Check a specific BMW R90SShould you buy a used BMW R90S?
The BMW R90S has an overall MOT pass rate of 90.9% across 1,459 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the BMW R90S are headlamp at least one does not illuminate on dipped beam (7 recorded failures), steering headbearing has excessive free play (5), and direction indicator not working (4). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical BMW R90S owner drives around 344 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most BMW R90S models stay on UK roads for around 52 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
