Honda CB350 H’ness and CB350RS maintenance schedule

Honda CB350 H'ness in front of wall

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.

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 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.

It 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 — a country dominated by around 100cc-class motorcycles.

The CB350’s single-cylinder engine has 348cc displacement. It’s fuel-injected, air-cooled, DOHC, 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).
