The bike in brief

The AF1 Sintesi was called , not without reason , the replica of the beautiful small and exclusive Honda RC30 born for endurance races , and in fact the resemblance is so great : analogeno twin headlights , single-sided swingarm with offset wheel , the generous braking system, the fairing polymer perfected in the wind tunnel and the rear seat to match the codon seems that car, are all decidedly corsaioli and that reflect what already vistio on the RC30 . The quality of the plastics and the level of finishing is generally excellent and many valid components present on the previous AF1 were maintained ; the beautiful and complete instrumentation produced in Japan and the electrical controls CEV then remain the same mounted on the Project 108 .

To facilitate maintenance , the tank is now tipper ( after unscrewing a special Allen ) and can be maintained in a high position , thanks to a rod , and thus gaining access to the battery ( now placed in position behind the steering head between the beams of the frame ) , the expansion tank of the cooling system and of course the candle.
