RB introduce their new line of BXR .21 long-stroke off-road engines. All of them feature a CNC-machined piston, lightened 14.5mm turbo crankshaft, turbo combustion camber insert with O-ring, dust-protected front bearings, a lightweight low CG cooling head and a 9mm composite carburettor with 6mm, 7mm and 8mm venturi inserts. First up is the BXR SLSDI5 super long stroke engine. Featuring a 5+2 port MES technology liner and RB’s direct intake system the engine offers increased throttle response and top speed making it ideal for tight high-grip tracks that also have long straights. The engine is made for the use in buggies and truggies.
The second new engine is the BRX SLS5 with 5+2 port MES liner. Just like the SLS5ID the 5-port engine features a ceramic 14.5mm main bearing, competition conrod and 14.5mm turbo crankshaft. The special characteristic of the engine gives a high low-end torque for tight and twisty tracks. Next up and the last in the line of the super long stroke engines is the SLS3. Coming with a 3-port MES liner, standard main bearing and lightened 14.5mm crankshaft the SLS3 offers good low-end torque for short tracks where acceleration is critical. Last but not least comes the BXR LS5 long stoke 5-port MES technology engine. Designed for being a good all-round offering the engine should feel at home on a variety of tracks.
