About this model
About the Sym ADX 125
The SYM ADX 125 is an adventure-inspired maxi-scooter powered by a liquid-cooled single-cylinder 125 cc four-stroke engine. Its elevated riding position, larger wheels and rugged bodywork set it apart from conventional urban scooters. The ADX line was introduced to meet growing demand for versatile scooters that perform well in urban environments and on light off-road terrain.
The ADX 125 is ideal for A1-licence holders who want more versatility without the complexity of a full motorcycle. The larger wheels, longer-travel suspension and raised riding position make it more comfortable on rough surfaces than a standard city scooter. In town, the automatic transmission and practical storage capacity add convenience. It competes with the Honda ADV 150, Yamaha NMAX 125 and Kymco AK 125 in the adventure-scooter segment.

Before you buy
What to check before buying
- Check the variator (drive belt and rollers) for premature wear; aggressive urban use accelerates this service interval.
- Inspect the larger wheels and rims for damage from off-road use or kerb strikes.
- Check the liquid cooling system for leaks at hoses and the radiator to prevent overheating issues.
- Examine the ABS sensor (if equipped) for dirt and damage; an off-road riding style can affect sensor performance.
- Check the battery condition; the liquid-cooled engine and additional electronics draw more than simpler scooters.
