Vespa KDX Broadford Track Day

Best viewed with "watch in high quality" enabled (bottom right of vid). Vespa KDX Broadford Track Day. The scooter is now almost complete and we spent the day testing it out at Broadford. Unfortunately the top straight is up hill and into a headwind. The bottom straight was not long enough to get into 4th, however we rev'd it out to 10,000+rpm in 3rd which is 140+ Km/hr (Stop speed not top speed). The Vespa was really stable and reliable. It handled so well I actually passed a GSX-R on a corner. Next stage is dynoing the bike and setting up an expansion chamber to suit (yes, we aren't even running a good pipe!). It looks like will hit our target of 108 miles per hour (175 Km/hr).
