Overview
The Triumph Bonneville Speedmaster is a cruiser produced from 2018 to 2026. For 2026, its naturally aspirated, liquid-cooled 1,200 cm³ parallel-twin four-stroke makes 77 hp (58 kW) and 106 Nm at 4,000 rpm; wet weight is 265 kg.
The 705 mm seat height gives the bike a low seating position, while its 265 kg wet weight can make slow-speed maneuvering more demanding. The engine’s peak torque arrives at 4,000 rpm, and the slip-and-assist clutch can ease clutch effort and help calm the rear wheel on hard downshifts. ABS supports braking, and the 2026 fuel tank holds 14 L, up from 12 L in 2025.

Pros and cons
Advantages
Low seat
At 705 mm, the seat height can make it easier to get both feet down at a stop.
Strong low-rev torque
The 106 Nm peak at 4,000 rpm gives the engine useful pulling force without needing high revs.
ABS and slip-assist clutch
ABS adds braking support, while the slip-and-assist clutch can reduce lever effort and help steady the rear wheel during hard downshifts.
Things to consider
Heavy at walking pace
Its 265 kg wet weight can take more effort to balance and maneuver at low speeds.
Limited ground clearance
The 91 mm ground clearance leaves little room for uneven surfaces or tall obstacles.
Chain final drive
The chain needs cleaning and adjustment as part of routine maintenance.
