Hand in hand for the titel

O.S.Speed has started a new engine project together with Ty Tessmann to defend his title.
Based on the B2102 (item no. 2818), a motor head with an exclusive design was used which, adapted to its drive, improves cooling.
Furthermore, a 5.8 mm Venturi was installed which improves the fuel consumption in the race noticeably.


The heat sinkis silver anodised, exclusively as Ty Tessmann Edition.
Crankcase and crankshaft are laser-marked with the Ty Tessmann logo.
