Now a days some people find it hard to find spares for their Jawa mopeds. However, there is a website that sells spares for Jawa mopeds, and they seem to have a good stock of items with plenty of spares and replacement parts. All the Jawa moped spares are listed as Babetta spares since that was the name for them in some eastern bloc countries, but the names remain the same. E.g: Babetta 210 = Jawa 210

Pricing is decent and shipping times to the UK are good. I don't know how long it would take to ship to the USA.
