) and a seat height of 735 mm (28.9 inches), it is perfectly scaled for younger riders, allowing them to plant their feet firmly on the ground for added stability. Moreover, the bike’s generous ground clearance of 280 mm (11 inches) ensures that it can gracefully navigate various obstacles without bottoming out. **

Pros

  • Lightweight and Maneuverable: Weighing just 40 kg, it offers excellent agility, making it easy for young riders to handle.
  • Powerful Engine for Its Class: The 8 HP engine provides ample power for thrilling rides while remaining manageable for beginners.
  • Sturdy Build: The robust steel frame and quality suspension components ensure durability, allowing the bike to endure rough terrains and riding conditions.

Cons

  • Limited Fuel Capacity: With only 2.80 litres (0.74 gallons), fuel range may limit longer rides without frequent refueling.
  • Kick Starter Only: The absence of an electric starter might pose a challenge for younger or less experienced riders.
  • Targeted Age Group: Designed specifically for children ages 8 to 12, it may quickly outgrow its intended audience, limiting its longevity for riders as they grow.
