O.S. Engines B2102 Engine With Low Profile Head [VIDEO]

From O.S. Engine:

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 go low, while the others go home.
