the R mid belt is 384mm with 19T pulley in the rear and 27T in the front.
the factory provides you with a front 25T pulley in case you need OD. I have not use a 18T in the rear but only use a 25T in the front and i need to use a 375mm sp belt.
k factory has two low friction belt. one is for 27T standard pulley and the other one is for 25T OD pulley
