OS SPEED B2105 ONGARO EDITION W.C. V3 Comboset

This is a world championship model commemorating Davide Ongaro’s 1/8 off-road buggy world championship victory.

This is his second consecutive victory with O.S. Speed but his third consecutive victory.
The outer head is based on B2105 with black and gold double anodized specification requested by Ongaro. The laser design with “V3” logo has been added to the laser engraving.
Crankcase with special laser engraving and with shiny “O.S. SPEED” and “B21” logos on both sides.
Carburetor reducer is the same φ6.5II that was used by Ongaro during World championship. It is 24k gold plated as World championship model. TB02 tuned silencer comes with Ongaro’s signature and “WORLD CHAMPION” logo.

• The newly designed cylinder and liner applies 3 ports. The port shape has been changed and the air-fuel mixture flow has been reviewed to achieve more torque from mid to high end.
• The modified crankshaft has undergone O.S.SPEED's traditional DLC coating and the internal shape has been revised to improve not only power characteristics but also easier to use than B2104.
• Drivability is improved by reducing the weight of the outer head.
• Inherited from the well-established B2104 crankcase. The bearing inside the case also uses a proven ceramic bearing.
• By adopting a specially treated thrust plate for the cover plate adopted from B2104, wear caused by friction between the rotating connecting rod and the cover plate is reduced and engine life is impiroved.
