BIG DEPS 4 cylinder for Piaggio mopeds 75cc tuning cylinder Malossi MHR BIG DEPS 4 for Piaggio Ciao / Piaggio Si. The BIG DEPS 4 is the most powerful cylinder from Malossi for Piaggio mopeds. It can only be used in combination with the Malossi MP-One crankcase, with 4 studs (as opposed to 3 on the original crankcase). This Malossi innovation allows optimization of the transfer ports and a bridged exhaust design. Malossi is the only manufacturer to offer this type of exhaust for Piaggio Ciao, Si ..etc. in 2022. The 4-bolt flange is designed to be fitted with the Malossi Too Bad exhaust, which in turn is perfectly tailored to the Big D.E.P.S. cylinder. To exploit the full potential of this cylinder kit, you will need a Malossi MP-One crankcase, a Malossi Power ignition, an Overrange CVT kit, a PHBG 21mm carburetor, a Malossi Too Bad exhaust and, of course, a few hours to set up your new racing moped.
