The Hornet 2.0 tyre size combo is a 110/70-17 steering tyre with a 140/70-17 driving tyre, tubeless, mounted on 17 inch cast wheels. Honda lists them with the codes 54S and 66S.
This 184 cc streetfighter gets a fatter front tyre than the older Hornet 160R, and it rides on an upside down fork, so its tyres work harder under braking. Below you will find the codes explained, how to choose replacements and a short section on the horn, which owners often upgrade at the same visit.

Honda Hornet 2.0 tyre size chart
| Position | Size | Load and speed | Wheel |
|---|---|---|---|
| Front | 110/70-17 | 54S | 17 inch alloy |
| Rear | 140/70-17 | 66S | 17 inch alloy |
All Hornet 2.0 bikes use these sizes. The Hornet 160R that came before used a narrower 100/80-17 front with the same 140/70-17 rear, so do not assume an old front tyre from that bike will suit the newer one.
Reading 54S and 66S
Load index 54 means the front tyre can carry 212 kg; 66 on the rear means 300 kg. The S letter certifies 180 km/h, comfortably past this bike's top speed. When you buy, match or beat both codes. A bargain tyre rated lower on load may wear fast and feel vague two up with luggage. See our speed rating page for the letter chart.
What the Hornet 2.0 tyre size means for handling
The front 110/70-17 stands about 586 mm and the rear 140/70-17 about 628 mm. That broad, low front spreads a big footprint when you brake hard, a good match for the inverted fork and petal disc. The rear's 98 mm wall cushions potholes better than lower profile options, a good match for city roads full of patchwork.
A 150/60-17 rear tempts owners chasing a beefier stance. It stands near 612 mm, around 2.5 percent shorter, and can touch the chain or swingarm. Honda never fitted one, so that gamble is yours.
Pressure and puncture care
Honda's cold inflation values appear in the Hornet handbook plus a sticker on the frame; switch to the raised rear number with a passenger. Check weekly, since tubeless tyres lose air slowly and the bike still feels fine until it squirms in a corner. Tread punctures normally accept a mushroom plug or external string; damage near the shoulder or wall needs a specialist's eye. Bike tyre pressure has a full checking routine.
Horn on the Hornet 2.0
Many owners find the stock horn too soft in heavy traffic and upgrade it when they visit the tyre shop. Before you do, note three points:
- A louder twin horn draws more current. Fit a horn relay so the handlebar switch does not burn out.
- Check that the bracket clears the radiator shroud and front mudguard at full steering lock.
- A loud horn does not replace good braking tyres; use it to warn, not to clear the road.
The bike horn guide explains horn types, and horn switch covers fixing a button that sticks or fails.
When to replace Hornet 2.0 tyres
- Tread worn flush with the indicator ridges, or a flattened band across the rear's middle.
- Cracks in the grooves or tyres older than five years by the date code.
- Cuts, bulges or exposed cords: stop riding and get the tyre checked at a shop.
- A front that feels like it falls into turns: often uneven wear from low pressure.

Questions owners ask
Which honda hornet 2.0 tyre size goes on each wheel?
Request 110/70-17 54S for the front wheel and 140/70-17 66S for the back, tubeless, to suit the 17 inch cast rims.
Is the Hornet 2.0 front tyre different from the Hornet 160R?
Yes. The Hornet 2.0 uses a wider 110/70-17 front, while the 160R used 100/80-17. Out back both share 140/70-17.
Is a 150 width rear possible on the Hornet 2.0?
Honda never offered it. A 150/60-17 rides lower and may graze the chain, so any such swap is unofficial.
Are Hornet 2.0 tyres tubeless?
Yes, both tyres are tubeless on alloy wheels from the factory.
Do I need a relay to fit a louder horn?
Yes for most twin or high current horns. A relay protects the handlebar switch and wiring from overload.
