It would depend on the particular motorcycle's completion date.
It would appear that the first half of 1960 model year production did not get the 60R parts while the second half did.
Copies of the blue prints with introduction dates or the bill of materials for the 1960 bikes would be the only way to say for sure.
No Date Race Department Notice to Dealers lists -59R parts cylinders, heads, valves and -58R exhaust "A" cams that were not available until after Jan 1, 1959 so last half of the 59 production. No mention of alloy fender or supports. Also lists numerous 58R and 59R aluminum parts, rear motor mount, front motor plates, front motor plate spacer, KR cylinder brace spacer, KR upper valve collar spacer, KR valve collar, KR valve spring upper collar, KR key for valve collar, that are not part of the bike as delivered and only available as a part order.
July 59 1952-59 Spare Parts for Competition Models, 99451-59R, no mention of the alloy fender or supports
November 9 1960 Race Department Supplement to the Parts Catalog, lists the aluminum fender -60R and fender supports -60R.
