2 stroke ktm big end bearing pronblems

has any one had any big end bearing problems with a 2012-13 ktm 125 sx

choosing between ktm or Yamaha 125

I'd focus more on the difference in power and chassis handling to fit your track , body size and style. 125's are gonna need cranks, hopefully as part of maintenance not later.   DirtRider has 125 test you might read.  ktm, yz, husky, TM

Put cranks in both of them. The YZ with 144 kit seems to use them up quicker
