Factors affecting top speed:
* Engine condition: A well-maintained engine will perform better.
* Rider weight and gear: Heavier riders and extra luggage will affect speed.
* Wind conditions: Headwinds will slow you down, tailwinds will increase speed.
* Road surface: Smooth surfaces allow for higher speeds.
* Tire pressure: Proper tire pressure affects performance.
To find the top speed:
* Consult the owner's manual: This is the most reliable source.
* Search online: Look for Yamaha Vino 125 forums or reviews.
* Contact a Yamaha dealer: They can provide specific information.
Remember that manufacturer-stated top speeds are usually theoretical and may not be achievable in real-world conditions.
