rs_geeko 1 of 1 Custom Built Aprilia RS660. British Racing Green. TT livery. A 659cc parallel-twin that has actually competed on the Mountain Course in the Lightweight class since 2021, making the tribute more than purely cosmetic. The RS660 produces 100 horsepower from 169kg dry — a power to weight ratio that makes it genuinely rapid despite sitting well below litre class displacement. On the right road it is the kind of machine that makes larger bikes feel unnecessarily complicated. Whoever built this understood exactly what they were doing with the colour choice. The Mountain Course has claimed some of the most iconic green machines in motorsport history. This one will never race there but looks like it belongs there anyway. Would you build a TT tribute livery on your own bike? [ Media: rs_geeko abysseye_ ] #rescaria #Aprilia #RS660 #isleofmantt
