Best Engine Oil for Triumph Bonneville T120

#1

Valvoline 798151 Motor Oil, Motorcycle, 32 Oz, 10W-40, Amber

Valvoline's 10W-40 motorcycle-specific formula suits the Triumph Bonneville T120 well, matching the viscosity range Triumph recommends for the parallel-twin engine across most riding temperatures. The 32 oz size covers a top-up without committing to a full oil change, useful between services. It's formulated without friction modifiers that can interfere with wet clutches. Caveat: always verify your specific model year's manual, as some T120 variants specify a 15W-50 under certain climate conditions.
