Follow usTriumph’s Speed T4 and Royal Enfield Hunter 350 are two of the most accessible retro roadsters you can buy from their respective manufacturers. While they differ in performance and character, both are aimed at riders looking for style, approachability and decent everyday usability. We've put both bikes through our real-world city and highway efficiency tests to find out which one sips fuel more efficiently.
Despite the sizeable difference in performance and output, the Speed T4 performs better in city conditions with respectable figure of 32.15kpl. Meanwhile out on the highway the T4 manages to impress yet again with a fuel efficiency figure of 38.86kpl. Combined we get an average figure of 35.50kpl which is quite close to its rival.
On the open road, the Hunter 350 manages to return marginally better highway economy with a figure of 39.80kpl. However, it gave us a slightly lower 30.60kpl fuel efficiency figure in the city. Combine the two and we get a close average of 35.20kpl.
Both the Triumph Speed T4 and Royal Enfield Hunter 350 deliver very similar results. The Speed T4 edges ahead in city conditions, while the Hunter returns slightly better numbers on the highway. Overall, the Triumph Speed T4 comes out on top by a narrow margin in average efficiency, while also offering better performance and refinement. However, if you prefer relaxed riding and the thump of a traditional single, the Hunter 350’s marginally better highway mileage could appeal to you. Either way, you won’t be refuelling too often with either of these bikes.

Where things start to diverge is when you consider the performance on offer. The Triumph Speed T4 is the more powerful motorcycle by a significant margin, making its efficiency figures all the more impressive. With 31hp and 36Nm, the T4 is a much sportier machine than the Hunter 350, which uses a simpler, long-stroke air-/oil-cooled engine producing 20.2hp. Despite this performance gap, the Triumph matches and even slightly exceeds the Hunter in efficiency, which speaks volumes about the modernity of its engine and fuel-injection system.
Our fuel-efficiency testing routine starts by first brimming the tank and ensuring the bike is running the manufacturer’s recommended tyre pressures. The bike is then ridden on fixed city and highway routes, where we maintain average speeds that best mimic real-world scenarios as well as keeping speed limits in mind. The payload on the bikes is kept constant by balancing rider weights and ballast, ensuring consistency across different vehicles and riders. At the end of the test cycle, the fuel tank is once again filled to the brim, giving us an accurate figure of how much fuel has been consumed against the trip meter reading.
