http://www.apriliagenuineparts.co.uk/component-sr-125-150-1999-2001-crank-case-4282.php Most likely to be number 14 on that diagram , have replaced several and it can be a pain in the ass, if your methodical enough about it everything will fall into place . engine has to be removed for the bearings to be fitted . Also check the poly bushes (number 6 on the link you posted) these often wear out and are a piece of cake to replace .
