Triumph Bonneville T120 (MY2025) vs Speed Twin 1200 (DD50-RS)
Triumph Bonneville T120 vs Speed Twin 1200: which one to buy once you're past the looks.
Turn into a fast bend on the Triumph Bonneville T120 and you're carrying a sixties British silhouette, its deep paint and clean instruments catching the light. The Triumph Speed Twin 1200 folds you down over its lower bars, feet tucked back on rearset pegs. It stays on its line while you're adding lean.
So which one do you buy?
The Speed Twin 1200 has the edge if…
Daily commuting & city riding

What makes each one tick
Bonneville T120
Low in the revs, the Bonneville's twin shoves the bike along on torque, and it doesn't ask you to chase the tach. With upright ergonomics and a 31.1 in (790 mm) seat, you're sitting tall with an easy reach to the pavement. The brake lever hauls real mass. The exhaust's note turns a grocery run into a ride.
Speed Twin 1200
On the Blue Ridge Parkway, the Speed Twin's Öhlins shocks and Marzocchi fork keep the chassis composed from one curve into the next. There's serious bite from the Brembo Stylema calipers when the next curve comes up. The throttle wakes a punchy twin. Its pull swells into a rush up top.

Known problems to check before you buy
Bonneville T120
No confirmed faults on file yet. That's not the same as fault-free.
Speed Twin 1200
- Rear turn signals too close to tail light (NHTSA Recall 25V-141) Recall 25V141000 Recall: Red rear turn indicators were installed too close to the rear tail/brake light, failing to meet FMVSS 108 separation requirements. This reduces other road users' ability to see the rider's intent, increasing crash risk. Dealers replace with amber signals free of charge.
