ULTIMATE RACING NEWS! Ultimate Racing is super excited to launch the new MXR Ceramic 3 Transfer .21 Off-Road Competition Engine. Like its predecessor the MXS, this engine is manufactured by the prestigious Japanese brand O.S. Engines, in this case based on their square stroke Speed B21 engine. Apart from the modifications that the MXS already had, such as the crankshaft and back plate, the sleeve of the MXR has been modified, modifying the ports to be able to vary the inlet and exhaust timing. The inner head has also been modified and includes the innovative FlowMax venturi to improve performance, more specifically, to achieve greater power without compromising fuel consumption.

This engine provides a really good power band with a ton of usable power. It has a smooth bottom end which worked well on the bumpy track and then has a lot of mid-range pop and feel to it. It is one of the best idling engines you can find on the market.

This engine is also available as Team Edition (broken in) and Combo with both, the 2141 and the 2142 pipes.
