Triumph Daytona 600: A 21st Century Sportbike Gem

The Triumph Daytona 600 burst onto the scene in 2003, tasked with a monumental job: to erase the memory of its predecessor, the ill-fated TT600. While it shared the TT600's underpinnings, the Daytona received a significant 'new set of clothes' which included a vastly improved fuel-injection system, significantly more attractive styling, and a revised chassis. These changes were enough to elevate it from a questionable proposition to a genuine contender in the highly competitive supersport arena, even going on to win at the Isle of Man TT. In a market dominated by the likes of the radical Honda CBR600RR and Kawasaki ZX-6R, and the established Suzuki GSX-R600 and Yamaha YZF-R6, Triumph's achievement with the Daytona 600 was nothing short of remarkable. It masterfully struck a balance between sporty aggression and everyday practicality. Its agile chassis delivered handling sharp enough to impress even on a track, yet it combined this with a surprisingly comfortable and accommodating riding position, appealing to those who found the dedicated track machines a little too extreme. In 2005, Triumph introduced the Daytona 650 as a stop-gap model, offering a touch more mid-range punch before the arrival of the iconic Daytona 675 triple in 2006. While the 675's triple-cylinder engine immediately captured headlines, the earlier inline-four Daytona 600 and 650 remain far more user-friendly and compliant road bikes compared to their more focused triple sibling. If you're a rider with a penchant for British engineering (and importantly, a bike actually built in the UK), the Daytona 600 or 650 represent excellent value on the used market.

Triumph Daytona 600 and 650 (2003-2006) Price Guide

The Daytona arrived during an era when supersport motorcycles were still relatively accessible, meaning that even today, used prices remain quite reasonable. You might find a 'tatty' Daytona 600 for around £1500 in a private sale, though this often implies some cosmetic damage or a higher mileage. To secure a tidier example, it's advisable to increase your budget to the £2000-£2500 range. With this budget, you're in a strong position to acquire either a well-maintained Daytona 600 or a 650, whether from a dealer or a private seller. Opting for a private sale might carry a slight risk, but it can often be offset by a price saving and a potentially lower mileage. Ideally, the Daytona 650 is the preferred choice due to its improved mid-range performance and a noticeably slicker gearbox action. However, don't be discouraged if your search yields only a Daytona 600; it remains a very capable and enjoyable motorcycle.

Pros and Cons: A Balanced View

Engine and Performance: More Than Meets the Eye

Given that the Daytona's engine was a derivative of the TT600's unit, expectations for its performance in 2003 were somewhat muted. However, the Daytona delivered a genuine surprise. Despite being quoted with around 10bhp less than its contemporary rivals, the Daytona's real-world performance, especially on the road, told a different story. This is a sensation that holds true even today. While a bike like the Honda CBR600RR might leave you feeling slightly underwhelmed by its lack of mid-range, forcing you to constantly work the gearbox or rev the engine hard, the Daytona (along with the GSX-R600 and the larger-capacity ZX-6R) offers a significantly more accessible spread of power. This translates to less rider effort and a more relaxed, enjoyable experience on the road. With a claimed 112bhp (translating to a genuine 100bhp at the rear wheel), the Triumph is by no means slow. The fuel-injection system is a monumental improvement over the TT600's setup, but it's the smooth acceleration and the punchy mid-range torque that truly set the Daytona apart. The Daytona 650, featuring a longer stroke engine rather than a larger bore like the Kawasaki's 636cc unit, offers even more low-down grunt.

However, no motorcycle is without its quirks, and the Daytona has a few mechanical considerations to be aware of when purchasing a used example.

Common Daytona Quirks and How to Address Them

One common issue, shared with many Suzuki models, is the clutch cut-out switch. Similar to a sticky sidestand cut-out switch, this can also affect the Daytona. If the bike fails to start, this is one of the first places to check. The switch can not only become sticky but also wear in its mounting point, leading to erratic operation. While it's an easy part to replace, a liberal application of light oil can often resolve stickiness. The same applies to the sidestand cut-out switch, another frequent culprit for starting problems.

Delving deeper, the gearbox on the Daytona 600 warrants attention. It's known for its somewhat clunky and imprecise action, a trait that Triumph addressed in the improved 650 model. The primary cause of this is the gear linkages. Fitting aftermarket rearsets to the 600 can improve the feel, but the 650 benefits from a new linkage, a redesigned seven-plate clutch (two fewer plates than the 600), and a backlash-eliminating gear, making for a significantly better system. When inspecting a used Daytona, always ensure the gearbox shifts smoothly with no false neutrals. Also, look for any oil leaks around the shaft seal, which is known to be a weak point. While replacing this seal isn't a major undertaking, it can be fiddly, and any sign of leakage should be a cause for concern.

Regarding the fuel system, beyond the usual culprits like blocked air filters and the fuel filter (located within the fuel tank), it's crucial to inquire about when the throttle bodies were last balanced. The Daytona requires its throttle bodies to be balanced every 6000 miles, and the secondary air injection system reset every 12,000 miles. These maintenance tasks are often overlooked, and if neglected for too long, they can lead to rough running and a jerky throttle response. Curiously, if the bike has been left standing for an extended period, the engine management light can illuminate and remain stuck on. To reset it, the engine needs to go through three complete heat cycles: start the bike and let it run until the cooling fan activates; repeat this process twice more. If the light persists, it's a cause for concern.

