Since this is an all new motor for Sherco, they put a lot of cool new features. The first is that it has an electronically controlled, drum valve exhaust valve system. Instead of the standard power valve that is mechanically driven and is a sliding door essentially. the Sherco’s design is a rotating drum that, according to them, has better sealing, more precise actuation, less prone to sticking, and is electronically controlled by the ECU. In practical terms, this translates into smoother, broader spread of usable power, which is exactly what you need from a 125 off-road machine. On the testing loop, when we rolled on the throttle it was apparent that it was a 125, but it deffinitly wasn’t as mellow as some other 125 off-road bikes that we’ve tested in the recent years. And the best part was that the power was extremely linear – we weren’t falling on our faces then having to clutch it to get back to the meat. You still have to use the clutch more than any other bike in the range but it wasn’t as necessary as we initially thought.
