New CXR SLS9 “IELASI TUNED” by RB

World Champion brand RB Products decided to keep the similar on-road engine philosophy to ensure the best performances and especially the great reliability of the 2014 engines. In fact all drivers and customers provided us very positive feedback ! The new CXR SLS9 receives a new cooling head with 10° thins to improve the cooling.

The new CXR is a Super Long Stroke engine with higher technology to be the most efficient (torque and end power) .21 on-road engine !

The carburetor has got a double adjustment with the extra spraybar made in brass to be very accurate with the opposite needle.

The body of the carburetor receives thins to have a better cooling. Delivered with 8.5 and 9.0mm aluminum orange anodized restrictors.

Made in a very hard special aluminum (longer life), the piston is machined with a special rounded & curved top shape. The bottom slim shape of the piston make it very lightweight for maximum possible performance.

The sleeve is made from hard chromed brass and features 9 transfer ports and a Multi Exhaust System (MES). There are two extra holes for a better lubrification. The special shape and positioning of the ports improve the internal fluid-dynamics to obtain the maximum possible performance. The conrod is made from ultralight but strong aluminum which has been twice checked ultrasonic. The form is optimized to maximum reduce the turbulence inside the engine while running.
Last, each piston is coupled with the sleeve to get the best compression and longevity. This operation is made by hand, one by one and checked by a specific precise measurement tool.

The new cooling head is a light and 50mm diameter with a low gravity center. It is drilled and milled out to reduce head's weight. The 10° angle thins also improve the overal cooling.

The 14.5mm turbo crankshaft is lightened and fill-in with silicon paste to reduce rotation weight. The internal channel is grinded to improve the fluid-dynamics and the special shape of the flange reduces the internal turbulences inside the crankcase. The balancing is done by three inserts made of tungsten alloy.

The turbo combustion chamber has a special shape to increase the performance during combustion. The high temperature o-ring avoid vibrations and also protect the assembled sleeve/crankase from external dust.

The front bearing has a double rubber shield protection against dust. The main bearing is calibrated and selected with 9 ceramic balls, it is assembled by hand and its tolerance is twice checked by a specific measurement machine.
