OS Engines Speed B2104 .21 Nitro Buggy Engine - OSM1DA00

OS SPEED's off-road racing engine has evolved even further! The 4th generation of the B21 series, the "B2104" is a long-stroke engine that has improved response in the low range, more torque in the middle range as well as consistent idling.

Features

New piston/liner is a conventional 3-port type enabling more torque over the power range
The new crankshaft has DLC coating as we always do for OS SPEED engines. The two tungsten counterweights are embedded in the crankshaft contributing consistent idling and quick rpm down according to throttle move
The thrust plate with surface treatment embedded in the cover plate reduces friction against a connecting rod to extend its life
The boost port and the exhaust port of the crankcase are redesigned for optimum air flow
The carburettor is trustable 22E type, which is featured in the OS Engines B2103 Type R
The cooling head is conventional round-shape type with standard height
