2-speed set SL6 XLI (SER804367)

For the Serpent 748, Michael Salven also designed a lighter gearbox, to achieve lower inertia. Xli, for eXtra Low Interia. The adaptor, shoes and bell are also reduced in size and thus have lower mass, which gives better acceleration overall. The well proven 2-speed gears remain the same as before.
Current 748 Natrix and 747 racers can easily upgrade to this new Xli SL6 gearbox.
