The torque limiter and secondary gear (the one behind) is special parts for Highland. I dont know where to get those nowadays. The torque limiter is the one part that makes the Highland a bit unreliable.... and the reason i sold it :-( The sprag clutch is KTM part no. 58440026000. I have used that part and it fits perfect. The start motor should be the same as BMW F650/F800 1993-2008 models. Denso part number 228000-6900.
