The picture
Across 1,332 MOT tests, the Lxr 125 Sy 125-10 returns 68.5% first-time pass — well below the UK fleet average. The single most-logged Major fail is headlamp aim out of spec. A non-functioning shock absorber and a missing rear reflector round out the top three. Average tested mileage sits at 7,217, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 8.2-point gap between bands means the year you buy Lexmoto Lxr 125 SY 125 10 has a real effect on what turns up at the garage.
Best band to buy
68.8%
2018–2020 registration
the 2018–2020 band climbs to 68.8% — a 8.2-point improvement. Failures here are mostly wear items: too low, has a serious fluid leak — the structural issues that drag down older examples don't appear in the top-10 for this band.
Band to be cautious about
60.6%
2021+ registration
On the 2021-on band, the data shows a 60.6% pass rate against a fleet average of 68.8% on the newer band. The main culprits logged at test: too low, excessively stiff or notchy, and not working. Average mileage on test for this band is 6,685 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2018-2020 (68.8% first-time pass). Worst band to avoid: 2021+ (60.6% pass). That's a 8.2-point spread across 188 older tests and 1,693 newer ones — year of build makes a material difference on this model.
