This Boyesen Rad Valve RAD42E was going to be for my 2019 KTM SX 250 / 300. I have since sold the bike and am selling this like new Boyesen Rad Valve intake Reed Block. UPDATE: This was ONLY Installed and then taken off, So it is virtually brand new, never started on the bike. I Had a large 5.6kg shock spring that then touched the intake boot when using this Rad Valve. I had to go back to stock, SO, if you have a smaller than 5.0kg shock spring, it will fit and work perfectly!!!!! Get a New Boyesen Rad Valve for your KTM, Gas Gas, or Husky for HALF of new!!!!!! HURRY, not lowering again. This Rad Valve should fit KTM SX /XC and Husqvarna Husky TC / TX 125, 150, 250, and 300's but please check fitment. I ordered a set of new OEM Boyesen hose clamps and will include with this. Only one is pictured in my listing but this will come with everything needed to install in your motocross bike. I have used Boyesen Rad Valves on all of my CR 250's and 500's, they are awesome!! Original Box and gaskets and clamps are included. Enjoy! New Boyesen Clamps are here!!!! and will be included (both stock OEM Boyesen clamps are included). I have tons of KTM parts for sale and would love to make room for more parts in the garage. Thanks for looking and Happy Holidays!!!
