I'm going to speculate that you would get the brake lever that you need - I believe that the gloss black in the description is an error.
When making an emergency/touring parts kit for my Downtown 300 I ordered some levers and it had the same part number for the brake lever with the gloss black mentioned in the description - when it arrived it was the correct "bare aluminum looking" color. (As a disclaimer I should probably state to contact Stadium or your local dealer to verify the color first
)
Urbestfriend: In the parts listings when you see the NH045MA, NH124MA, etc those are the paint color codes for the body panels (ie paint code to give your autobody shop to mix some matching paint). The 3-character codes (in brackets) in the table below are the associated Kymco color codes suffix which are appended to the part number when the dealer orders a body panel from Kymco. For example if a body piece has a part number of 12345, if they needed it in Bright Silver they would order a 12345-N8P. So in a parts listing if you see a part reference with either NH045MA or N8P it would be Bright Silver, etc..
NH045MA Bright Silver (N8P)
NH124MA Dark Gray Metallic (NFP)
PB107MA Bright Blue (BAP)
YR168PA Orange (YFP)
PB244MA Deep Blue (C6P)
In the parts listing for an '06 Xciting 250 all of the body colors above use the same color of brake lever, color code suffix M3A.
Don't know if any of this was useful to you but thought I'd type for a while anyway...
