Quick Links
Manuals & SupportTuned to take the track!
OS makes every competition hotter! The B2102 Competition Engine is, as its name suggests, a born competitor. It's designed with a low cylinder head for reduced center of gravity for superior stability when you blast around corners and slam down the throttle on the straights. Plus, it's equipped with a 22C slide valve carburetor for better fuel economy and a silicon potted, tungsten-weighted crankshaft with a hard, diamond-like coating. From the P3 Turbo Glow plug to the polished tuned pipe, this engine is every inch the competitor you need to take the track.
