2015 Rex Legend nitro off-road engines

Novarossi introduce the new Legend line of Rex nitro engine for off-road buggy and truggy applications. Starting with the .21 buggy engines, the Legend 7 and Legend 4 Off Road engines both offer a long stroke design, new rear ball bearings with less rotational mass, redesigned 3-needle carburettors and updated venturi inserts for optimised performance. Both engines are available with standard steel or ceramic bearings.

Also new are the Legend 28 and Legend 25 nitro truggy engines. They feature composite carburettors, a 7-port design, turbo crankshafts and turbo combustion camber inserts. With the .28 engine being of a short stroke design the smaller .25 is a long stroke engine. Just like the buggy specific engines the truggy power plants are available with standard steel or ceramic ball bearings.
