Davide Ongaro, the winner of the IFMAR 1/8 Engine Off-Road World Championship, has signed with O.S. SPEED since 2021. This engine, the "O.S. Speed B21 Ongaro Edition", has been created to match his requirements!
Based on the latest off-road engine (O.S. SPEED B2104), the crankshaft has been changed to a counter web shape and uses a single tungsten weight that has been specially made for this engine to suit his driving style. The inner head also has a specially designed combustion chamber, and the effects of these changes give a smooth driving feel and a more powerful top end. In addition, the outer head adopts a standard round type, and the laser marking of Ongaro's original logo mark.
A new size ø5.8mm / ø6.3mm black anodised restrictor is also used for the carburettor to create an "Engine that can win big races" that matches his requirements.
