Triumph Daytona 660 (2022+) Maintenance Schedule / Service info
This is the maintenance schedule for the Triumph Daytona 660, a mid-size road-going sport bike from Triumph released in 2024, including the A2 / LAMS-approved version.
The Triumph Daytona 660 inherits the legacy of the Daytona from the high-powered, and recently track-focused sport bikes, like the Triumph Daytona Moto2 765, but is really a sport bike / fairing-equipped build of the Triumph Trident 660, released in 2021.
The Daytona 660 is a more focused sport bike than its Trident or Tiger Sport 660 stablemates. The engine is tuned for more peak power, with 95 PS (70 kW / 94 bhp) at 11,250 rpm. The brakes are higher spec (with 4-piston radial calipers, vs 2-piston sliding calipers), and the riding position is significantly sportier.
The Daytona 660 is also available in learner-legal form in many markets, including Europe, the UK, Australia, and New Zealand. Parts and maintenance are the same — it’s restricted but nothing fundamentally changed in the build.

Triumph Daytona 660 Drive Chain Maintenance
Maintain your drive chain regularly — not just at major services. If you use your Daytona at the track or ride through rain or get the chain wet from washing, you should clean and lube it right away.
Below is the recommended schedule for maintaining the Daytona 660’s chain per the manual.
| Item | Every |
|---|---|
| Drive chain – Check slack, adjust as necessary See below for guidance | Pre-ride |
| Drive chain – lubricate | 200 miles (300 km) |
| Drive chain – wear check | 500 miles (800 km) |
Checking chain slack
To check the slack on the Daytona 660, put the motorcycle in neutral, onto its kickstand, and on a level surface. Make sure there is no luggage or load on the bike.
Check the slack on the lower part of the chain, midway between the sprockets, and check it in multiple places (move the motorcycle forwards and backwards) as chains wear unevenly.
Slack on the Triumph Daytona 660 is defined as the free movement of the chain in the loosest part.
Target chain slack for the Triumph Daytona 660: 43-55 mm (1.7 – 2.15 in)
If the chain slack is out of spec, you need to adjust it.
Adjusting chain slack
To adjust the chain slack on the Daytona 660, follow the steps below. The goal is to set it to 43 mm (or slightly more) to allow slack to increase with chain wear.
- Loosen the rear axle nut with a breaker bar and the lock nuts on either side of the axle.
- Turn the adjuster nuts to tighten (or loosen) the chain. Keep checking the chain tension to see if it has come within spec to 43 mm, give or take (the manual indicated 43-46 mm).
- Keep an eye on the adjuster alignment on either side of the axle. Make sure that the adjustment is to the same point so the chain and wheel remain aligned.
- When you’re done, tighten the axle to 110 Nm / 81 lb-ft.
- Re-check the chain slack again to make sure it’s still within spec.
- Tighten the adjuster nuts to 3 Nm / 2 lb-ft
- Tighten the adjuster lock nuts to 15 Nm / 11 lb-ft.
Wheels, Tyres, and Tyre Pressures
The Triumph Daytona 660 ships with Michelin Power 6 tyres stock, but the very standard sportbike-spec rims will take a wide variety of street, sport touring, and sport tyres.
Below are the recommended tyre pressures when cold.
| Wheel | Rim size | Tire size | Tire pressure (cold) |
|---|---|---|---|
| Front | 17 x 3.5 in | 120/70 ZR 17 58W | 2.35 bar / 34 psi |
| Rear | 17 x 5.5 in | 180/55 ZR 17 73W | 2.90 bar / 42 psi |
About the Triumph Daytona 660
The Triumph Daytona 660 is an entry-level sport bike, or put another way, a versatile all-rounder sport bike that can do everything from daily commuting to weekend fun with grace.
It inherits the legacy of the Daytona 660 from bikes of the same name of the past, most recently the high-spec Moto2 only 765-powered motorcycle. But it most resembles something like the base-spec Triumph Daytona 675 of around a decade prior.
Of course, the Triumph Daytona 675 was a different bike, intended to compete directly with 600 cc-class sportbikes. The Daytona 660 is intentionally different.
The engine in the Daytona 660 is Triumph’s peachy 659 cc three-cylinder engine, an engine intentionally designed for street riding. Its sub-660 cc capacity means that it slides in under learner-legal capacity limits in most parts of the world. The same is true of the peak power, which can’t be higher than 95 PS (the rule is that the peak power of the unrestricted bike can’t be double a learner bike’s restricted peak power of 35 kW / 48 PS).
The engine is a spritely motor with a flat torque curve and great sound, especially considering this is a mid-range motorcycle built relatively on a budget.
There have been a plethora of middleweight sport bikes that have come on the market as late. They span a range of power and technology levels — as well as budgets — to cater to a wide variety of needs. The Daytona is at the entry-level end of the range, something like a Honda CBR650R — which has an engine that makes very similar power and has a similar level of spec in its suspension and brakes.
Despite being “entry-level”, there’s a lot that riders of every level can get excited about. The Daytona 660’s 70 kW / 95 PS is nothing to be sneezed at, and is plenty for carving up tighter winding roads or everyday riding pleasure. The engine sings past 12,000 rpm — an engine speed few reach often on high-end sportbikes in everyday riding. And while there’s limited adjustability in the suspension, it’s sure to be enough for most people’s everyday needs, while also being cheaper to service (or replace).
Finally, there are no other three-cylinder options for those looking for a learner-legal motorcycle in Australia/NZ, Europe, or the UK. Since the Triumph Daytona 660 can be detuned to fit within power limits, it is distinct from both its bigger sibling, the Street Triple range, as well as from Yamaha’s MT-09.
The Daytona 660 has higher spec than its Trident / Tiger Sport stablemates, which share a similar spec level (though the Tiger Sport 660 has much more protection and a little more weight as a result). Below is a summary of the difference.
| Model | Trident 660 / Tiger Sport 660 | Daytona 660 |
|---|---|---|
| First model year | 2021 (Tiger Sport 2022) | 2024 |
| Peak power | 60 kW / 81 PS / 80 bhp @ 10,250 rpm | 70 kW / 95 PS / 94 bhp @ 11,250 rpm |
| Peak torque | 64 Nm (47 lb-ft) @ 6,250 rpm | 69 Nm @ 8,250 rpm |
| Compression ratio | 11.95:1 | 12.05:1 |
| Front suspension | Showa 411mm SFF USD | Showwa 41mm SFF-BP USD |
| Front brakes | 2 x 310 mm discs, 2-piston sliding calipers | 2 x 310 mm discs, 4-piston radial calipers |
