O.S. Speed 21XZ-B Spec. II Ty 110% limited edition engine

O.S. Engines have introduced the Speed 21XZ-B Spec. II Ty 110% limited edition nitro off-road engine. The power plant was used to win the Nitro Truggy title during this year’s ROAR Fuel Off-road National Championship in the hands of Xray’s Ty Tessmann who also gave the name to the new engine. Features include a 7.0mm venturi insert as well as a 90mm manifold for consistent idling and lower fuel consumption. The package is rounded out by a 4mm lower cooling head for an overall lower centre of gravity and also included in the combo package is a T-2090SC exhaust pipe. Beside the combo pack the engine is also available separately.
