RR complete Engine (water cooled)

The RR 150cc engine is reed valve aspirated (big reeds) and built with Quattrini's RR crankcase (external threaded rods). It's perfect extreme acceleration races where its performances are the best. The thermal unit is composed by an aluminium cylinder (reed valve asppirated, nikasil covered, 60mm bore, 51mm stroke, 150cc, booster exhaust, 5 schnuerle portings), aluminuim interlocking head, printed and lightweighted piston (1 piston ring). The exhaus pipe is handmade and straight mounted. Polish intake manifold and 39mm diameter carburetor already set up for the engine. The full circle Quattrini's crankshaft is made of strengthened material. The ignition is a 20mm cone Vespatronic, 1kg flywheel with variable timing advance. The M2 clutch is modified with 4 covered aluminuim disks and double spring. The clutch cover has a long lever. The Faio's race shif cross is made of special quenched material and installed on the gauged and smoothed gearbox. About the primari ratio, we propose various set up based on the customer preferences. The water cooling system includes a built-in pump on the crankcase that take mechanical movement from the 3th gear. Tubes and radiator are not included. In the straight version the engine has 45hp at 12.000 rpm. All engines are shipped aready built, they are just to plug and play on the vespa body. We guarantee the availability of Angelo Zirri for any question or technical support for the use and installation of the engine and every spare parts needed.
