Speed B2101 Ty Tessmann Edition

Product Description

A special release of proven World Champion power.

Ty Tessmann tore up the track at the 2014 IFMAR 1/8 Scale Off-Road World Championships running an O.S. Speed Tuned B2101 engine tailored to his winning specs. Now O.S. makes that same setup available to other drivers — in the Ty Tessmann Limited Edition Speed Tuned B2101.

The Limited Edition B2101 features the same tuned pipe, manifold and carb restrictor used by Ty to win the 2014 IFMAR Championships. Its T-2090SC pipe is paired with an M2002SC manifold whose added length increases torque in the low to middle range. The 5.8 mm restrictor — not available on any other O.S. engine — matches what O.S. supplied to Ty for extending run time in competition.

Like the standard B2101, this version has a lowered cylinder head; DLC crankshaft with balanced tungsten weights; and efficient, reliable Type 21J carburetor. The design provides stability, predictable handling, instant response and rapid acceleration.

Only a small number are being produced, making this engine both competitive and collectible. The Ty Tessmann Limited Edition Speed Tuned B2101 is easy to distinguish from the standard model. Look for the natural-color cylinder head and Ty's name laser-etched onto the crankcase, crankshaft and tuned pipe.

"I compete in major races all over the world, in all kinds of conditions. Many things can go wrong, but I never worry about my O.S. engines. They're powerful, driveable and consistent."
