Honda CB350 H’ness and CB350RS maintenance schedule

This is the maintenance schedule and service intervals for the Honda CB350 H’ness and CB350RS, also known as the Honda H’Ness, depending on market.

It’s known as the Honda H’Ness in India and the Honda CB350 in other markets. Some markets also get the Honda CB350RS, a slightly more up-spec and sporty machine with the same engine, chassis, and ride gear.

All versions of the Honda H’Ness and Honda CB350 share the same foundation: a 348cc 4-stroke single-cylinder engine that makes 15.5 kW (21 hp) @ 5,500 rpm or 30 Nm (20 ft-lb) @ 3,000 rpm, and maintenance is the same for all of them.

Honda H’Ness CB350 Maintenance Schedule

Maintaining Your Chain on the Honda CB350 H’ness

It’s important to maintain your chain on the CB350, as on any chain-driven motorcycle, but particularly as many Honda CB350s are ridden in areas of varying road quality.

Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain. You can also use a heavy weight gear oil.

Honda recommends you follow the following chain maintenance schedule:

Chain maintenance itemEvery
Check drive chain lubrication condition, lubricating if necessary600 mi / 1000 km
Check drive chain slack, adjusting if necessary600 mi / 1000 km
Chain maintenance — Honda CB350 H’ness

Notes:

  • Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your CB350 in dusty or rainy conditions.
  • Always lubricate the chain after washing the motorcycle.

Honda CB350 H’Ness Pre-ride checks

Honda also suggests the following pre-ride checks daily or before rides (if it’s not used daily). Many of these can be done as part of the normal start-up procedure, but make a habit of checking the oil and brake pads.

About the Honda CB350 H’Ness

Honda CB350RS Red and Yellow
Honda CB350RS – two colours side by side

The Honda H’Ness CB350 and Honda CB350RS are compact, simple, stylish, and affordable standard motorcycles from Honda.

They’re designed to compete with Royal Enfield motorcycles like the Royal Enfield Meteor 350. Royal Enfield has dominated sales in India for a very long time and is gathering a loyal following elsewhere.

The CB350 is powered by an engine that’s considered small for many of Honda’s motorcycle markets like in Europe, the UK, and the US, but which is considered big in India and many other less developed markets — areas dominated by around 100cc-class motorcycles.

The CB350’s single-cylinder engine has 348cc displacement. It’s fuel-injected, air-cooled, and makes just shy of 16 kW or 21 hp. Which is enough for low-speed highway cruising and most of what the CB350 is meant to do, which is urban commuting while looking cool.

The Honda CB350 H’ness is built to a high spec. Sit on it and you’ll notice the parts gleam and the paint is rich. So this is a bike designed to be an upgrade for aspirational riders who still want to get from A-B but want to do so in stile and with a touch of prestige.

It power to the ground through a five-speed transmission and a chain drive.

The focus of the Honda H’Ness CB350 is simplicity. It’s a simple motorcycle to ride — and a great motorcycle as a first rider. And owning it and maintaining it simple too, as evidenced by the maintenance schedule, where even valve service intervals are listed as something anyone can do.

The maintenance for the CB350 is a lot less intense than on the Royal Enfield motorcycles, too. Intervals are wider, and there are less items to worry about.

Many international markets that haven’t received the CB350/H’ness have been wondering — why don’t we get it, too?

By the way, H’ness is short for “Highness” and is intended to be a nod to the majestic nature of the Honda CB350.

Manual for the Honda CB350 H’Ness

The above maintenance schedule came straight from the manual for the Honda H’Ness, double checked with the manual for the Honda CB350RS (it’s the same).
