I will post it for the first time.
I found 888 SPS in the auction in Japan. Do you think this is a real SPS?

The fuel line from the fuel tank is the same as SPS. Silencer is also similar. The position of the stem shaft on the yoke also looks like SPS.
The mileage is only 13519 km. The current price is about 13k (tax included).
