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 . Improved, however, mirrors that are now the most pleasant and the most modern design and the double front headlight that is larger in diameter than the unit mounted on the AF1 Replica . 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. Raising the passenger seat , protected by a lock , you enter the tool box and tank for mixing oil , now situated to the rear . The air box is always located on the right side as on the Project 108 and is easily accessible.


The chassis is an evolution very advanced compared to the AF1 Project 108: the beautiful twin spar frame diagonal extruded aluminum is much stiffer and lighter than the old frame of 108 AF1 Project . The front fork upside-down from well- 38mm is entirely new and is not adjustable : its presence led to the change of the plates, always with elegant design and come with a bump to the ignition switch. The single-sided swingarm in boxed sheet steel and a valid progressive rear suspension (again SEBAC not adjustable) APS , remain the same seen on Project 108 .

The braking system now adopts a new and splendid front floating disc 320mm ( the first case between 125cc) and equipped with a caliper ( Brembo ) has four pistons with differentiated diameter ; remains valid at the rear 240mm disc served as dual-piston caliper of the previous AF1 . The beautiful new 17 "wheels , home to the new Pirelli MT 79 respectively valid shell in sizes 100/80-17 front and 130/70-17 rear .

The dry weight down to 131kg , compared to 134kg recognized on the AF1 Replica .


The engine is the new Rotax 123 , which is an engine designed from scratch than its predecessor Rotax 127. Here are the key innovation with respect to the engine mounted on the AF1 Reply :

· New aluminum cylinder with reed treated to Gilnisil ( cast iron barrel on AF1 )
· New two-piece cylinder head for improved cooling
· Stroke increased by 0.5 mm (size 54x54 , 5 54x54 instead of the Reply )
· Compression ratio fell to 15:1 ( 15,5:1 on Replication)
· Balancing countershaft (absent on the Rotax 127)
· Valve RAVE 2 , always with pneumatic control
· Carburetor Dell'Orto PHBH 28 RD oval section
· Air Box with dynamic air intake mounted on the right side of the motorcycle.
· Primary drive slightly longer , the last two gears and final report shorter extension to make better use of skills

In view of the changes , the engine detects a summary of the maximum power to the wheel of 28.66cv to 10500 rpm , a slight worsening in terms of absolute power than the Rotax 127 mounted on AF1 Replica ( 29.24 hp at 10250giri ), but all advantage dispensing much more substantial at low and medium revs and therefore more space, also because of the reports reviewed. Synthesis fact check qualities of exceptional recovery : evidence of recovery in the 400 meters to 50km / h , time is of 19.352 seconds and a speed of 96.26 km out of well / h instead of 21.115 seconds and 82.80 km / h measured on AF1 Replica . Although the maximum speed improves : 163.9 km / h instead of 160.5 km / h measured on AF1 Replica .
