The Speed T4 recently joined Triumph’s lineup as a simpler and more affordable version of the Speed 400. We have recently been able to spend some time with the Speed T4 and put it through our instrumented testing procedure. Here are the fuel mileage figures of the Speed T4.
Triumph Speed T4 real world fuel efficiency
As per our usual procedure, we started by running the Triumph Speed T4 on the highway for just under 53km, after which it took 1.63 litres of fuel, thus achieving a 32.15kpl mileage figure.
Once that was done, we headed to the urban confines of South Mumbai, running the T4 for a little under 50km. After that, it took 1.29 litres of fuel, which meant it returned 38.86kpl.
Triumph Speed T4 fuel-economy analysis
Comparing the Speed T4’s mileage numbers to the Speed 400’s (City: 30.67kpl, Highway: 33.57kpl) reveals that it is a more fuel efficient machine of the two.
Triumph has given the T4 a heavier crank and the torque band is now accessed earlier in the rev range. This means that you don’t need to rev the motor out to access its performance and you can hold higher gears at lower rpms. Both these factors as well as the significant 9hp help the Speed T4 eke out better mileage than the full-fat Speed 400.
Autocar India’s fuel efficiency testing
Our fuel efficiency testing routine starts off by first brimming the tank and ensuring that the bike is running the manufacturer's recommended tyre pressures. The bike is then ridden on fixed city and highway routes, where we maintain pre-decided average speeds that best mimic real-world scenarios. 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.
