There ok
ive got one one my gp... only a few of issues.....
...they seem slightly to long so if you dont turn the front wheel in the right direction it can fall over
...When your riding along it can vibrate down

can be a bit alarming going up a dual carriage way doing 70 and sparks coming from the stand
Apart from that there great
Ideally a lambretta side stand should be on the other (right ) side Were the weight is.
They are quite well made though. just need a little fetteling as most things lambretta

When i was young my Mom said "if you haven't got anything nice to say, say nothing at all " ..................... and people wonder why I'm quiet around them !
