has been designed and develloped internally and externally by Rody Roem. The
weight has been kept to a minimum and its cooling capacity's to a maximum,
it is more rigid and as you can see on the photo extra cooling has been
applied on the bottom of the crankcase to get better cooling. |

Porting:
Its 7-ports system will give you good
torque at low rpm and usable power with good fuel-consumption. The moulding
of the crankcase is realized with a vacuum system to avoid air cavity's
during the moulding process.

The piston/Liner is of the type ABC
chromed and rectified, the piston fits with precision in the sleeve to get

generations of high competition racing RB Concept engines, the crankshaft of
the RB Concept WS7 has received our RB Concept Coating which increases the

steel insert which goes through till the top of the housing, so strength and
stability is assured.

are delivered with the carburetor.
