Not sure if you have found one. Your bike would be one of the Morini motor ones (air cooled), sadly you will be struggling to find a clutch. 1999 KTM 50 SXR Adventure Engine S5-E | KTM World KTM has stopped supplying them. Moto Morini seems to be back operating but, as far as I can see, does not have a 50cc motor/bike in the range.Hi new this group.. Was wanted some help in sourcing a stock clutch hub(basket) for my sons 1998/1999 model ktm50.. Any help appreciated cheers
