output shaft bearing

[no class]

can someone confirm if the 91-92 gsxr 1100 output (drive) shaft has a double row bearing ?   I need to swap out the shaft and bearing on my gen 1 bandit 12 motor.....part numbers are the same for the shafts and bearings....the spacers are different ....19mm gsf....18.1 gsxr.....I seem to recal reading about the gsxr bearing being a stronger upgrade for the bandit one.....but then again I may have been on the juice that night .

The 1100 M/N and B12 have the wider bearing and longer output shaft, I haven't heard one is stronger than the other though ? didn't know the spacers were different..

 I have been reading some crap posted on the net about the b12 output shaft bearing failures....on lowish km motors..... now..... my gsxr's from days gone by (L , M , N ) all had above 35-45 k on the exception of the L model ..... never had or heard of a bearing failure..... second gear yes...... bearing no . I just can't remember if the 91-92 bearing had double row bb's.   The bandits have 1

From what I have read the b12 & gsxr 11 m/n have the same gear boxes. But yes the spacer to the sproket can be different on all modell. The b12 is left over bits that Mr suzuki used last (that's how I think of it).

If the part numbers are the same....... the bearings are.
