To celebrate Ty Tessmann’s ROAR Fuel Off-Road National Championship in the 1/8-Scale Truck class, O.S. Engines released a new limited edition version of the Speed 21XZ-B Spec II called the Ty 110%. Based on the original XZ-B Spec II, the engine includes a 7mm carburetor venturi as well as a new 90mm header - the longest O.S. has ever made, which was a special request by Tessmann himself for more consistent idling and lower fuel consumption. Additionally, the engine is fitted with a new cooling head that sits 4mm lower for greater stability. The engine will be available by itself, or with the 90mm header and T-2090SC pipe.

O.S. Speed 21XZ-B Ty 110% engine - #1217D, 42800 JPY ($382 USD)
O.S. Speed 21XZ-B Ty 110% combo set - #1217E, 51500 JPY ($460 USD)
