Triumph Street Twin review, road test

The electronically controlled single throttle body has also allowed for the engineers to extract more fuel efficiency from the motor – some 36 percent more than the old Bonnie, letting the Street Twin have the same tank range even with a smaller fuel tank.As per our highway tests, the bike dished out a mileage figure of 24.9kpl, which combined with the 12-litre fuel tank will make for a range of nearly 300km, before it runs out of petrol.
