An 18 percent increase in peak power is a significant jump for the T100. The new motor revs an extra 500 rpm higher too. (Tim Keeton Impact Images/)
As you’d expect, the parallel twin conforms to tight Euro 5 regulations, and service intervals are every 10,000 miles, reducing the cost of ownership to the customer. (Tim Keeton Impact Images/)
The 59 pound-feet of torque (the same as before) is now delivered at 3,750 rpm, 500 rpm higher, with 80 percent of the peak torque available from as little as 2,000 rpm to 7,000 rpm (Tim Keeton Impact Images/)
For 2021 Triumph have dropped the T100’s weight by 8.8 pounds, and most of that saving has come via the new engine. (Tim Keeton Impact Images/)
New Brembo caliper gripping the single disc, a significant upgrade from the old Nissin stoppers. Weight has been reduced, and brakes have improved in spec, therefore stopping has improved from the old bike. Nissin still activates the rear stopper. (Tim Keeton Impact Images/)
ABS can’t be deactivated and isn’t lean sensitive. TC can be switched off at a standstill. (Tim Keeton Impact Images/)
There is no IMU fitted to the Bonnie, which means lean angle is not taken into consideration—the rider aids are simply measuring wheel speed plus other sensors for gear and throttle position. (Tim Keeton Impact Images/)
I love all the retro detailing around the bike: the original-looking pipes, the twist-turn fuel cap, the original-looking “carbs,” even the embossed Triumph logo on the bars, and brace across the front mudguard. (Tim Keeton Impact Images/)
This is a 2021 Bonneville, with modern fuel injection and rider aids, but it could easily be mistaken for an original—with a squint. (Tim Keeton Impact Images/)
With so many accessories you can really make the T100 your own, but you could quickly end up spending the family holiday money in the process. (Tim Keeton Impact Images/)
Triumph essentially offers two models: the Bonneville T120 1,200cc, and the bike we have on test, the “entry-level” T100, a 900cc parallel twin with a slightly lower spec than the T120 but priced more affordably. (Tim Keeton Impact Images/)
Despite the engineering challenges, the exhaust has a lovely flowing look to it. It’s just a shame it’s a little soulless. (Tim Keeton Impact Images/)
The fork and twin shocks lack any damping adjustment, and there’s only preload on the rear. (Tim Keeton Impact Images/)
