Honda CB400SF (2008-present) Maintenance Schedule

Honda CB400SF Super Four Hyper VTEC Revo

This is the maintenance schedule for the Honda CB400SF, Honda’s compact 4-cylinder naked sportike, made from 2008-today in its present mechanical configuration.

The Honda CB400SF is also known as the Honda CB400 Super Four.

Before 2008, the Honda CB400SF was carburettor fed. There were two previous distinct generations — first the four-cylinder roadster (a.k.a. the CB-1) made between 1992 and 1997, then the VTEC-actuated carburettor fed version from 1999-2007, during which period the VTEC system was iterated on and refined.

The CB400SF, whose full name is the CB400SF Hyper VTEC Revo, so named because by the time you finished saying it you’ll have reached 60 mph/100 km/h, is a compact 4-cylinder naked sport bike built to a high build quality standard. It’s one of two Honda bikes with variable valve timing, the other being the VFR800 and VFR800X.

Maintenance for the CB400SF is much the same as for any other four-cylinder naked bike — it’s chain-driven with a six-speed gearbox. The 2008+ models came with optional ABS but that doesn’t affect the maintenance schedule.

About the 2008+ Honda CB400SF “Hyper VTEC Revo”

OK, so you’ve gotten past the long name of the Honda CB400SF and you want to know what the bike is about.

In a nutshell, the CB400SF is a compact 4-cylinder rocketship. It’s a high quality naked standard built to a premium. This isn’t your average learner bike where it’s obvious a manufacturer cut corners; this was a classic and Honda knew it even as they were making it.

An evolution from the earlier generations’ carburettor-fed models, the modern 2008+ Honda CB400SF is built around a 399cc liquid-cooled DOHC 4-valve-per-cylinder fuel-injected engine. In stock trim it makes 40 kW (53 hp) @ 10,500 rpm, with a slight bump in power after 2017 to 41 kW (55hp) @ 11,000 rpm.

Unfortunately, the 2017+ models are Japan-only, unless you get a custom import.

The Honda CB400SF isn’t light in weight, even though it’s a compact bike. For larger individuals it can feel a little small (not like a compact bike, but just not like. large on), particularly if they wind on the accelerator and find the little machine taking them north of 140 km/h (90 mph), which it will do with relative ease.

The CB400SF weighs nearly 200 kg, especially with ABS (a commonly chosen option) and doubly especially if you get a Bol D’or package from Japan.

Common mods to the CB400 motorcycles are new exhausts to open up the VTEC sound and suspension mods to make them sportier.

But they’re already becoming rare and somewhat collector’s items since they were no longer exported from Japan.

Manual for the Honda CB400SF

The above maintenance schedule came straight from the manual with minimal modification.

The manual for the Honda CB400SF is available from Honda websites in countries in which it was released, like Japan. You can download it from Honda’s website here.
