Sherco STR Problems - Resolved!! – Flat Battery, Slipping Clutch & Engine Running Backwards

If you’re looking to buy a Sherco STR 300 or you already own one and are experiencing issues, this video is a full honest review of the problems I’ve had since purchasing my 2024 Sherco STR 300 brand new.

In this video, I cover three major issues that have repeatedly affected the bike:
🔋 Flat battery / starting issues
🧴 Slipping clutch & dragging clutch problems
🔄 Engine running backwards (yes… actually backwards!)

I’ve replaced multiple parts including the ECU, coil, regulator/rectifier, spark plug, and more — and I still continue to face the same issues. This video is for anyone who wants real-world ownership feedback, not marketing hype.
Whether you're a trials rider, researching the Sherco STR, or comparing it against GasGas, Beta, TRS, Vertigo or Scorpa, this honest breakdown will help you make a more informed decision.
