Well done for putting such a great effort into restoring your Vespa, even if she is a 'rollscanardaly' lol. A good picture of an Arriba can be found at http://www.motorini.com.au/index2.html The one in the picture is a 125cc but the 49cc looks exactly the same, just a less powerful engine.
Cloe's colour is 'Silver Mist' but you'll get a good idea of what she looks like. It's soooo rainy here today and Chloe and I can't go for a ride! :o( lol But she's such a good girl - refuses to take more than $4.50 worth of premium unleaded petrol! Where do you ride on your Vespa?
