EICMA 2017: Royal Enfield 648 Twin Revealed


I’ve ridden and loved the newest iterations of Royal Enfield’s single-cylinder fashions, however none of them, not even the top-spec (29 horsepower) Continental GT café-racer, make sufficient energy to be comfy to experience in trendy, high-speed site visitors situations. Till now, at the least.

Let’s give a heat welcome to what could be the first actually all-new mill within the firm’s lengthy historical past, the 648cc parallel Twin. It’s not likely a shock – Royal Enfield has been open about wanting a bigger, extra highly effective bike for abroad markets, and I’ve even seen spy pictures of prototypes. Now the corporate has revealed element pictures and particulars.

It doesn’t seem like a lot, however trendy ancillaries in a Royal Enfield motor – stability shaft, overhead cam – can result in a clean, enjoyable driving expertise, particularly for entry-level riders.

The brand new mill drags the 62-year-old Indian firm kicking and screaming into the late 20th century. Designed by Royal Enfield’s Know-how Centre in Leicestershire, England, it’s a fairly customary piece of engineering that wouldn’t look misplaced in a 1970’s Japanese product, however it does have some trendy options.

So, our thought is to not dominate the market however to herald one thing which may be very totally different from what is accessible.” Youthful riders – and Lal instructed us RE is promoting to a whole lot of youthful, first-time consumers – need ease of use, reliability, character and worth. A manageable, worth priced 40-horsepower retro-Twin might do very nicely on our shores.
