I have a 1962 G12 CSR Matchless Monarch. Probably a princess. I have advertised this for sale off and on for several years. Ebay a couple of times, Craigslist, this forum, and at meets/shows with a sign. I got an offer of $3500 a couple of years ago on Ebay, which I declined. At the time, I thought I could get more. I couldn’t. I got a second offer last year for $2500 through this forum, which I also declined. I understand that its value is hurt by its “non-standard” trim. I have since removed the regulator/rectifier and kickstart lever. So it is also no longer operable. It also hasn't been started in at least 3 years and not ridden for longer. So it is no longer for sale. I have decided to keep it and further modify it.
The parts of this bike are clearly worth more than the whole. I recently saw a decent complete set of forks get bid up to and sell on Ebay for $605. First set I ever saw on there. Came up when I was looking at Norton
fork parts. I sold a good fuel tank a few years ago for $500. I have also already sold off some other original parts. I could break it down and easily sell off some of the more marketable parts, but that would require considerable effort on my part for a few dollars. So that’s out.
In my opinion, this is not a good road bike. It shakes like hell. The performance is a little underwhelming and it’s a bit fragile. And the front brake is dreadful. Grab a handful of lever, and you get the sensation of slowing down.
That being said, I find this bike interesting. That’s why I bought it. At any gathering of motorcycles, it’s almost always the only one there. I installed an electronic ignition and it was always easy to start and fairly dependable. So that makes it fun for tooling around the campground or rally site. Around the neighborhood and at the few and far between events are about the only time I ride any of my bikes anymore.
So I have decided to mount Norton
forks and the front wheel from my Commando
on it. But this will be a budget build. And the budget will be $0. I want to sell off the Matchless front wheel, fender, and forks to cover the cost of the pieces for the Norton
forks that I don’t have. After all, AMC did it with the N15 and G15. If that lot can figure out how, I should be able to also. Give me something to do in my old age.
Research on this forum and links posted here has informed me aplenty about Roadholder forks. I found this on the forum about the G15 and N15 hybrids:
“All these machines used a new frame similar to the G.12 C.S. duplex type with bolt on rear subframe but were fitted with a redesigned malleable steel headstock machined to accept Norton
forks and front wheel.”
What will be needed to adapt the Atlas yokes to the neck will be unknown until I remove the forks from the Matchless. This required some planning because the bike will be impossible to move around with no forks. And once the deed is done, it shan’t be undone and the bike could sit like that for an extended time as my interest ebbs and flows. I have now moved it to a suitable place and am prepped for surgery.
Here is what I have from my Commando
Bushings and seals
I will probably purchase stanchions and dampers new. So I believe I have a choice of G15 or Commando
components. Here’s what I can think of that I need:
Atlas 7-3/8” yokes – bought for $125
Bearing nut, 26tpi
Crown nut, 26tpi
Stanchion top nuts
Stanchion top nut washers
I have taken some crude measurements of the Matchless and the Commando
. Measurements were taken with each bike on both wheels unloaded.
They are as follows:
Rake – 26 deg
Offset – 2-5/8”
Axle C/L to top of neck – 27-5/16”
Neck length – 6-1/4”
Top of neck to top of stanchion -1-1/8”Norton Commando
Rake – 27 deg
Offset – 1-7/8”
Axle C/L to top of neck – 26-1/2”
Neck length – 6-3/8”
Top of neck to top of stanchion -1-7/8”
Here she is in her non-standard glory before surgery
Here is what I have. Saw a brake assembly sell on Ebay a couple of days ago for $230.
