This 1997 Yamaha XJ 600 S Diversion has a 28.7% first-time MOT pass rate—dramatically below the UK average of 80%—which signals serious reliability concerns for a motorcycle now 27 years old. The good news is that dangerous defects are rare at 2.1%, so catastrophic safety failures aren't the primary issue; instead, expect persistent wear-related failures in brakes, lights, and exhaust systems typical of ageing bikes.

At a median mileage of 26,926 miles, these machines have been ridden relatively gently, yet they still rack up an average of 0.28 failures and 0.9 advisories per test, suggesting the Diversion's age is catching up with mechanicals faster than low mileage alone would explain. Before buying, budget for a full pre-purchase inspection by a motorcycle specialist—don't rely on MOT history—and factor in £500–£1,000 for essential remedial work.
