The massive rise in sales of cheap mini bikes labelled, (MUPPs) Motorcycle Used in Public Places has resulted in significant savings for customers looking to buy quality motorcycles for their children. According to estimates by the Motorcycle Industry Association, sales of cheap imported mini bikes rose from around 7,000 in 2001 to 70,000 in 2004. This has had a devastating impact on sales of high quality machines from established European and Japanese manufacturers and as a result prices have tumbled by up to 50%.
