Honda CB750 Hornet (2023+) Complete Maintenance Schedule and Service Intervals

This is the maintenance schedule and service intervals for the Honda CB750 Hornet — sourced from the owner’s manual, referencing parts diagrams.

The Honda CB750 Hornet is based on a 755 cc liquid-cooled parallel twin motor with a 270-degree crankshaft. It runs an 11.0:1 compression ratio, and manages to push out an impressive 67.5 kW (92 hp) at 9500 rpm, even when running on standard unleaded (91 RON).

The Honda CB750 Hornet isn’t really a successor other than in name to the 2nd generation CB600 Hornet, though it does share some style elements, as it does with the 1st generation CB1000R.

The CB750 Hornet was co-released with the Honda XL750 Transalp, which shares a motor.

Maintaining Your Chain on the Honda CB750 Hornet

It’s important to maintain your chain on the CB750 Hornet, as on any chain-driven motorcycle. 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.

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 necessary
Target slack: 25-35 mm
600 mi / 1000 km
Chain maintenance — Honda CB750 Hornet

Notes:

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

To measure chain slack on the CB750 Hornet, measure the free vertical movement of the chain. Make sure the motorcycle is in neutral, on a level surface, on its kickstand, and with no luggage or anything on it.

Target chain slack for the CB750 Hornet: 25-35 mm

If the slack is out of spec, you need to adjust it. The general procedure to adjust chain slack is to

  1. Loosen the rear axle
  2. Loosen the lock nuts for the chain slack adjusters
  3. Turn the adjusters equally, making sure alignment is kept by looking at the markers on either side, until the target chain slack is reached
  4. Re-tighten the axle, then re-tighten the adjusters.

Tire sizes and pressures for the Honda CB750 Hornet

The manual says that the Honda CB750 arrives shod with Dunlop Roadsport 2 or Michelin Road 5 tubeless tires.

Here are the tire sizes and recommended pressures. Naturally, modify the tire pressures to suit your riding style.

About the Honda CB750 Hornet

The Honda CB750 Hornet is a new model in the Honda line-up, and also a new model in the long string of motorcycles with the Honda CB moniker, many of which are still made.

The CB750 Hornet is sold alongside several other middleweight sport bikes from Honda, including the Honda CB500F and Honda CB650R, both of which serve slightly different markets from the CB750 Hornet. But there’s a lot of overlap.

Where the CB750 Hornet is different from the others is that it has a new engine concept for Honda — a parallel-twin engine with a 270-degree crankshaft. These engines have become in vogue of late, ever since the Triumph and Yamaha parallel twins brought them into mainstream consciousness. They’re known as being an excellent balance between torquey and powerful, and can have the character of a Ducati V-twin but with much easier maintenance, thanks to the fact that they have just one cylinder head, and don’t have the rear cylinder cooling and access problem that V-twins have.

The engine in the Honda CB750 Hornet is a 755cc parallel twin with a single overhead cams and four valves per cylinder. It is of a “unicam” design, an intentional single overhead camshaft.

Per Honda, the Unicam design is intended to combine the best features of single- and double-overhead camshafts. The Unicam design means less weight and less space taken up in the cylinder head. The camshaft sits lower in the head, which makes for a more compact engine and lower centre of gravity.

Honda has implemented the Unicam design in a bunch of off-road / motocross motorcycles, starting with the CRF450R, but more recently also in the CRF1000L / CRF1100L parallel twins.

The Unicam is a distinct differentiator for the CB750 Hornet vs Suzuki’s competitor to the Hornet, the GSX-8S, which they released the same year.

Aside from the novel engine, there’s quite a lot that’s novel and interesting about the Honda CB750 Hornet.

Firstly, it’s the first Hornet motorcycle to have a parallel twin motor. They have all had inline four-cylinder engines in the past.

Secondly, the CB750 Hornet has quite a bit of standard tech. It comes with a highly legible 5-inch colour TFT display, ride modes (including a custom one), traction control (known as Honda Selectable Torque Control), wheelie control, an assist/slipper clutch, and even an optional up/down quick-shifter.

Thirdly, despite all the updates, the CB750 Hornet still strikes a balance between features and affordability. It omits a few things that are present on high-end naked bikes, like cornering ABS, cruise control, and adjustable suspension. Like the previous Hornets, it’s trying to be “just enough bike” without presenting an overwhelming amount.

The Honda CB750 Hornet comes in a few options packs, including a sport pack, style pack, and touring pack. If you want the adventure touring pack… then you’re probably looking for the XL750 Transalp.
