I bought the bushings for a 2005 Yamaha Aerox 50, a friend advised me to buy a Chinese replacement-just an engine bushing and they should be universal. I bought and they did not fit. For a long time I was looking for suitable replacements, and the dimensions did not match, and they matched, but quickly wore out, and finally I came across the bushings offered by Gmoto, and I found 100% match to the description. They fit like the original ones, there were and are no problems with them, finally in my Joasia there is no play on the engine suspension! I did not mention the shipping, as its history was very short. I give a positive review of both the product and the store.
The bushing fits perfectly into the suspension rubber of the Simson S51 engine. I wasn't sure if I was buying right because the description is modest, but yes, that's exactly what I had in mind. What would be useful in the description would be its inside or outside diameter.
