Picco Monza Nine .21 On Road Engine

The Picco Monza “NINE” .21 on-road engine brings a wider power band and refined drivability to serious racers. Featuring a new 9-port cylinder with updated exhaust boost ports, it delivers improved throttle response and top-end pace while easing control in the turns. The result is confident handling and strong speed across a variety of track conditions.

Built for performance and longevity, the Monza Nine combines a hard-chromed liner and CNC-machined piston with a 14mm DLC-coated crankshaft using two counterweights. A die-cast 3-needle aluminium slide carburettor with an 8.5mm venturi provides precise fuel metering, while the die-cast backplate enhances gas flow. A Swiss-made 14mm ceramic main bearing helps minimise friction for smooth, efficient running. Part number PIC9620 ensures you’re getting the latest Picco Monza Nine specification.
