Since Rickman-motorcycles.Com in the UK haven't responded to my inquiry about the "Chain Adjusters (complete set)   £38" that they list on their website but have no online shopping cart and only an overseas telephone # for ordering, I may have to cough up $115 for this set of chain adjuster eccentric washers from Speed&Sport who have a lot of Rickman mx parts, says these fit several models and Rickman road bikes.

So this bike had a set of 38mm 16" wheel 86 Ninja forks on it. Not in my top picks, so I ditched the forks but still have the triples in the frame. Based on the 11/16" rear axle & 254mm - 10" even - rear brake rotor, I am assuming the Rickman's were built primarily with standard SAE measurements. That really got me wondering about the steering bearing conversion difficulty.

The set that's in there now is a tapered needle roller bearing setup that is matched up with the Rickman frame and a metric Ninja/GPZ ZX6 triple, & seems to be a perfect fit. Anyone have any advice to add here in this department? I think this will be the last challenging issue to deal with in adapting other parts to this bike or finding placement parts for the existing stuff.

I am getting a set of late model Honda 41mm cartridge forks that work very well with my proposed wheels and brakes, and should be the right height for this frame, and are fully supported by Racetech. hopefully fitting them won't be too terribly difficult with the help of allballs bearing conversions.

From another forum:
Quote from: jalsteve;340040
Make sure he has one on the shelf - He usually doesn't and his delivery time is huge. Also his tanks weigh a ton, definitely not race as the gauge of alloy is way to heavy and quality is patchy.

Hmmmmm....... $835 shipped to USA... They sure are great looking though.  But maybe the fiberglass repro cover onto the original Rickman steel inner tank will suffice. I can't imagine a steel tank plus fiberglass cover weighing much less than a heavy gauge beautiful aluminum tank anyways.

I'll wait to hear back from the tank shop as well. Maybe I can get then to custom make one for me without the half circle indents underneath, if they are better quality that is. Great to deal with so far, the tank shop was.

I would like to get the original hub info and search for one, but I may end up trying to adapt the metric Suzuki hub to the SAE axle that the Rickman swinger requires. No way would I consider boring out the swingarm to even a mere 18mm! And I doubt I'd have much luck sourcing a bearing with a metric o.d. and an 11/16" i.d., and then I'd still have to have all kinds of custom machine work done for the spacers!

I do have some original parts, shoot some photo's for you for a better view on them. Front hub is like the rear with single mounting flange, this front hub looks to be magnesium, they are also made in aloy like the rear hub.  they are also m a.  Forks are 38mm Betor.

This is an extremely cool project. I never realized that they make a longer version of the steel tank/glass cover. I have a setup like this myself with the shorter tank and 2-up seat that I acquired for a CB750 project. I am doing a recreation of the Rickman CR but with my own twist and lots of one-off parts. I have been posting pretty heavily over on the SOHC 4 Honda forum, and will be moving my thread over here soon.

I look forward to more updates!!

Oh wow... I don't suppose that rear wheel is for sale, is it??? If only the front were a dual disc.... beautiful hubs. And rims. I wonder if the bolt pattern for the rear rotor is the same as the one I have here on this rear Morris mag?


I had tried emailing that contact info on the website that you linked, but the address was invalid and the mail bounced. Also at that time just a few days ago, none of the photos worked, they all showed up as a black&white photo of a guy riding a wheelie on a vintage twin, every single pic. I see that is fixed now it seems. Great news!

Sorry, i'm not ready to part with these, took me awhile to find them.
Last rear wheel i have seen for sale was on ebay.com a few months ago: http://www.ebay.com/itm/Genuine-RICKMAN-CR-Road-Race-Rear-Wheel-with-Borrani-alloy-rim-and-brake-rotor-/231656367759

Any photo's from your Morris Mag?  The rickman rear disc is 253mm diameter, 17mm offset, 113mm center hole diameter, 119mm bolt center. ( front disc has larger diameter )

Sorry to hear the website links not working,  i just noticed it's a older site, possibe not updated !

Rear disc on the Morris mag is 113mm center hole diameter, 127mm pcd 6-bolt circle (center to center of opposing bolts), I measured about 254mm diameter which is 10" exactly, and 17mm total offset. I'm never really to certain with these parts if I should be measuring in metric or standard!

this definitely seems to be an exact Rickman rotor, but I think your bolt circle diameter measurement is off, or maybe you are measuring from the edge of the holes inside to inside on the smallest distance, as I do get just a hair over 119mm going that route, & 113mm center with 119mm bolt circle center would give you enough metal to have only 3mm from inside edge to center of bolt hole, so you must have the same pcd

Pardon the neglected condition of this rotor. It would be a very nice piece cleaned up, and I do plan to try and use it, even if I have to use a non-Rickman hub, I will consider machining an adapter to mount it. Pardon my fractured wrist/brace as well - I am using my bad hand to point at the Morris Industries "Circle M" logo at the valve stem.

A very worn out pointy toothed aluminum 37t sprocket on the other side, with the bolt-on drive side sprocket carrier/bearing retainer welded to the hub! Sheesh. several signs here that the bike was definitely raced, safety wired bolt heads and all, steep gearing for top end, typical headstock fillet-brazed/bronze-weld joint cracks repaired on frame and additional gusseting added, etc.

I will be very very happy to put this thing back in service and give it a new life.

I don't care for mags typically, always go for spoked wheels, and performance oriented sizes like these vintage race wheels I may use with some old DID shouldered alloy rims laced in Suzuki GS hubs. If no luck on an actual straight spoked Rickman hub, I plan on running these once I overcome the 11/16" axle to 20mm hub bearing/spacers i.d. issue with some machinework...
