OS Speed ​​Engine B21 "Ongaro Edition" SET - 1DL01

Davide Ongaro, who won the IFMAR 1/8 Motor Off-Road World Championship, has been contracted to OS SPEED since 2021. This time the "OS SPEED B21 ONGARO EDITION" was born, modified according to his ideas!

This is a combo set:

  • Engine B21 Ongaro Edition
  • TB02 (Also known as T-2090) EFRA 2089 tuned silencer
  • the exhaust system of the / MB01-75 (75mm) manifold.


Based on the latest OS SPEED B2104 off-road engine, the crankshaft was changed to a counter-cheek shape and used a tungsten weight crankshaft made specifically for this engine to suit its driving style. The inner head is also specially designed combustion chamber, and the synergy effect of these realizes a smooth feel and more powerful top end. The outer head is round as standard, and the laser marking with the original ONGARO logo creates a racing atmosphere. A new size φ5.8mm/φ6.3mm black anodized throttle body is also used for the carburettor to create an "engine that can win big races" that meets its requirements. We also have a combo set that includes the TB02(As known as T-2090) EFRA 2089 tuned mufflers and the exhaust system of the / MB01-75 (75mm) manifold.
