Major updates for 2021 Triumph Bonneville line-up

2021 Triumph Bonneville range

Triumph have undertaken a major revision of the entire Bonneville line-up with engine updates to help meet Euro5 emissions legislation and up to a 20 per cent power boost thrown in to the bargain!

It is the 900cc T100 and Street Twin variants that get that big performance increase with power jumping from 54 to 64 horsepower.  That peak power arrives at 7400 rpm, 1500 rpm higher, while the unchanged torque figure of 80 Nm peaks at 3750 rpm, 550 rpm higher than before.  80 per cent of the peak torque is available from as low as 2000 rpm. 

The red-line is increased by 500 rpm in what should prove a much more willing performer than before, with lower inertia throughout the engine with a lighter crank and balancer shafts. Helping save weight is a thinner clutch cover and new magnesium cam cover. 

The improvements don’t stop there with new cartridge forks and a higher specification Brembo brake for the T100 models. The T100 is also 4 kg lighter than before and now has riding modes. 

Street Twin gets a more comfortable bench seat, new cast rims, bodywork and a host of tweaks that improve the finish throughout the machine.

Joining the range is a new Limited Edition Gold Line Street Twin of which only 1000 will be produced. The Gold Line edition features extra bespoke detailing measures that help the machine stand out from the crowd. 

The bigger engined T120 machines are now 7 kg lighter and also score higher spec’ braking hardware from Brembo. The 41 mm forks get new cartridge internals. 

The rims are now much lighter and the instruments have been updated. Cruise control is now standard and enhanced new riding modes improve the package further. 

The 1200 engined machines have not gained any boosts to their peak outputs in the transition to Euro5 with horsepower still rated at 79 horsepower at 6550 rpm while the 105 Nm of peak torque is now delivered at 3500 rpm, 400 rpm higher than their predecessors. 

The handsome laid-back Speedmaster scores new 47 mm Showa cartridge forks. A different tune compared to the T120 sees the Speedmaster make a little more torque at the expense of a couple of ponies. 106 Nm at 3850 rpm is the peak number, 90 per cent of which is sustained through to 5750 rpm while its 77 horsepower peak arrives at 6100 rpm. 

The Bobber boasts almost identical dyno numbers to the Speedmaster.  A bigger 12-litre fuel tank has been added to the Bobber, three-litres more than before, and is also suspended by 47 mm Showa cartridge forks but rides on a single rear shock, compared to the twin RSU rear ends seen on most of the 2021 Bonneville range. 

All machines feature 16,000 km service intervals and are expected to start arriving in Australia from the second quarter of 2021.
