RB X11 Cross 11 + In-line set pipe 198P/2087P

Released last year, the X10 has already established itself as a benchmark for performance, stability and reliability.
Still coming with a 3 ports sleeve with MES (Multi Exhaust System), its 2011 version, the X11 is even more developed.
It receives a black coated crankcase for a better cooling and a lightweight cooling head lowering significantly the center of gravity.
