I have now bought this product for the second time as the piston was damaged after a short period of use. In contrast to the first delivery, the piston was pre-assembled with rings and the upper piston rings are now clearly different, as they should be. The first delivery came with two identical copper-colored piston rings, which probably caused the damage. In terms of quality, everything is clean and fits perfectly. However, the bore in the motor housing needs to be adjusted. (Only for professionals) The set provides significantly more power but no increase in speed.

The price/quality ratio is good for recreational use ... Of course, in the case of the Honda Transalp valve adjustment tool, a small modification has to be made to the tool itself, i.e. an anatomically correct bend in the wrench stem is easy to make yourself due to the soft material, so it is better suited for use from the service hatch, no need to remove the valve covers from the body, but can be used for the valve adjustment "service props".

Honda VT600C, the wrench is made of good steel, the "squares" cut in it perfectly fit the valve adjustment screws, 3x3 and 4x4 mm - most motorcycles have just such screws. This is an indispensable tool for someone who services his unicycle himself. Thanks to the fact that it is quite long and thin - it allows very precise adjustment of valve clearances, no more pliers!

I am in possession of a Yamaha 250 x max. The wrench - variator lock, which I purchased from WAS, is of the highest quality, designed for my motorcycle, made with special sensitivity to quality and aesthetics.

The cylinder came without any damage/defects. The installation went through without any problems and has been riding in the Cygnus for a very long time! I heartily recommend.
