Should I check the MOT history before buying a 2004 BMW R850?

The 2004 BMW R850 is substantially more reliable than average, with a first-time MOT pass rate of 90.2% against the UK average of 80%—a meaningful ten-point advantage that suggests these bikes have been well-maintained by their owners. However, 16.1% have recorded a dangerous defect at some point, which is worth noting if you're planning longer journeys or rely heavily on the bike.

At an average mileage of 22,828 miles, these are relatively low-mileage machines for their age, indicating light use or careful ownership. The typical bike returns 1.58 failures and 4.0 advisories per test, suggesting minor wear items rather than structural problems—so budget for consumables like brakes and cables, but don't expect major engine work when you buy one.
