The arms race continues! After spawning outstanding cylinders such as the M1 and the Parmakits, the Italian sprint racing scene has now bred a new brute weapon –curtain up for the FALC. These cylinder kits are handmade by the little tuning company Falc Racing and every cylinder receives a final individual rework by hand. Lauro Cafforio has cylinder kits with a displacement of 130cc, 144cc and 152cc on offer. Enough options for those who are looking for more displacement and torque!
The 57x51 is the ideal choice for POLINI/MALOSSI converts. In order to get more than 20 PS out of these old names in the business you have to invest a considerable amount of money and know how. The FALC offers you a performances of up to 24hp with a disc valve manifold and without having to rework the engine casing. Thus, the QUATTRINI M1 has found his match.
Conclusion: next to the M1, this is the ultimate choice in racing cylinders for Smallframe riders who are willing to look beyond the performances offered by POLINI/MALOSSI.
Aluminium / 57 bore / 51mm stroke / 7 transfer ports / 130cc / disc vavle
Aluminium cylinder with coated race, two large divided side transfer ports, 97mm con rod, cylinder head with optimised air flow and standard spark plug position, coated high performance piston with one piston ring, standard stud distance. The periphery of the motor should be matched to the increased performance.
SIP-TIP: Race/Flowed crankshaft with 20/20 or 24/25mm cone, VSP, PM, FRANZ or FALC racing exhaust, 34 carburettor are mandatory. Electronic ignition such as VESPATRONIC recommended. If combined with an HP4 flywheel or PARMAKIT ignition, you have to remove one cooling fin from the cylinder.
Jochen Undesser a.k.a. Undi has done an interview with the grandmaster, 02/2009:
"The new Mono (57x51)looks quite promising and is a true plug&play item, direct competitor of the M1 (the cooling port of the cylinder has to be removed). According to Lauro, 24PS is possible if everything is nicely adapted with a rotary slider. Still 20 hp well to handle possible with his new disc valve crankshaft with 51mm stroke, manifold for a 38!!!!! carburettor and a nice exhaust with standard engine periphery set-up. Of course I had to give his ride a try as he is so proud of it. A smooth ride considering the 38 carb on a disc valve"
