For those still running the BX and BXR the previous generation RB we have got a better result from changing the to a medium header instead of the long one supplied in the combo kit .It basically adds power everwhere ,perhaps if you battling for traction and then the longer could be easier to ride though.

We should be goiing over to the new SLSDI5 and SLS5 this weekend and will test the make the same swop to see if the result is similar .
