2025 KTM 125 SX for Sale at Ultimate KTM Gold Coast in Biggera Waters, QLD | Specifications and Review Information
2025 KTM 125 SX
There are very few sounds that can't be beaten. The crack of a soda can on a blistering hot day. The ping of the perfectly executed golf shot. And the scream of a 125 cc 2-stroke charging down a long straightaway. The 2025 KTM 125 SX takes its leads directly from the Factory Racing team and puts them to work like nothing else. Like the sound it makes, it cannot be beaten.
This motorcycle is designed, developed and produced in Austria.
