'Trezzi Clubman' dual sports seat (black) with METAL base. This seat is the same as the old Giuliari 'Ancillotti' seats ofrm the 70's and 80's. It is unique in that is has a pressed metal seat base and is super-strong.

Following examples provided by us here at RLC, Trezzi has slighlty 'lipped' the back edge of the seat so that it doesn't touch the scooters frame & paintwork, which was always a big defect of the original seats back in the day. These really are spot on. 
Supplied complete with rear closure cracket.

Does the under-seat airscoop need to be removed for fitment of the seat? : No

Is the rear closure catch included? : Yes
