2022 Yamaha YZF R7 (YZF690) 0.7L Petrol · HG22 EGC

The YAMAHA YZF R7 (YZF690) has been plagued by recurring exhaust noise advisories since its first MOT in May 2025, indicating a potential issue with the engine or exhaust system. Despite two consecutive passes with the same advisory, the most recent test in May 2026 showed a single advisory for exhaust noise, suggesting some improvement but still leaving room for concern. The failing record in May 2025 highlighted issues with the rear tyre tread depth and a loose drive chain, which could indicate mechanical wear and potential safety concerns. Given the low mileage of 23,899 miles at 5,975 miles per year, this appears unusually low for the vehicle's age, potentially reflecting light use or long periods of inactivity. However, the rapid decline in mileage between the 2025 and 2026 tests suggests a sudden increase in usage, which may have exacerbated existing issues or led to new problems. In terms of mechanical guidance, the exhaust noise advisories point to possible issues with the engine or exhaust system, which should be checked during a test drive. Listen for any unusual sounds when accelerating or braking, especially under load. The loose drive chain in 2025 could indicate wear on the transmission or drive components, leading to vibrations or jerks during acceleration. Feel for any unusual resistance or binding in the steering, which might suggest worn suspension linkages or bushings. Additionally, inspect the rear tyre tread depth, ensuring it meets the legal minimum of 1.0mm, as noted in the advisory. These checks will help identify any immediate issues that need attention.
