As a substitute for the exhaust gasket on most gas powered bikes ...
For the intended application it seems fine - a little rough. For the gas bike application - besides having to drill out and expand the holes - I'm questioning the need in the first place. The problem is more in the mounting flange and hardware than in the solid fiber gaskets. Take a minute to ensure the flange is flat and dress carefully on the flat side of a wheel if needed. The bolts must be grade 10.9 - if they look cheesy - don't use them. Get, and/or cut and dress some better. DO NOT use thread sealer (not even high-temp.) And DO check and retighten 3X after riding. Finally be prepared to repair the threads in the head - which are very soft. That's not a beginner task.

makes a good motorized bike part
perfect fit for the 66cc motorized bike kits you can find and unlike the cheapo junk one that came with it this one actually does a good job does fit a bit snug as the bolt holes are a little wide but works excellent
