What you need to service a Triumph Bonneville T120
Triumph recommends many specific kinds of consumables for their motorcycles with the 1200cc engine.
Here’s a list of the things you need to service your Triumph Bonneville T120.
|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 K&N’s KN-204-1.|
|Brake fluid||Triumph 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||Standard brake pads code is T2026565. The equivalent part number for EBC brakes is FA604/4HH.|
|Rear brake pads||Use original part number T2022955. The equivalent part number for EBC brakes is FA214/2HH.|
|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 part number for the air filter is T2201122. You can also use K&N part TB-1216.|
You also need the following general consumables for servicing your Triumph Bonneville T120.
|Chain lubricant||The chain needs to be lubricated every 800 km/500 miles (or more, if it gets wet/dirty). Motul chain paste is cheap and well-loved.|
|Chain cleaner brush||A chain cleaner brush makes cleaning off grime and then distributing new lubricant much more easy.|
|Paddock stand||Lubricating the chain and changing the oil both become a lot easier once you use an affordable paddock stand.|
|Cable lubricant||Remember to lubricate your clutch cable (and brake cables if you have them) with a cable lubricant. Protect All Cable Life is a good general-purpose lubricant.|
|Grease||Get a good lithium soap based grease for lubricating major components like your side stand, centre stand, and bearings.|
