For a middle-aged mature rider with back pain problems, seeking a bike for comfortable cruising at a consistent speed of 75 km/h throughout the day, an important consideration would be a bike with an upright seating position and raised handlebars to minimize strain on the back. Additionally, a bike that performs well on potholes and bad roads would be advantageous.
The Royal Enfield Electra 350 could be a suitable option for such requirements. It features an upright seating position and raised handlebars, which promote a more comfortable riding posture and reduce strain on the back. The bike's suspension setup is designed to handle rough terrains and bad roads, providing a smoother ride.
Regarding vibrations, Royal Enfield motorcycles are known for having some vibration issues, particularly at higher speeds. However, the Electra 350 has been improved over the years, and the vibrations can be managed to an extent. Many riders find the vibrations to be acceptable, especially when the bike is ridden within its comfortable cruising range.
Ultimately, choosing the right bike depends on personal preferences and priorities. It is advisable to visit a local dealership, take a test ride, and assess the comfort and suitability of the bike for your specific needs. Additionally, considering other models with similar features, such as the Royal Enfield Classic 350 or other cruisers from different manufacturers, might help you make a well-informed decision.
