    The protection is a little too thick and I had to grind it slightly to make it go into the bike on the shaft otherwise all ok.

    The product is really high quality, it holds the sprocket very well, the play is negligible, the material looks solid. Greetings

    The safety device fits the 139FMB gearbox mounted on the Junak 902. It seems to be of good quality, but as is usually the case - "will come out in the wash".

    I own a cross with a 152fmh Loncin 110 engine I needed to protect the sprocket this protection fits perfectly it is well made, the holes are the right distance and the right diameter. The milling inside is well fitted so there is no play. The protection is thick which stiffens the mount. I recommend because the product is of good quality.
