    WTB - Akront TR style WM4 / 2.50x18 36 hole rim (or similar)

    Like the title says,
    I'm searching for an Akront TR style WM4 / 2.50x18 36 hole rim (or similar cosmetic match in Borrani/Akront/Morad or knock-off).
    I have a 4.25x18 wm9 40 hole for the rear to lace to my Rickman hub so that I can run a 150/70-18 on this 125hp beast of a GS1000-1105cc engine, but all I can find up front is a 2.15x18 or else a silver anodised DID rim of similar profile that would need stripped of the anodizing (p.i.t.a.)

    Yes, Rickman hubs are 40 hole, but I was unable to find a Rickman front dual disc hub. I thought I found one, but it turned out to be nearly identical in appearance but actually is Italian Scarab-Mozzi 70's Superbike hub that looks 95% like a Rickman. Close enough for this given how hard they are to come by. The front hub that is a cosmetic match to the Rickman is a 36 hole

    I was originally searching for a Borrani shouldered flanged rim like the original Rickmans, but they only go up to 3.00x18 wm5, & I am putting out A LOT of horsepower and needed something more substantial in terms of rear rubber.

    Thanks for your help

    This style rim profile, but in a 2.50x18 36 hole



    To match this:

    I think you forgot to mention if you are wanting to run a tube or tubeless tire.

    Did you check over at MikesXS ? Their rims are not Italian but the same style. I just checked and have one in the shop that is still in its box.

    The rims at MikesXS are all either straight sides or deep H-profile with the noticeably taller sidewalls.
    All the tires I run go tubeless or tube, but I generally always run a tube. I would like to entertain the idea of tubeless at some point though, but mostly for my touring bike (gs750) for ease of roadside flat tire plugging. Lighter weight is a big bonus to tubeless. Free hp and better suspension action.

    Teazer, what type of rim is this that you have in the box at the shop? 2.50x18 36 spoke?

    The lip on the outside nearest the tire bead seat, is that what is referred to as the flanged part, or is that the shouldered part, or do both these words describe the same thing? I thought one may denote the BorranI "H" profile and the other denoting the lip at the outside of the sidewall.

    Thanks

    2 front Scarab-Mozzi-Motor Italian dual disc 70's hubs (36h) next to a Rickman CR rear hub... all 3 & the undrilled 11" Rickman rotor are NOS never used!!! The drilled 10" Rickman rotor has seen some serious use and will see more in the future on my build!

    MikesXS is a sweet source for rims, but they cannot provide a matched set of 2.15 front and 2.50 rear, which is what I keep hoping they'll have. One would be straight flat sidewall, the other a flanged shouldered H profile...

    Here maybe this will help:
    TR type = "The 'Turismo Reforzardo' is a reinforced rim although not quite as strong as the TC. Being also lighter, it is used in supermoto and trials racing to reduce the weight of the wheel and is popular on custom motorcycles thanks to the huge range of widths available."

    It came from MikeXS and is 2.50 x 18 36 hole and is polished but is NOT the flanged/valanced type we are used to seeing on skinny vintage Italian rims. It's closer to the TC shape than TR and the shape is clearly designed for a tubed tire as it does not have the bead seating shape required to retain a tubeless tire. I'd be surprised if Mike's don't still list it.

    Opinions, please...???

    What do you guys think of this rim I found NOS in Italy for a bargain price? The photos aren't the best, with tricky lighting and angles. I can't tell if it's the H-profile valanced rim that is common of Borrani or not.
    It's listed as a Borrani Record, and in the size I am needing.



    Would that be a decent enough match to substitute for an Akront TR wm4 like this? These two pics are Akront TR's to match the rear, but this one is $$$ NOS & 1 size smaller than I was looking to run on this monster engine's Rickman CR



    I was trying to steer away from the tall sidewall typical H-profile valanced Borrani look slightly when using the Akront TR rear rim, despite the H-profile Borrani's being what was originally on Rickman's (can't get a rear in anything wider than 3.00x18 which is standard Rickman setup, I need a 150 rear tire, not a 120/130... way over 100hp @ 1105cc's.

    Does that Borrani Record rim in the 1St w photos of this post look like this (below) in real life, are the pics deceiving? Or is that a slightly shorter sidewall and rounded top edges on it, as to match a little better with the 4.25X18 Akront TR rear? Typical Borrani H-profile valanced rim below, straight on side view:

    Well I found that ebay sellers website, & that borrani record rim IS the H-profile. The good thing is that their rims are cheap as heck! I could get new a new Borrani set front 2.50x18 AND rear 3.00x18 for $271 shipped!!! That's about the cost of just the rear 4.25x18 Akront TR...

    I really felt as if I needed AT LEAST a 3.50x18, & although a 140/70-18 & 140/80-18 are aa good fit on a 3.00 & a 150/70-18 is an acceptable recommended fit on a 3.50, I felt the best route us to go with the size rim a 150/70-18 is listed as the best possible fit, a 4.25x18
