paul, because im to stupid to figure out who to get your pics into this reply your going to have to deal with my feeble attempt to describe the parts.
52-e54
used the short offset (or reduced trail or non parallel of you prefer) steel top tree. has 4 mount bosses.

L54-56 & 57-58 sportster uses the long offset version of the 4 boss steel tree.

59-E62 used the 2 boss steel tree.

L62- 72 uses the alum tree with the press in rubbers

73-87 uses the alum with the non press rubbers.
-----------------------------------------------------------------

the 1st alum rear mount used on production bike was for 1961 models.
that mount had a desigm change mid 62

Hi Joe, Hi Paul

After a long search in my back up hard drive...

Here's the KR XLR mid sixties alloy top tree with the old K geometry...

(if someone out there has a clue how to copy and paste an img /img code on a flaming MacBook Pro, it will be most welcome...

Hi folks, A lot of great information, thank you all for helping on this subject. Patrick, unfortunately I couldn`t open your last forward, have no idea why. I noticed that the trees in the H-D archives XLRTT photo have the early 52-53 raked style with tabs and lightweight K or KR frame. So, maybe the archive photo is a 58, or a one off for photo shoot, which wouldn`t help much nailing down the 59 part. The -59 set is not raked. EriK

Ok looks like the photo is a 58 by tank badges... Finally found my KR XR Competition Parts Book. -68 Shows 45738-58RA UPPER BRACKET ASSEMBLY, Aluminum 52-68 KR, KRTT, XLRTT No mention of XLR anywhere so I guess it "is included"? It appears like the alloy one gets the nod. It is great to have you all available to figure these things out. Erik

Eric,

XLR is the engine alone...

XLR-TT is the whole bike (since an XLR as a "full bike", rigid end and no brakes was never listed by the factory).

A few XLR were made by individuals for outlaw races outside the AMA...

That 58 XLR-TT, I posted the date the photo was filed earlier in this topic...

It IS the XLR-TT prototype and as such was probably not sold as is.

A month later, the very same XLR-TT was shot as a XLC and a XLCH with the proper race tank badges, the 59 CH ones...

Excellent. Yes, interestingly the factory reportedly made just one XLR motorcycle but never sold to public or produced them beyond. Went deep into some files... So all other XLRs you see are actually outlaw or XLRTTs misnamed. Just to see what Harley Davidson XLR google search shows there are four or five images of some very nice looking bikes, outlaw XLRs or XLRTTs, all with steel top tree bracket. Probably outlaws. Maybe having the alloy top bracket or not is an indicator of a real XLRTT or a built one. H-D parts books listings changed on later books, with early parts. It says 52-68 KR, KRTT, XLRTT for the alloy one but it wasn't made until 58. In other words it fits or could fit back to 52 KR , etc. Pretty general application. Erik
