Overview

Introducing the 2018 Royal Enfield Thunderbird X 350, a timeless classic that seamlessly blends vintage aesthetics with modern engineering. Positioned within the cruiser segment, this motorcycle appeals to riders who appreciate a laid-back riding experience without compromising on style. With its signature design and robust build, the Thunderbird X 350 is perfect for both urban commuting and long weekend rides, making it a versatile choice for enthusiasts and casual riders alike. Available in an array of eye-catching colors including Blue, Red, White, and Orange, this bike is as much about self-expression as it is about performance. At the heart of the Thunderbird X 350 lies a robust 346cc single-cylinder, four-stroke engine, delivering a commendable 19.8 horsepower at 5600 RPM. This power plant is engineered to provide a balanced torque of 28 Nm at 4000 RPM, ensuring that riders experience smooth acceleration and confident handling, whether navigating city streets or cruising along winding roads. The air-cooled engine, paired with a 5-speed gearbox, offers a top speed of 120 km/h (74.6 mph), allowing for spirited rides while maintaining a comfortable rev range. The motorcycle’s classic character is further enhanced by its compression ratio of 7.3:1 and a carburettor fuel system, which together deliver a timeless feel reminiscent of motorcycles from a bygone era. The Thunderbird X 350 doesn’t just excel in performance; it also comes equipped with features that enhance the riding experience. The bike's single downtube frame uses the engine as a stressed member, contributing to its lightweight yet sturdy construction, weighing in at 195 kg (429.9 lbs). The suspension setup, featuring telescopic front forks with hydraulic damping and a rear swingarm with gas shock absorbers, provides a comfortable ride over various terrains. Safety is not overlooked, with ventilated disc brakes at both the front (280 mm) and rear (240 mm), offering reliable stopping power. Additionally, the bike features both electric and kick-start options, catering to the preferences of traditionalists and modern riders alike. **
