Overview

Introducing the 2011 AJS Crazy Naked 50, a stylish and practical scooter that stands as a testament to the UK brand's commitment to delivering fun and functional urban transportation. With its minimalist design and approachable aesthetics, the Crazy Naked 50 is perfectly positioned for young riders, city commuters, and those looking to navigate tight urban spaces with ease. This motorcycle embodies the essence of freedom on two wheels, offering an accessible entry point into the world of motorcycling without sacrificing style or personality. At the heart of the Crazy Naked 50 lies a lively 40cc single-cylinder, two-stroke engine that delivers a spirited 3.49 horsepower at 7000 RPM. This powerplant, coupled with an automatic gearbox and a twist-and-go clutch, allows riders to effortlessly zip through city streets and reach a top speed of 48.3 km/h (30.0 mph). The compact dimensions and lightweight frame—tipping the scales at just 90 kg (198.4 pounds)—enhance agility and maneuverability, making it an ideal choice for those who seek an engaging ride without the intimidation of larger motorcycles. The air-cooled engine provides reliable performance, while the carburettor fuel system ensures that every twist of the throttle is met with an eager response. The Crazy Naked 50 is packed with features that cater to both novice and experienced riders. It boasts a comfortable seat height of 775 mm (30.5 inches), making it accessible for riders of various heights. With both electric and kick-start options, starting the bike is a breeze, while the 5-litre fuel capacity ensures plenty of range for urban adventures. The scooter is equipped with a single disc brake in the front for responsive stopping power and a drum brake in the rear for dependable performance. The telescopic front forks and single rear shock provide a smooth ride, absorbing bumps and imperfections in the road. With a warranty of 12 months for parts and labor, AJS stands behind their engineering, ensuring peace of mind for new owners. **

  • Lightweight and Agile: At only 90 kg, the Crazy Naked 50 is easy to handle, making it perfect for navigating tight city streets.
  • User-Friendly Features: With automatic transmission and a simple twist-and-go clutch, it's incredibly beginner-friendly.
  • Stylish Design: Its naked styling and sleek silver finish give it a modern and appealing look that attracts attention.

Cons
