The 2001 Yamaha TW125 has a first-time pass rate of 78.7%, just below the UK average of 80%, suggesting fairly typical reliability for a two-decade-old bike. The 16.1% of vehicles that have ever had a dangerous defect is worth noting if you're buying one without a full service history—it's a reminder to inspect brakes and steering carefully before purchase.

These bikes are running at sensible mileage for their age, with a median of just over 11,000 miles, yet they're still racking up nearly two failures and five advisories per MOT on average, pointing to wear items like exhausts, chains, and lights rather than catastrophic engine problems. Get a pre-purchase inspection focused on consumables and electrics, and budget for regular maintenance to keep one of these reliable.

We have limited data for the 2001 Yamaha Tw125 — treat the figures below as indicative rather than definitive.

⚠️ Around 1 in 8 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 217 vehicles — figures show how many had each issue flagged at least once in their MOT history.

Lighting 45.6%
Drive chain slightly loose · Rear Drive chain sprocket slightly worn · Rear reflector on motorcycle missing · …
Usually cheap to fix. Worth confirming all lights work before collecting.
Other issues 39.9%
Drive chain worn but not considered excessive · Drive chain excessively loose
Tyre wear 38.2%
Front Tyre worn close to the legal limit · Rear Tyre worn close to the legal limit
Budget for a full set — on a vehicle this age, tyres are expected consumables. An inspection will confirm how much is left.
Suspension & steering 32.5%
Steering headbearing has slight free play · Rear suspension bush has slight free play · Steering headbearing has excessive free play
Harder to spot without a ramp — this is a good reason to book a pre-purchase inspection.
Brake wear 23%
Front Brake pad(s) close to minimum limit · Front Brake disc(s) slightly worn · Front Brake pad(s) less than 1.5 mm thick
Ask the seller when brakes were last serviced. If they don't know, factor in the cost.
Exhaust & emissions 12.7%
Exhaust is leaking but is not excessively noisey · Exhaust noisy
