1A300 O.S.SPEED B2102

The O.SLow profile = high performance

One look at the Speed B2102 engine and you'll notice: the cylinder head is significantly shorter than those found on similar power plants. It definitely looks cool, but looks are just a small part of it. The Speed B2102's lower profile drops the center of gravity by an impressive 17 millimeters. That boosts your buggy's handling big-time, which can be a real difference-maker on race day. Mount the Speed B2102 in your ride and you'll go low, while the others go home.
Unveiled at the 2016 IFMAR 1/8 Off-Road World Championships
Hug the track and conquer the corners like never before, and without sacrificing cooling performance
Ceramic bearings let you run cooler with no special handling or cleaning — they're also lighter, create less friction and last longer than steel bearings
Enjoy up to ten minutes of run time per tank with the Speed B2102's more fuel-efficient 22C carburetor
O.S. Speed innovations include a tungsten weighted crank shaft with diamond-like coating and silicon potting

Also available with a T2090SC muffler SPEED 21XZ-B Spec III is the evolution of the Spec II, which has enjoyed much success at races all over the world. Low- to middle-range torque has been enhanced even more, providing a great advantage on tracks that require lots of power. You’ll easily hear the difference in the engine’s roar when warming it up on a starter box, and once you’ve raced with the Spec III you’ll want to stay with it.

The newly developed cylinder liner features 3 scavenger ports and 3 exhaust ports, and works with the newly designed crankcase to deliver more torque with less fuel consumption. To improve drivability, the drop-in type outer head is lighter, with a lower CG than the Spec II. Some components could not be improved upon, such as the silicon-potted, DLC coated crankshaft with pressed-in tungsten weights. The carburetor is also the same easy-to-tune 21J with 6.5mm restrictor. When you add the Spec III upgrades to the legendary O.S. SPEED 21XZ-B engine, you have a dependable, high-performance powerhouse.
