T5

Jump to: navigation, search

The Vespa T5 is based on the P-series body, but with a large rectangular headset(complete with fuel gauge and tachometer), further sloped horncast, extended angled-off tail end, and a front spoiler.

The engine contains a 125cc top end, but with aggressive porting to give speeds in excess of 70mph. Later variations such as the T5 Classic and T5 Millenium had the same body design as the later model PX series, but contained the 5 port 125cc engine (not to be confused with the alleged 5 port 150cc engine found in the Stella, the two are quite different and top ends are not interchangeable between them).
