Should I check the MOT history before buying a 2015 Sinnis Xf?

The 2015 SINNIS XF falls short of the UK average with a 75.9% first-time pass rate against 80%, and over one in five of these bikes have recorded dangerous defects—a significant concern for a used buyer. This isn't a robust performer on the MOT, and you need to factor in extra inspection time before purchase.

With a median mileage of just 6,045 miles for a nine-year-old bike, these machines are lightly used, yet they still average 1.27 failures and 3.5 advisories per test. Get a pre-purchase inspection from a specialist familiar with Chinese-market scooters, because the failure rate suggests maintenance shortcuts or design weaknesses that a routine dealer check won't always catch.

We have limited data for the 2015 Sinnis Xf — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

What tends to go wrong

Across 161 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Lighting 28.7%

Drive chain slightly loose · Rear reflector missing · Rear Stop lamp not working · …

Usually cheap to fix. Worth confirming all lights work before collecting.

Other issues 21.7%

Drive chain worn but not considered excessive · Chain guard missing

Tyre wear 16.8%

Rear Tyre worn close to the legal limit

Exhaust & emissions 14.3%

Exhaust noisy

Suspension & steering 11.5%

Rear Wheel bearing has slight play · Steering headbearing slightly stiff or notchy

Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.

Brake wear 9.4%

Front Brake pad(s) close to minimum limit · Front Brake lever is short but brake can still be readily applied

Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
