I think Tino does one like that also. Pictured in Stickys book.
The SSC one looks pretty trick but for $671 it's a bit high.
If you really want to cut some holes in a hub my guy can do it or I'd hit up Deanspeed or HotRodAl.
I have a pm tuning disc brake. "Pepper pot" style (pictured). I am interested in cutting 4 or 5 holes in the rear hub maybe 1 inch round to give a similar look. Nobody does this, so I'm guessing their is a good reason. How unsafe is it? I have only seen this done on an older custom scoot from the west coast built by N. Shafhouser (sp?) from hardpack s.c (pictured). Because it is a custom, it might be for looks and if ridden, swapped out for a solid hub. The only alternative is from Siagon Scooter Center (pictured)
What silver? Special? Late SX/early-mid GP/dl, Luna? Late GP/dl? They're all significantly different. For Luna/late SX/early-mid GP/dl then Toyota silver sky metallic 1D6 with a semi-gloss clear coat is pretty close, although a little too metallic.
For something just vaguely close to Luna/late SX/early-mid GP/dl then Porsche M7Z 'GT sports silver'.
