Wal’s Lambretta S1 Quattrini 210 Came in for a dyno just to set up the Avanti Ex-Box ST he had just fitted 😁 / sgengineeringservices #vlog #vespa #lambretta #scootering #2stroke
The only other box exhaust I’ve tried on a Quattrini was a chisel speed box and that was 2 hp more but it was on a brand new build this one has a few thousand miles on it.
Magic Stuart, love my quattrini, its my fav out of the rb20, ts1 245 and the quat
Love how we all hide on the rhs 😂😂
The a beautiful s1
Sydney didn’t make a appearance
How does the Ex box St compare to other box exhausts on that kit ?
