The NC750X is Honda's pragmatic 745 cc parallel-twin crossover, famous for its 22,000-mile valve-check intervals (unusual screw-type clearance checks), frugal 70+ mpg consumption and a storage compartment where the fuel tank normally sits. The 2016 refresh grew displacement from 670 to 745 cc; the 2018-2021 generation documented here added LED lighting and optional DCT. Service data per the 2018 US manual: 3.4 L of 10W-30 oil with the filter (the DCT XD versions take marginally more), long-life iridium IFR6G-11K plugs gapped at a wide 1.0-1.1 mm, 1.69 L coolant and a 114-link 520 chain. The big YTZ14S battery reflects the DCT's hydraulic pump needs.
