This is the maintenance schedule with associated service intervals for the Triumph Bonneville Bobber motorcycles, first released in 2016, and continuing through 2020.
Over the years, the Bonneville Bobber has evolved slightly, but not dramatically in a way that affects the maintenance. The maintenance for the Bonneville Bobber Black is identical — it’s just blacked out (and from 2021 only the Black is available, anyway), although the brakes are different.
The Bonneville Bobber is powered by a 1200cc liquid-cooled 8-valve 270-degree parallel twin that makes 57 kW (76 hp) @ 6,100 rpm, and 106 Nm @ 4,000 rpm. It drives its wheels through a six-speed gearbox and a final drive chain.
The maintenance for the Triumph Bonneville Bobber is very similar to other motorcycles with the 1200cc “High Torque” engine, even when they’re in a different state of tune, like in the Triumph Speed Twin.
What you need to service the Triumph Bonneville Bobber & Bobber Black
If you’re servicing your Triumph Bonneville Bobber or Bobber Blac, you need the below parts/consumables.
Most of them are common with the rest of the 1200cc High Torque range, but some are different (like the brake pads).
|Triumph||Part spec (Triumph Bonneville Bobber and Bobber Black)|
|Oil||Triumph recommends 10W/40 or 10W/50 semi or fully synthetic motorcycle engine oil that meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries.|
|Oil filter||Replace the oil filter every time you change the oil. Use Triumph part number T1218001. You can also use Hiflofiltro’s HF204RC (better than K&N these days).|
|Brake fluid||Triumph Bonneville Bobber motorcycles need DOT 4 brake fluid (they have a clutch cable, so you don’t need fluid for the clutch).|
|Coolant||Triumph uses Hybrid Organic Acid Technology coolant with a 50% ethylene glycol mix. Zerex G05 is a HOAT coolant that meets this spec.|
|Front brake pads||A popular upgrade is EBC brake pads for better bite, less fade, and longer life. The part codes are:|
– Triumph Bonneville Bobber 1200: FA142HH
– Triumph Bonneville Bobber Black: FA181HH (Brembo brakes up front)
|Rear brake pads||Use FA140HH for the rear pads on the Bobber or Bobber Black (same rear brake)|
|Spark plugs||NGK code LMAR8A-9. Note they’re sold individually. Make sure they’re gapped to 0.9mm with an appropriate spark plug gap tool.|
|Air filter||The Bonneville Bobber has two air filters, on the left and right. Part numbers are T2206530 and T2206531. A popular customisation is the K&N universal clamp-on filter (removing the airbox)|
|Cable maintenance||Protect All Cable Life is a good-quality cable maintenance product. You can also use engine oil (but it’s a bit messy)|
|Chain maintenance||A good kit to have on hand is the Motul chain care kit — including lubricant, cleaners, a brush, and so on.|

General information about the Triumph Bonneville Bobber
The Triumph Bonneville Bobber and Bobber Black is a factory custom (if that makes sense to you) from Triumph. They rebuilt their 1200cc “High Torque” platform in a motorcycle that’s part cruiser, part standard… the single-seated bobber.
At the heart of the Bobber is a category-leading, high-torque (HT) Bonneville 1200cc engine with a dedicated Bobber tuned for even more torque and power low down, and a beautiful brushed stainless steel exhaust with twin skin ‘slash cut’ peashooter silencers.
The Bonneville Bobber has many premium finishes including special bronze Bonneville 1200HT engine badge, premium tank badges and the signature Triumph makers mark triangle.
The Bonneville Bobber has an extended service interval of 10,000 miles (16,000 km) contributing to a reduced cost of ownership.
The Bonneville Bobber is fitted with Avon Cobra tyres that have been developed specifically for the bike – 19 x 2.5in on the front and a wider 16 x 3.5in on the rear. for improved high-speed manoeuvrability with class leading stability.
The Triumph Bonneville Bobber Black has a few tweaks from the original Bobber. It’s not just painted. The differences are:
- The front wheel is smaller (16-inch), which makes it steer a little slower
- Brakes are bigger with twin Brembo caliprers on 310mm discs up front (hence different brake pads)
- 47mm Showa forks
- Cruise control
- LED headlight with running lights.
- And black paint
The Bobber Black outsold the standard Bobber by such a large margin that Triumph only sells one Bobber now, and it’s the Black one.
