Great service and great products. Steve and Stacy went above and beyond for me!

Max Stewart

Steve is awesome! Super knowledgeable, always willing to help and gives great suggestions/advice.Product is amazing. I’ve got the tuned ECU and the medium comp head.Steve helped with getting the cylinder re-nikasiled on my first rebuilder with piston A, then my most recent he supplied me with Piston size B.I’ll send it back in for Nikasil and another size A piston on the next rebuild.He even threw in an extra O-ring since I damaged the first one my reinstall.Will continue to purchase my rebuild kits through SB Moto.

My 2023 Husky 150TPI bogged under the pipe unless I abused the clutch. When it did hit the power band, it was like all or nothing. I really didn't enjoy riding it. Steve really helped me understand how the ECU re-map and head would help. It was super easy to install (and I'm more of a YouTube mechanic). The bike runs super smooth now. much more linear through the power band and doesn't bog. It has a lot more torque in the low end as well. I wish I would have done this last year!

ALL I can say is I actually LIKE riding my 2025 KTM SX 300 now. WHAT a difference, it runs clean, efficient, throttle response is back to what I expect, and it is FAST. Sorry for the capital letters, I am just super pumped and excited that my bike runs the way it is supposed to. Thanks a million South Bay Performance, and thanks for the One day turnaround!!!!!! A+++++

I haven’t had a chance to install yet, but the service and support I’ve gotten before even buying, the hand signed thank you in the box, and the email after ordering thanking me for purchasing from them, shows this is a company I want to support. Can’t wait to see how the actual product works!
