Please can anyone confirm as the headlamp bucket/shell was supplied by a honda specialist as a replacement for the original.

Thanks greg

I believe the lamp is 5 and 3/4 inches. The bucket is 7"
'Then' and 'than' are completely different words and have completely different meanings. Same with 'of' and 'have'. Set and sit. There, their and they're. Draw and drawer. Could care less/couldn't care less. Bought/brought FFS.

My headlight is 6.5 inches. A US-style sealed beam of the same size also came with my box of bits.

ID of the rim is 7".

I have a extra 77 trim ring, give me 10 to measure it and I'll post back.

Thanks everyone - looks like the bucket/shell is correct so now have to find rim/trim and light.
