Watch out Vespa--there's a MADASS out there!

[Spidey]

It's a standard Chinese-made dirt bike engine (I think the one used in most Hondas).  There's a 125, 138 and 170 something upgrade kit for it.  The kit can also gives you a manual transmission.  Woot! 

I don't think they're CA legal b/c of emissions.  When I was looking at them last year, there was one place down in the Inland Empire who carried them, but they still weren't street legal for CA.  Mebbe that's changed since then.
