One of our own bikes, a 2005 PX150, 2-stroke 150cc, 4-speed trans, disc brakes.
Found this in the Vespa warehouse, had to have it, it was still brand new. They only brought in a handful of these in 2005 into the USA, as 2-strokes bigger than 50cc are normally not allowed in the USA. It originally came with a catalyzer in the pipe, we put on a performance pipe and rejetted.
Spare tire on the left side, electric start, auto-mix on the oil system. Great scooter, all metal bodywork, I love it.
