The 2021 Triumph Bonneville Bobber is a model-year-specific motorcycle, so current Triumph specifications and accessory listings should not be assumed to describe every 2021 bike. For exact specifications, service requirements and parts fitment, check the handbook for the motorcycle’s market or confirm its VIN with a Triumph dealer.
What is established about the 2021 Bonneville Bobber?
The available official material confirms the Bonneville Bobber family’s basic configuration, but it does not conclusively establish a complete specification for every 2021 market or variant. Triumph’s current US model page describes a 1200 cc liquid-cooled parallel twin, six-speed gearbox and chain final drive. Those are current-page details, not verified 2021 specifications.
A Spanish-language Triumph result titled for the 2021 Bonneville Bobber reports a 1200 cc engine, chain final drive, 16-inch wheels, a 12-litre tank, 251 kg wet weight and a 16,000 km/12-month service interval. The page context does not establish that these figures are specific to the 2021 model, so they should not be treated as definitive historical specifications.
Why do published specifications differ?
Triumph’s current US page lists a 3.7 US-gallon tank, 551.2 lb wet weight and servicing every 10,000 miles or 12 months. The Spanish result instead reports a 12-litre tank, 251 kg wet weight and a 16,000 km/12-month interval. These differences may reflect market or model-year variations, or changes in the pages themselves; the available material does not resolve the conflict.

The current US page also describes an 8-valve SOHC 1200 cc 270-degree parallel twin with maximum power of 77 HP at 6,100 rpm and maximum torque of 106 Nm at 4,000 rpm. It lists electronic fuel injection, a slip-and-assist clutch, 16-inch spoked wheels, 47 mm Showa front forks, monoshock rear suspension, twin 310 mm front discs and a 255 mm rear disc. These are current model-family specifications, not a verified 2021 specification sheet.
How to confirm the right service information
Do not apply the current online service interval or maintenance details to a 2021 motorcycle without checking the documentation for that bike. Use the owner’s handbook for its market and model year, or ask a Triumph dealer to confirm requirements using the VIN. This is especially important when specifications from different regional pages conflict.

The current Triumph specification identifies a chain final drive, making chain lubricant a relevant general consumable. It does not establish a lubricant brand or grade, cleaning product, chain slack measurement or maintenance cadence for a 2021 bike. Follow the applicable handbook for those details rather than inferring them from a current model page.

- 👍 Material: ✔ Stylish bars are constructed of 22mm OD (outer diameter) heavy-duty mild steel tubing that’s powder coated black for a sleek finish which remains durable after prolonged use and protects against corrosion caused by the elements and keeps them looking great.
- 👍Function: When a motorcycle falls, the bumper first comes into contact with the road, and then the bumper deforms under the effect of force to consume the kinetic energy of the motorcycle, which acts as a buffer to protect the motorcycle and reduce damage to the vehicle body.
- 👍Feature: At the same time, due to the lateral support of the bumper, the bumper and the exhaust pipe land first when the motorcycle falls to the ground, creating a safe space for the driver, especially the protection of the legs when the motorcycle falls. A motorcycle without a bumper will be pressed to the leg when it falls. Even if it is not hurt, the temperature of the engine and the muffler is very high and it is easy to burn.
- 👍 Easy installation: No drilling cutting welding other modifications are necessary for fitment—just simple hand tools and a desire to protect your motorcycle and who doesn’t have that? Keep your bike safe with a set of crash bar from the protection experts at Fayedenicy!
