Considering your height and the fact that you have never ridden a bike before, a suitable Royal Enfield motorcycle for you would be the Royal Enfield Classic 350 or the Royal Enfield Meteor 350. Both of these models are popular, comfortable, and relatively easy to handle for beginners. Here's a brief overview of each:
Royal Enfield Classic 350: The Classic 350 is an iconic model known for its vintage design and relaxed riding experience. It features a comfortable riding position, a torquey engine, and a classic styling that appeals to many riders. Its seat height is relatively low, making it accessible for riders with your height.
Royal Enfield Meteor 350: The Meteor 350 is a modern cruiser-style motorcycle that offers a smooth and refined riding experience. It has a comfortable riding position with forward-set footpegs and a wide handlebar. The seat height is also suitable for riders of your height.
Both the Classic 350 and Meteor 350 come with a manageable power output and have a friendly learning curve for new riders. They are equipped with features like electric start, disc brakes, and fuel injection for enhanced convenience and reliability.
It's highly recommended to visit a Royal Enfield dealership and take test rides of both models to see which one feels more comfortable and suits your preferences. Additionally, attending a motorcycle training course can help you gain confidence and develop essential riding skills before hitting the road.
