2022 KTM 50 SX. Just had the top end rebuilt 3 months ago. I should be able to find the receipt for it! Straight line Motorsports is who has been taking care of the bike for us. They are a KTM certified shop. They did the top end work as well. It has a brand new chain, new rear sprocket, new drive sprocket, and we just adjusted the valve lash after last race. Has a brand new rear tire and comes with an Extra set of tires and rims for the track just in case you blow a tire or something. This bike has won two championships!!!! Runs absolutely amazing!! Most 50s are hard to start and give you constant problems, but this dude has been a tank!! I can show you how to start it with literally two kicks on a freezing cold day!! This 50 is very solid and dependable!!
