Triumph Trident 660 Buyers Guide & Review 2025

Why the Triumph Trident 660 Matters (Especially in the UK)

The Triumph Trident 660 is a proper gem in the middleweight world – a modern British roadster with just the right mix of style, punch, and everyday usability. It’s the bike that brought Triumph roaring back into the “first big bike” category, and UK riders clocked on fast. Light, lively and classy without being pretentious, the Trident has become a familiar sight on B-roads, bike meets and learner car parks (usually with someone nearby saying “go on, sit on it, it’s lovely”).

With its smooth triple engine, comfy upright ergos and surprisingly premium build for the price, it nails that sweet spot between fun and functionality. It’s as happy weaving through city traffic as it is hustling down twisties with a silly grin plastered across your visor.

What It’s Like to Live With

Imagine a bike that feels friendly on a Monday commute but properly perks up when you take the long way home. That’s the Trident. The 660 triple is buttery smooth low down and eager up top, giving you a dab of sportiness without ever being shouty. The riding position is relaxed, the controls are light, and the whole thing feels like it’s been built by people who actually ride (funny that).

It’s a brilliant machine for UK life: quick warm-ups on cold mornings, plenty of grunt for overtakes, and enough comfort that you don’t feel like you’ve done three rounds with a garden rake after a day out. Just fuel it, check the chain, and crack on.

Who It Suits

• A2 riders wanting a “proper bike” feel without getting overwhelmed

• Commuters who want style and quality without litre-bike running costs

• Weekend riders who live for twisty B-roads and scenic blasts

• Anyone wanting a sporty middleweight that’s still comfy day-to-day

• Riders who appreciate Triumph’s build quality and finish

Who It Doesn’t Suit (As Much)

• Long-distance touring fans who need proper wind protection

• Very tall riders who prefer big adventure ergonomics

• Track addicts chasing razor-sharp supersport precision

A2 Licence Info

The Trident 660 is fully A2 compliant with a restrictor kit and remains one of the best “step-up” bikes for new full-licence riders. It’s smooth, predictable and confidence-inspiring – and when you eventually de-restrict it, the full-power version feels fresh again without being intimidating.

Impartial Review

Key Specs (Typical Triumph Trident 660)

Specs vary by year and any optional accessories – always check the exact bike you’re viewing.

Running Costs (Real UK Ownership)

Triumph built the Trident to be wallet-friendly, and it shows. Servicing is straightforward, insurance is sensible, and consumables aren’t eaten alive by excessive weight or power.

Fuel Economy

Expect around 50-65 mpg depending on how enthusiastic you are with that lovely triple soundtrack.

Insurance

Generally sits on the cheaper side of the middleweight class thanks to sensible power and strong safety features.

Servicing Costs

The 660 motor is simple for Triumph dealers and independent garages alike. Routine servicing isn’t bank-breaking.

Tyres & Consumables

Lightweight chassis = better tyre life. Chains, pads and discs last well unless you live permanently at redline.

Service Intervals (Typical Guidance)

• Oil & filter: around every 6,000 miles
• Valve clearances: roughly every 12,000 miles
• Chain & sprockets: 12,000 – 20,000 miles with proper care
• Air filter: around 12,000 miles
• Brake fluid: every 2 years

Service history matters! Always look for receipts and stamps – they separate the cherished bikes from the “ah, that’ll do” ones.

Buyer’s Check List – Triumph Trident 660

The Trident is a solid, well-built machine. Still, there are a few common things worth a closer look when you’re out kicking tyres on a cold forecourt.

1. Quickshifter Function (If Fitted)

Many Tridents have the optional Triumph quickshifter. Make sure upshifts and downshifts feel smooth – clunky shifts can mean poor adjustment.

2. TFT Display & Switchgear

Check for condensation, dead pixels, or dodgy menu buttons. Triumph’s TFTs are generally reliable, but always worth a look.

3. Corrosion Check

UK winters love a nibble at:

• Exhaust headers
• Fasteners around the engine
• Brake components

4. Suspension Feel

Stock suspension is decent, but budget-oriented. If it feels overly soft or bouncy, fresh oil or an upgrade may be due.

5. Tyres & Rider Habits

The Trident attracts newer riders – look for squared tyres or uneven wear. Could hint at heavy commuting or… creative cornering skills.

6. Low-Speed Drops

Naked bikes often suffer cosmetic battle scars. Look for bar ends, footpegs, engine covers and levers for clues.

7. A2 Restrictor Paperwork

If buying a restricted one, the certificate matters just as much as the kit. Insurers care, and you should too.

Red Flags

• No service history or long gaps between services
• Strange rattles on cold start
• Oversensitive clutch bite or sticky throttle
• Mismatched panels or fresh paint with odd overspray

Not sure? Bring a mate, a mechanic, or pop into the Lid Life community. No such thing as a daft question when it’s your hard-earned cash on the line.

Final Verdict: Should You Buy a Triumph Trident 660?

If you want something stylish, friendly, great for UK roads and properly fun without being overwhelming, the Trident 660 is a blinder. It’s the definition of a “sweet spot” bike – that perfect blend of easy-going manners and lively performance.

It brings Triumph’s premium feel to riders who don’t want a massive engine or massive bills. Whether you’re stepping up from A2, downsizing, or just after a bike that makes every ride a little better, it’s a class act.

Why Riders Love It

• Speedy, smooth triple engine
• Light, flickable and brilliant on B-roads
• Affordable to run and maintain
• Great for newer riders and seasoned commuters alike
• Looks way more expensive than it is

Rivals to Consider

• Yamaha MT-07
• Honda CB750 Hornet
• Kawasaki Z650
• Suzuki GSX-8S
• Aprilia Tuono 660
