2021 Triumph Street Triple RS 0.8L Petrol · GU21 ACJ

The most recent DVSA MOT test, conducted on 2 April 2026, resulted in a clean pass with no defects or advisories recorded, continuing an unbroken pattern of straightforward approvals across the three documented tests. With no advisory notes on any of the examinations and no recorded failure points or recurring component concerns, the available MOT history presents a stable and well-maintained picture from a statutory roadworthiness perspective. While a clean MOT record is reassuring, it is worth noting that motorcycles of this type often pass MOT testing with minimal scrutiny on items such as brake pad wear progression, suspension damping performance, or minor fluid leaks, so the absence of advisories should be regarded as a baseline rather than a complete mechanical endorsement. The recorded mileage of 4,995 miles over approximately five years equates to an average annual usage of around 999 miles, which is exceptionally low for a performance motorcycle of this class and places this example firmly in the low-mileage, lightly-used category. Such restrained usage typically indicates either occasional weekend riding, primarily fair-weather use, or extended periods of storage, and it carries its own set of mechanical considerations quite distinct from those associated with high-mileage examples. The relatively even mileage progression suggested by consecutive annual MOT tests implies the machine has been in regular but limited use, reducing the likelihood of long-term standing-related complications but still warranting attention to age-related deterioration of consumables and rubber components. Given the low annual mileage and the vehicle's age, a prospective buyer should place particular focus on time-sensitive degradation rather than wear-based wear items. Tyres should be inspected closely for sidewall perishing, cracking, or ozone damage, as rubber compounds deteriorate with calendar age regardless of tread depth, and an unused or barely used tyre can still present a safety hazard if it has hardened. The 12-volt battery should be load-tested, as prolonged periods of inactivity are highly detrimental to lithium and lead-acid battery longevity, and a borderline battery may pass an MOT functional check yet fail under real-world starting loads. Brake calipers, particularly the front radial-mount items typical of this model, should be examined for seizing or piston stiction from infrequent operation, which can manifest as uneven pad wear, a spongy lever feel, or the motorcycle pulling to one side under braking. Discs should be checked for surface corrosion, pitting, or lipping, and the hand and foot controls should operate smoothly without binding. Equally important is a thorough review of fluid servicing and drivetrain condition, as these are governed by time rather than mileage. Brake fluid should be flushed and renewed regardless of the odometer reading, as hygroscopic absorption of moisture reduces boiling point over time and can lead to brake fade under spirited riding. Coolant, fork oil, and any hydraulic clutch fluid should likewise be considered due for renewal on an age-based schedule. The drive chain and sprockets, even with low mileage, can develop surface corrosion from damp storage or infrequent lubrication, so the chain should be inspected for stiff links, rust, and adequate tension, with the sprocket teeth examined for hooked or shark-fin profiles. A careful cold start should be observed for any irregular idling, smoke from the exhaust, or warning lights on the instrument cluster, and a test ride should be used to listen for suspension clonks over uneven surfaces, verify smooth throttle response, and confirm that the quickshifter and electronic rider aids function as intended. Finally, verifying the service book stamps, Triumph dealer or specialist maintenance history, and the presence of any outstanding recall or warranty work will provide further confidence in what is otherwise a very clean and lightly-used example.
