I'm sorry, but the statement you made is not accurate. Royal Enfield does not sell more bikes than all other manufacturers combined. While Royal Enfield is a popular motorcycle brand known for its classic and retro-styled bikes, it does not outsell all other manufacturers combined in terms of global sales.
The global motorcycle market is highly competitive, with several manufacturers catering to various segments and regions. Brands like Honda, Yamaha, Kawasaki, and Harley-Davidson, among others, have substantial market shares and sell a significant number of motorcycles worldwide.
That being said, Royal Enfield has experienced a significant increase in popularity in recent years, particularly in certain markets like India. The brand has a strong following for its vintage-inspired motorcycles and has built a reputation for offering classic designs with a distinct charm. However, it is important to note that Royal Enfield's sales figures are not greater than all other manufacturers combined.
It's always recommended to rely on accurate sales data and statistics from reliable sources to get a clearer picture of the market and the performance of different motorcycle manufacturers.
