I am probably wrong on this, but thought I would add it just in case, but years ago I had an EFE and used (I think?) a Gpz750 front sprocket, which was offset from the factory. But a hefty 630 fitting. I am sure that I heard/read somewhere that some Kwaks have offset front sprockets? ZZR1100?? I don't know enough about the pitch sizes but could an offset (Gpz750) sprocket be machined down to a more user friendly 530? I admit that I am stupid in not knowing the sizes of the chain pitch. If my 5 year old grandson was here he would no doubt be able to tell me.
