ATTENTION! For the uninitiated this is generally considered the correct left hand R.H.P. main bearing for late Triumph T140 Bonneville TR7 Tiger twins with C2 clearance! For the record, while C2 is actually a tighter than standard (or CN) bearing and can sometimes lead to engine failure if used in an incorrect application. It was used in late T140/TR7 models where there were case and crank variables. CN means clearance normal. Always check the clearance specs for your make and model to prevent damage! Bottom line is that after 40+ years of wear and tear many engines now need different clearance bearings than they originally came with!
