Euro5 engines, less weight on the T120 range, 10bhp power boost for T100 models
Next up for the 2021 updates merry-go-round is Triumph, with a solid overhaul for its Bonneville range of modern classics. The 1200cc T120 models – Bonneville and Bonneville Black, Bobber and Speedmaster – all get a revised Euro5 engine, a 7kg weight loss and a load of detail refinements.

Meanwhile, the smaller 900cc T100 models – the Street Twin and Bonneville T100 – get a new Euro5 engine tune with 10bhp more power and 4kg less mass, plus chassis and equipment upgrades.
Starting with the T120 models, the updated parallel twin engine gets a lighter crankshaft, plus tweaked balancer shaft and clutch assemblies that reduces inertia in the bottom end. Power remains the same at around 80bhp at 6,550rpm, while a retune of the top end cuts emissions below Euro5 levels.
The bigger story lies elsewhere though, with a 7kg weight saving overall. The Bonneville T120 now has lighter aluminium wheels, which claim to improve handling and agility, plus new Brembo twin-piston sliding calipers up front which boost stopping power. Away from the chassis, there’s now a cruise control setup as standard and new 3D-style clocks. The T120 Black adds a brown seat and a load of black-finished components: wheels, mirrors, exhaust and engine covers.
The Bobber custom has the new T120 engine, with the Euro5 retune, making peak power of 77bhp@6,100rpm, alongside a new larger 12 litre fuel tank (up from 9 litres), that claims to increase range by 33 per cent over the old bike. There are new wheels and front forks, with a chunky 16” front rim and 47mm stanchions giving an aggressive look, an updated dash and the same new Brembo brakes as the Bonneville.
Finally on the T120 range, the Speedmaster cruiser has the Euro5 engine with 77bhp, a new 47mm cartridge front fork and revised seat design for even more comfort.
Turning to the smaller 900cc T100 series, the parallel twin engine is overhauled for Euro5 compliance, and also makes 10bhp more power – a hefty uplift in grunt for the Bonneville T100 and Street Twin – to 64bhp@7,400rpm. There’s not a lot of detail on the engine mods, but Triumph says it revs 500rpm higher, and has a new lighter crankshaft, balancer shafts and magnesium engine covers. Those mods also contributes to a 4kg weight loss on the new models.
On the Bonneville T100, there are new Brembo brakes, plus a higher-spec cartridge front fork, 32-spoke classic wheels and a new dashboard layout.
The entry-level Street Twin roadster gets all of the above engine mods, adds a new, more comfy seat, and updated bodywork. There’s also a limited edition (to 1000 units) Gold Line edition of the Street Twin, with comes with hand-painted gold coachlines, gold pinstriped wheels and custom painted side panels.
There’s no final word on price or availability for the new modern classics range as yet – more as we get it.
