This flywheel weight will fit on the Sherco trial bike. The flywheel weight changes the power delivery making the bike smoother and more controllable off the bottom. It will help the bike grip better and help prevent stalling. It also comes with an ignition cover spacer, gasket, and longer ignition cover bolts. For models 2012 and up.
First off, was easier to install than I thought. Use loctite. Only took about 15 minutes and I can tell the difference, I feel more control.
Definitely helps with stalling on my 18 ST250 factory, smoothed the bottom end out a little at take off, which is where i would stall some times (similar to what others have said). Fairly easy to fit. I pressed the inserts in as they are tight and didn't want to use a punch.
I put this on my 300 Sherco Factory it made a big difference in power delivery. smoothed it out made it crawel without stalling Makes it a lot more forgiving for a nov. trials rider
I wanted to tame the off-idle power of my '12 Sherco 290 and smooth the delivery. The S3 flywheel weight did just that! The motor will crawl along at low rpm giving the bike good grip in the mud without stalling and still has enough "hit" to clear an obstacle. Really transformed the bike. Well-made and the installation was straightforward.
