OS has always listened to the top drivers who run their engines. By doing so, they can respond to the changing needs of racing and keep their designs at the very cutting edge of technology. The B2101 is very much an engine driven by driver feedback and technical advances alike.
Just about every component has been re-designed from the Speed 21XZ-B Spec II predecessor in order to give you the very best engine on the market. Whether it’s the DLC coated, gas flowed crankshaft with Tungsten balance weight or the specially coated brass liner with high silicon piston, or even the aerodynamic high-strength connecting rod, to OS, every detail matters in the pursuit of excellence.
The B2101 has a revised ‘square’ bore/stroke ratio to change the torque into a more useable area for off-road use, yet still give the top end power you would expect.
