So,that's how it looks,at first view you would'nt recognize this Bike as a total-rebuilt,maybe    somehow similar to the SBK-Bikes,where only the stickers are identical with that stuff you can buy.
You may notice it (or not),the first the first enlarged underseat-fueltank is mounted,with nearly stock capacity.

to estimate the weights:

The Seat (Carbon/Kevlar),incl. Seatpad: ~  880 gr (1.9lbs)
The Carbon Subframe :560 gr (1.2 lbs)
The # -Plate bracket: 90gr ( 0.2 lbs)

That adds up to 3.3 lbs all in all,only the stock Subframe is about 4.8 lbs,not counted the underplastic ,Seatpad,Tailsection + Cover.

A Test,the Tailsection + my Carbon Subframe suits to a std.Fueltank too.     RC51 std Fueltank+ my Tailsection.JPG (143334 Byte)
