The Yamaha XT660R has an overall MOT pass rate of 88.3% across 5,095 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 Yamaha XT660R are brake pad(s) less than 1.5 mm thick (41 recorded failures), shock absorber seal failed and leaking oil (38), and tyre tread depth is below minimum requirements of 1.0mm (31). 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.
On the safety side, the most frequently flagged dangerous fault is brake pad(s) less than 1.0 mm thick. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Yamaha XT660R with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
A typical Yamaha XT660R owner drives around 819 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 Yamaha XT660R models stay on UK roads for around 22 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.
