The Royal Enfield Thunderbird 350, equipped with a carburetor engine, is a cruiser-style motorcycle that is well-suited for normal city rides and occasional long rides on highways. The carbureted engine offers a classic riding experience with a noticeable amount of torque at lower RPMs, which is beneficial for city riding and low-speed maneuvering.
When it comes to highway riding, the Thunderbird 350 with a carburetor engine can comfortably cruise at moderate speeds, typically between 80-100 km/h (50-62 mph). It may be capable of reaching higher speeds, but it's important to note that sustained high-speed riding for long periods can put additional stress on the engine, potentially affecting its overall performance and fuel efficiency.
In terms of long-distance rides, the Thunderbird 350 with a carburetor engine can handle distances over 400 kilometers (approximately 250 miles) without significant issues, provided that the motorcycle is properly maintained and serviced. Also, ensure that you have sufficient fuel stops along your route, as carbureted engines tend to have slightly lower fuel efficiency compared to fuel-injected engines.
Overall, the Royal Enfield Thunderbird 350 with a carburetor engine can provide a reasonably comfortable and reliable riding experience for both city rides and occasional long rides on highways. However, as with any motorcycle, it's essential to perform regular maintenance, adhere to recommended service intervals, and ride responsibly to ensure the longevity and optimal performance of the bike.
