2021 Kawasaki ZR 900 FLF 0.9L Petrol · DB21 CZE

A pattern of intermittent safety‑related failures underpins this bike’s MOT history: the most recent test in August 2026 recorded a pass but flagged a noisy exhaust and, separately, a failure for a missing rear reflector, while earlier examinations revealed a major front‑brake effort fluctuation in July 2024 and a slightly stiff steering head bearing later that year. The record shows a mix of advisory‑only outcomes and outright failures, suggesting that while the motorcycle can meet the basic roadworthiness criteria, specific components have required attention at different times. With 17,689 miles logged over roughly five years, the average annual distance is about 3,500 miles, which is low for a 2021 model. The MOT dates – mid‑2024, mid‑2025 and mid‑2026 – indicate regular testing without significant gaps, implying the bike has not been subject to prolonged storage periods that could hide latent corrosion or battery issues. Low mileage generally reduces cumulative wear on consumables such as brake pads, tyres and suspension bushings, but it also means that any wear that does exist may be concentrated in specific areas highlighted by the MOT failures rather than being uniformly distributed. When inspecting the exhaust system, listen for a persistent rattling or hissing that could indicate a cracked pipe, loose mounting, or deteriorated muffler baffles, all of which could be the source of the advisory noise. Verify that the rear reflector is present, correctly mounted and unobstructed; its absence not only caused the recent failure but also compromises visibility to other road users, especially in low‑light conditions. A quick visual check for corrosion or cracked brackets around the reflector mount will help confirm that the issue has been remedied. The front‑brake fluctuation noted in 2024 warrants a thorough pedal feel test: the brake lever should apply smoothly without a pronounced pulsation or sudden change in effort, and the front disc should be free of warping, scoring or excessive pad wear. On a ride, monitor for any pulling or uneven braking response, which could signal a sticking caliper or hydraulic inconsistency. The advisory about a slightly stiff steering head bearing should be assessed by rotating the handlebars slowly; any notchy resistance or grinding feel may indicate bearing wear that could develop into a safety concern if not addressed. Checking for play in the steering column and ensuring smooth, quiet operation will confirm whether the issue has been resolved since the last advisory.
