21ONG OSSPEED B21 Edition 2022 Davide Ongaro World Champion

Davide Ongaro, who won the IFMAR 1/8 Engine Off-Road World Championship, has signed with O.S. SPEED since 2021.

Now the “O.S. SPEED B21 ONGARO EDITION”, which has been modified to his liking, is born! Based on the latest O.S. SPEED B2104 off-road engine, the crankshaft has been modified with a specific shape and the use of a tungsten weight, specially designed for this engine according to its riding style. The combustion chamber is also modified and the synergistic effect of these provides a smoother feel and more power at higher revs. In addition, the cylinder head has the original ONGARO logo laser-marked on it to create a racing atmosphere.

A new 5.8mm/6.3mm black anodised venturi is also used for the carburettor to create a ‘big race capable engine’ that matches its requirements.

We also have a combo kit that includes the TB02(known as the T-2090) EFRA2089 resonator with its MB01-75(75mm) elbow.

DLC coated ONG crankshaft with tungsten counterweight for smooth rotation and better balance.
