It is interesting to learn how the new XXL-size  Leitra  fairing has come about. The plug for the ordinary- sized body is made of foam core with hard glassfibre- reinforced plastic surface, which has been carefully shaped up, sanded down and polished (beyond call of duty) to allow it being used as the model for the mould, i.e. the negative  forms (observe the plural) from which ultimately the thin- wall fairing parts are made.
    Because no small- size producer, like the  Leitra  could justify the cost of developing differently- sized models for different- size fairings, Rasmussen and Fuchs chose a novel, yet practical method to achieve the result by recycling [sic!] the existing body plug. Simply put, because master moulds for the fits- everybody- but- Fuchs-  size were done already years ago, and can be expected to last "forever", they elected to cut the plug up in specific places, rearrange the parts to the new size, "fill in the cracks" with foam, and plast them over to make a new oversize plug from which new moulds could be taken.
    In this fashion the body would become around 20-cm higher at its highest point (10 cm higher at the base of the windshield), and the inside volume would became that much roomier (that much to the power of 3 acc. to the unimpeachable laws of Euclidean stereometry). Observe the marks at the gap used to align the disjoined parts in the initial stages of remodeling. Also note the apparent ease with which Andreas is able to sit, smile and simultaneoulsy greet the camera with the roof of the cut- off fairing as were it mere chapeau !
    Begun in 1995 and finished a year later, the new fairing is already a reality, and has since caused many a Swiss burgher  to choke on their  Big Macs mit Extra Schmaltz  in response to that . . .  thing, that, that Spitfire  without wings or propeller approaching at high speed at ground level in Bern, Switzerland, and thereabouts.
