O.S Speed have released the next incarnation of their World Championship winning buggy engine with the release of the 21XZ-B. This 3-port engine features smoother power delivery and an 8% improvement in fuel efficiency. The motor sports a new hardened and lightened crankshaft that uses tungsten weights for balancing, and this is mounted inside ceramic bearings for reduced rolling resistance. The cooling head has also received some attention, being lowered by 9mm and lightened through the use of holes to help lower its centre of gravity.

Seen during our coverage of the World Championships in Houston, O.S. Speed have released further details on their new line of on road exhaust systems. These new exhausts are fixed to the manifold with a pair of aluminium clamps which prevent the silencer from disconnecting during races. Unlike conventional spring connection, the semicircular clamps enable the adjustment of the pipe to any direction. The pipe itself makes the low to middle range response of the engine more snappy while maintaining top speed power. Available for the .21 (FEMCA & IFMAR legal) and .12 (EFRA & IFMAR legal) engines.
We wrote about these tools back in January when they were first announced but there have been some additions to the range since then, mostly for gas racers. Made from the highest quality materials to the strictest tolerances for superior performance, comfort and reliability, the diamond pattern grips make the driver handles easy to hold, while three flat sides keep tools from rolling off the pit table. Indicating grooves let you identify tip sizes at a glance and each handle has end caps with a rubber O-ring that allows it to rotate in the palm. The tips are made of CNC machined spring steel and can be retracted into the handles for storage, or to adjust for the desired length. The new additions include a clutch nut wrench, a flywheel holder & clutch gap tool and finally a flywheel puller. Available in US in mid-June.
New from O.S. Engines is the Max-25XZ Truggy Engine, that utilizes the best balance of power, fuel mileage, size and weight within ROAR regulations to give racers optimum performance at 1/8 truggy and stadium track events. This motor is designed to have more power than .21 class engines, yet less than the .28 class, for better fuel mileage, lighter weight and lower centre of gravity. The supplied double adjustable type carb gives smooth acceleration from low, mid and high speeds.
