O.S. Speed B21 Ongaro Edition

Davide Ongaro has his first Ongaro Edition O.S. Speed B21, having joined the Japanese brand at the start of 2021. Modified according to his own feelings, it is based on the latest O.S. Speed B2104 off-road engine. The crankshaft has been changed to a counter web shape and uses of single tungsten weight specially made for this engine to suit his driving style. The inner head also has a specially designed combustion chamber, and the synergistic effect of these gives a smooth feeling and more powerful top end. In addition, the outer head adopts a standard round type, and sports Ongaro’s original logo mark. A new size φ5.8mm / φ6.3mm black anodised restrictor is also used for the carburettor to create an “Engine that can win big races” that matches his requirements. They will also have a combo set that includes the TB02 (also known as T-2090) EFRA 2089 tuned silencer with MB01-75 (75mm) manifold.
