Gilera Argentina split from head Italian office in the begging ‘80s, they continue making “Italian” designed 4 strokes bikes till ’81 or ‘82 then a new design with Hiro (Italians) engines and from there till this new century they only produce 50cc moped, these days as most factory all around the world the buy in china and only assemble here few parts... they “legally” keep the name for Argentina, so they ask Chinese to send it with that name.
I still keep my ’77 200cc Gilera, my first “real” bike!!!
The SMX400 is a China Bike (the engine too), not an Italian Gilera and not an Argentinean too, I don’t have personal experience about these bikes but friends in common of users have told me that all bolts and nuts comes loose or get loose very fast, if you tide them nothing will absorb the vibrations (sic)
, fork oil seal leak in just few kilometres if they dont forget to put that in, and I know a case with less than 1000kms where the key woodruff from the crankshaft to the alternator cuts and left the pour rider at the middle of nowhere to be towed by a .... BMW
To complete: less than 30HP, 190Kgs, cast wheels and front in 17 inches ....
