Does the RE Interceptor 650 has what it takes to rival against the Street Twin which is an entry-level offering from a premium motorcycle manufacturer like Triumph

Triumph has launched the new 2019 Street Twin in India recently. There is no doubt in the fact that the Street Twin is Triumph’s best selling retro bike because it outsells every other retro bike in their lineup. This is also the bike that people first buy and then customize according to their preference from the long list of accessories that Triumph offers as an optional extra.

The retro-styled motorcycle has been around since the year 2016 and every Triumph motorcycle fan knew a thing or two already about the motorcycle. Like every year Triumph has given some noticeable updates to their 2019 model to keep things fresh. The British two-wheeler manufacturer has worked hard to give the new Street twin more performance and better specification for the year 2019.

Today we are comparing the Triumph’s entry-level Street Twin with the flagship Royal Enfield offerings the Interceptor 650. Although the Street Twin costs more than double of what the Interceptor is worth still we have decided to compare the specs and figures of these two motorcycles side by side.

Royal Enfield Interceptor 650 Vs Triumph Street Twin Styling Comparison

The 2019 Street Twin is more like an enhancement of the existing model. The reason why this modern classic outsells every other premium modern Classics available in the market is because of the fact that it has simple ergonomics, it is easy and fun to ride and also has got simple styling. The 2019 Street Twin retains the same silhouette.

It gets round shaped headlamps towards the front which uses a brushed aluminium clamp to hold the headlamp in place. Triumph has also increased the height of the seats a little more and it now stands at 760 mm while it also gets some extra cushion as well (10 mm to be exact). Besides that the analog plus digital instrument cluster provides almost all the information to the rider.


To bring some fresh air of change Triumph has also tweaked its design logos on the fuel tank to make them appear different. There is also a new alloy wheel as well which gets polished spokes. The Street twin also provides a USB charger positioned under the seat.  The motorcycles weigh 198 kilograms (dry) and has a 12-liter fuel tank.

The Royal Enfield Interceptor 650 on the other hand also has a simple design. There are many signs of cost-cutting on the motorcycle. To begin with, it does not get a clear lens for its headlamp. The taillamp and side turn indicators all use conventional bulbs in place of LED indicators. The rest of the fit and finish quality looks impressive according to Royal Enfield standards.

The twin-pod instrument cluster is easy to read and provides some vital information. The styling of the motorcycle definitely looks retro. The overall fit and finish quality of the materials might not be at par with Triumph’s standard but they are quite impressive than the rest of the RE motorcycles out there. Just like Triumph, Royal Enfield also provides plenty of additional accessories with the Interceptor 650 as well.
