O.S. Speed 21XZ-B Engine (L-OS12186) Developing on the 1/8th Off Road World championship winning engine of 2008, OS has now devoped the latest generation engine called the Speed 21XZ-B. Racing engines are a constant refinement of design & technology rather than a huge leap. The Speed 21XZ-B is case in point. No one area has been dramatically changed but nearly every area has been subtly enhanced. Whether that is the DLC coated, tungsten weighted & silicon filled crankshaft, the Ceramic rear bearing or the shape of the cylineder ports, everything has been developed to make the Speed 21XZ-B a step forward in performance. OS racing engines have always been some of the easiest to set up & use & this is no accident. Years of racing experience with top drivers such as Mark Pavidis & Atsushi Hara has established how an engine should respond at the highest levels & remain consistent. There are small detail changes such as the lower, lighter heatsink head for a lower centre of gravity & an enhanced 21J2 (B) carburettor for better response & setting. The Speed 21XZ-B has an overall fuel consumption that is 8% better (OS pipe) than its predecessor. That could make the difference when making a decision about the best time to pit! Why not follow the champoins choice & drive the very latest Speed 21XZ-B yourself! Optional items: Super Air Cleaner 203T-2060SC WN Tuned Pipe system (EFRA 2042 homologated)P4 & P5 Turbo plugs (Cooler) Crankshaft locking tool Heavier Flywheels for Mugen & Kyosho Flywheel Puller Flywheel Key Long Plug Wrench Specification: Weight: 355g (12.52oz) Displacement: 3.49cc (0.213cu.in) Bore: 16.27mm (0.64in) Stroke: 16.8mm (0.66in) Power Output: 2.6PS @ 34000rpm Practical RPM: 4, 000
