Bud Racing Factory Pipe In good condition. - Developed by Bud Racing and made by HGS, the supplier of the best Euro teams. - This expansion promises greater recovery at low revs (eliminating engine gaps) and power gain over the entire engine rev/rpm range. - Each pipe is developed based on the weaknesses of each bike in order to fill the gaps in the standard exhaust. Came off of a 2017 KTM 125 SX. I believe this will fit the models listed below but please do your own research and confirm fitment before purchasing.
