Here's my review and trail ride of my Sherco 300 SEF 2021 model dirbike, I ride her every couple of months when four stroke fever gets to me. I've always loved the KBS valving on the Sherco forks, I find her the most reliable four stroke around, I've owned several motocross four strokes which don't come close to the reliability of this machine. Obviously comparing Enduro machines to MX machines isn't quite fair, but it gives you an idea. If you are riding enduro then the hours you put on the engine usually translates to longevity, after 100 hours of riding this bike, I've changed clutch plates, oil and filters. She runs as good today as she did the day I got her. No spluttering, no backfiring, revving as strongly as I can manage her. I've added a Sherco Low seat and lowering link to her, she's still a bit tall for my height, 5 foot 8, I only weigh 170 pounds. Besides stalling more than a 2 stroke does, she makes my heart happy every time I throw my leg over her.
