Is the Triumph Speed 400 A2 licence legal?

Yes, the Triumph Speed 400 is fully A2 licence compliant. With 39.5 bhp (40 PS) and 37.5 Nm of torque, it fits within the A2 power-to-weight limits without requiring a restrictor kit.

What are the service intervals for a used Triumph Speed 400?

The Speed 400 features a single-cylinder engine with a class-leading service interval of 10,000 miles or 12 months, whichever comes first. This makes it one of the most cost-effective premium bikes for UK commuters.

Can you get a used Triumph Speed 400 on PCP finance?

Used Triumph Speed 400s are popular for PCP (Personal Contract Purchase) due to their strong residual values. By 2026, many early models are entering the second-hand market, allowing riders to refinance or start new agreements with lower monthly payments than new models.

The Speed 400 is Euro 5+ compliant and meets all current ULEZ (Ultra Low Emission Zone) and Clean Air Zone requirements across the UK, meaning you can ride in London and other major cities without paying daily charges.

What should I check when buying a used Triumph Speed 400?

The Speed 400 is a 'thumper' (single-cylinder), but it is widely praised for its refinement. When buying used, ensure the V5C logbook is present and check for a full Triumph dealer service history, as this preserves the manufacturer's warranty and resale value.

Is the Triumph Speed 400 suitable for shorter riders?

The Speed 400 has a seat height of 790mm and a wet weight of 170kg. Its slim profile and accessible height make it a top choice for shorter riders and those transitioning from a 125cc CBT bike.

Used Triumph Speed 400: 2026 UK Buyer’s Guide & A2 PCP Values

The Modern Classic Disruptor: Why the Speed 400 is Still King in 2026

When Triumph launched the Speed 400 in late 2023, it didn't just enter the small-capacity market; it redefined it. Fast forward to May 2026, and the used Triumph Speed 400 has become the primary target for UK riders graduating from their CBT or those seeking a stylish, premium-feeling commuter that doesn't break the bank.

As the bike enters its third year on UK roads, the second-hand market is thriving. For those holding an A2 licence, the Speed 400 remains arguably the most polished "first big bike" available. At CarsLink.ai, we’ve tracked the market shifts, and despite the arrival of newer competitors, Hinckley’s single-cylinder roadster holds its value remarkably well.

Understanding the Speed 400 Specs

Before diving into the used prices, it’s vital to understand what you’re buying. The Speed 400 isn't just a "budget" bike; it’s a scaled-down Triumph through and through.

Feature	Specification
Engine	398cc liquid-cooled, 4-valve, DOHC, single-cylinder
Power	40 PS (39.5 bhp) @ 8,000 rpm
Torque	37.5 Nm @ 6,500 rpm
Weight (Wet)	170 kg
Seat Height	790 mm
Licence Type	A2 Compliant (No restrictor kit needed)
Service Interval	10,000 miles / 12 months

The TR-series engine is the star here. It’s punchy, characterful, and remarkably smooth for a "thumper." In the 2026 market, these bikes are often found with 4,000 to 12,000 miles on the clock, making them ideal candidates for PCP (Personal Contract Purchase) refinancing or straightforward used buys.

2026 Used Market Report: What Should You Pay?

The initial "hype tax" of 2024 has subsided, leaving the used Triumph Speed 400 at a very competitive price point. Because Triumph maintained a strong RRP throughout 2025, residual values have stayed firm.

Current 2026 Price Guide:

Mint (Sub-3,000 miles, 2025/26 plate): £4,400 – £4,700
Good (5k-10k miles, 2024 plate): £3,800 – £4,200
High Mileage/Workhorse (15k+ miles): £3,300 – £3,600

Triumph PCP deals 2026

For A2 riders, PCP remains the most popular way to get on two wheels. Many 2024/25 models are now coming off their original two-year agreements, creating a surge of "Approved Used" stock at dealerships.

Typical Used PCP Example (2024 Model at £3,950):

Deposit: £500
Term: 36 Months
Annual Mileage: 4,000
Monthly Payment: Approx. £75 - £85
Optional Final Payment (GFV): £1,800

Buying used on PCP in 2026 is often more cost-effective than a bank loan for younger riders, as it keeps monthly outgoings low while you gain the "No-Claims Bonus" (NCB) required to move up to a Street Triple or Tiger 900 later.

What to Check When Buying Used

While the Speed 400 is generally robust, there are specific areas to inspect when viewing a used machine:

Finish and Corrosion: Look closely at the engine casings and exhaust downpipe. Like many bikes in this price bracket, if they haven't been treated with anti-corrosion spray (like ACF-50) during UK winters, the fasteners can show signs of furring.
Service History: The 10,000-mile service interval is generous, but Ensure the V5C matches the seller and that the initial 600-mile "break-in" service was recorded by an authorised Triumph dealer.
Chain and Sprockets: Many Speed 400s are used as daily commuters. Check for "hooked" sprocket teeth or tight spots in the chain, which suggest a lack of regular lubrication.
Recall Status: Check the DVSA website or ask the dealer if the early 2024 software updates (related to stalling issues some riders reported) were applied. By 2026, most bikes on the market should have been rectified.

The A2 Licence Context

The Speed 400 is a "native" A2 bike. Unlike larger bikes (like a restricted Z900 or MT-07), the Speed 400 was designed specifically for this power output. This means it is lighter, more agile, and offers a better power-to-weight ratio than many heavier, restricted machines.

For riders who have just passed their Module 1 and Module 2 tests, the Speed 400 offers a confidence-inspiring 790mm seat height. It’s narrow, making it easy to get both feet flat on the floor at traffic lights—a huge plus for new riders in congested UK cities.

Running Costs & UK Legislation

In May 2026, the cost of biking remains a key factor.

Road Tax (VED): As a 398cc machine, you sit in the £50-£60 annual bracket (check current 2026 DVLA rates as these track inflation).
Insurance: Generally sits in group 9 or 10. For a 19-year-old on an A2 licence in a major city, expect premiums to be the biggest hurdle. Always get a quote before committing.
ULEZ/Clean Air Zones: The Speed 400 is fully Euro 5+ compliant. You can ride into London, Bristol, or Birmingham without worrying about daily charges.
