The switchover from BS-III emission norms to BS-IV has left quite a few auto makers in a tizzy. Even after getting a full year to put their BS-IV bikes into show-rooms, it was a mad scramble for most makers a couple of days before the 1st April, 2017, limit to clear their old BS-III stock by offering massive discounts. Some, however, managed to get things in order, with Royal Enfield (RE) being one of them thanks to its comparatively low monthly production and exceptionally high demand. Royal Enfield did not make any big statement, but had already changed its portfolio to BS-IV. To meet the harsher emission norms, its latest model, the Himalayan adventure tourer, which was launched first 2016, was the latest to change to an electronic fuel-injection (EFI) setup from the carbureted form. There were a lot of talks throughout last year about an EFI version of the Himalayan on the horizon, and it seems this emission norms’ implementation was the perfect opportunity to make it happen.
With the addition of EFI though, there was no alteration to the engine’s specifications, with the 411-cc single cylinder, oil and air cooled unit putting out the same 24.5 hp at 6,500 rpm and a highest torque of 32 Nm at 4,250 rpm. The five-speed gearbox too stays unchanged. While there was no official word after the inclusion of EFI, the Himalayan’s price has been improved. Meanwhile, the 535cc engine of the Classic 500 and Continental GT series and the Thunderbird 500 were already running on fuel injection. But the same 500cc motor from the latter two bikes was carbureted in the Standard 500. Now, even that has switched to EFI to obey with the BS-IV norms. However, the company managed to make all its 350cc bikes compliant with BS-IV while still keeping them carbureted. These include the Thunderbird 350, Classic 350 series and the Standard 350.
