New-Ray, which is a Chinese company, makes some wonderful 1/32 scale motorcycles, scooters and quads (in fact the Schuco ones could be made by New-Ray) and rhese are rather inexpensive. I purchased the set of Ducattis. They also make Vespas, Hondas, Suzuki and possibly Yamahas. They are not easy to locate. I hate to say it but the best place to find these is probably eBay.
