Velo has an engine problem, which is the piston, that's all I know. I'm clearing my conscience. I'm selling it as is, if you're interested, welcome. The sale is easy, I'm in a hurry. If you're serious, we won't disagree. The price of the piston is 650 in Boursport. Labor costs vary from place to place. The mileage of the bike is 3500. (With customs paper) You can get a license plate for it.
