Hi. I´m just to buy a Gilera Runner 50Sp for my son. I´ve found 2 bikes that are for sale. One of them is a 2007 model witch have run just 60km and look as new. The other one is a 2011 model and have run 560 km, also looks as new. Before I buy one of them I wounder if anybody could tell whats the difference between these two models, I´m thinking about spesifications and quality.