Provided these points are addressed, and the ECU fuel map is updated if an aftermarket race can is fitted, the Daytona's engine is generally robust. Ensure the valve clearances have been checked at the recommended 12,000-mile intervals. Thankfully, the engine bay is relatively roomy, making this a more accessible and less costly job than on more compact modern supersport bikes. Regular oil and filter changes are also essential for maintaining engine health.

It's worth noting that while a 34bhp restrictor kit was available for the Daytona, it cannot be made A2-legal. Triumph's original claim of 112bhp means it falls outside the performance criteria for restriction under current regulations.

Handling & Suspension: A Surprising Competitor

In 2003, the Daytona's handling capabilities were a revelation. Despite not being as overtly track-focused as the ZX-6R or CBR-RR, the Triumph held its own impressively when pushed hard on a circuit. Its secret lay in its beautifully natural balance, which instilled confidence and allowed riders to push the limits. It's no coincidence that the Daytona achieved victory at the Isle of Man TT; the very qualities that make it a superb road sportsbike are precisely what's needed to tackle the challenging Manx course. Unflappable over bumps, the Daytona's suspension (featuring conventional forks) and brakes, while not the most exotic, perform exceptionally well. They deliver a plush ride coupled with more than adequate stopping power, further enhanced by standard braided brake lines. This is a bike that feels perfectly at home on the road, and the relaxed riding position allows for enjoyable miles without the fatigue associated with a more aggressive racing stance. The handling can be further refined with upgrades such as an aftermarket shock absorber, fork rebuild, high-friction brake pads, and a set of sticky tyres – relatively minor investments for significant improvements in both handling and performance.

When inspecting a used Daytona, there are no particularly unusual chassis-related issues to worry about. Perform the standard checks: examine the condition of the chain and sprockets, tyre tread depth, look for crash damage, check the suspension linkages (which require regular greasing), inspect for rounded fasteners, and broken fairing lugs. The main area of concern is the bike's finish. Sadly, the Daytona is somewhat lacking in this department, with corrosion and rust often found in hidden areas. A thorough inspection for corrosion is essential, as once it takes hold, it can be difficult to eradicate.

Comfort and Economy: A Practical Supersport

Considering its supersport classification, the Daytona offers a remarkably comfortable riding experience. Noticeably larger and more accommodating than rivals like the CBR-RR or the later Daytona 675, the 600 and 650 models are well-suited for longer journeys. While perhaps not ideal for extended touring, they are more than capable of day trips or short multi-day excursions. A taller screen can significantly reduce wind blast, thanks to the bike's generous fairing. Gel seat options and various soft luggage solutions are also available to enhance comfort and practicality.

In terms of fuel economy, you can expect figures in the mid-40s miles per gallon (mpg), translating to approximately 180 miles on a full tank, which is perfectly acceptable for a motorcycle of this type. Naturally, pushing the engine hard will see this figure decrease, but that is to be expected.

Equipment: Simple and Effective

The Daytona is a straightforward, old-school supersport machine, and as such, it lacks modern amenities like a fuel gauge or a gear indicator, let alone any advanced electronic rider aids. In many respects, this simplicity is a positive, as it reduces the potential for electronic failures. The good news is that it comes equipped with braided brake lines as standard, meaning this is one area where you won't need to spend extra on upgrades.

Triumph offered a range of accessories for the Daytona, including an alarm/immobiliser, carbon or stainless steel silencers (non-road legal), a taller screen, a tank bag, and various gel seat options. Typically, most used examples will feature an aftermarket exhaust (check if the bike has the associated 'performance' ECU upgrade, which was available through Triumph dealerships), a taller screen, and occasionally a tail tidy. It's less common to find a Daytona heavily adorned with accessories compared to its Japanese counterparts. If a gear indicator is desired, aftermarket units are available and are generally straightforward to fit, often being plug-and-play items costing around £100. Be cautious with older alarm systems, as they can often be more trouble than they are worth; if purchasing from a dealer, request its removal.

Rivals: The Supersport Landscape

The Daytona 600 will appeal to riders seeking a relatively affordable supersport bike that isn't excessively track-focused and is generally easier to insure, making it a suitable option for newer or younger riders. This positions it against earlier generations of supersport machines such as the Honda CBR600F Sport, early Suzuki GSX-R600 models, or the Kawasaki ZX-6R (often the 636cc variants).

Verdict: A Surprisingly Capable British Sportster

The Triumph Daytona 600, and particularly its successor the 650, represent excellent choices for road-going supersport motorcycles. Their pleasingly roomy ergonomics and Triumph's masterful tuning of the Daytona's chassis make for an immensely enjoyable experience when attacking corners, without sacrificing the crucial elements of compliant suspension and rider comfort. Available at relatively low prices on the used market, the Daytona, while undeniably not as meticulously built or as flashy as some of its Japanese rivals, is a far more accommodating machine. This makes it a superior choice for riders who have little to no interest in track riding. Put the TT600 debacle behind you, opt for a Daytona 600 or 650, and prepare to be pleasantly surprised. It may not be perfect, but it is a genuinely lovely road-going supersport bike.
