Description
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 anodized restrictor is also used for the carburettor to create an “Engine that can win big races” that matches his requirements.
This combo set includes the TB02 (also known as T-2090) EFRA 2089 tuned silencer and exhaust system using the MB01-75 (75mm) manifold.
