Green, had it for 3 decades!! Lost quite a few CB 's along the way. DaveBarbier Really Old Timer Posts: 5, Not sure if it fits, but I've got a swing arm if you're interested. I'm a Really Old Timer Are you looking for a swingarm that is already set up for a mono shock or something you can convert? The Hawk is already mono but longer that your original stock length. The will be closer to what you have armbut will require fabrication of mono shock mount points.

Being shot out of a cannon will always be better than being squeezed out of a tube. That is why God made fast motorcycles, Bubba.Alright time for a bit of fun, cosmetic bolt ons don't really make a custom bike. If you really want something custom you have to do something a bit crazy. Well, redesigning the rear suspension with a high probability of failure is a good start, right? If you've been keeping up with my build, you know I went through the trouble to get functioning pod filters on my bike.

Theirs a time and a place for pod filters, and this build needed the room. With any luck, a shock will be sitting where the air box was. Fingers crossed. Here's the patient, stock with a dual shock setup on a subframe. In my opinion, a lot to be desired. I faced a lot of problems along the way. A first thought was too measure out the swing arm width and see if I could simply swap something in. Potential candidates such as XV and XT kept coming up short literally and my hope was wearing thin.

With this clearance nightmare I thought I can weld, why not just make my own from scratch? Well, after I sobered up I thought of the logistics nightmare of having the wheel track straight and insuring everything was in order.

This daunting task felt like it was impossible. Some closer measurements revealed how difficult this was going to be. All said and done I had a twelve inches, give or take, to fit a shock and a swing arm mount. Danger danger Will Robinson!

Turn back now was echoing through my head. These simple fitment measurements don't account for ANY load requirements that would have to be accounted for in the shock department and it was becoming apparent that I would need a shock that was very short. After many sleepless nights I spent wide eyed researching dry weights, lengths, and throw lengths I bit the bullet.

Pound for pound it matched on dry weights, gave me an albeit tight, but workable length. Had a decent stroke length. My only concern was the leverage angle would be different, and I had no plans for a dogbone setup. My options were running low and I felt like I had to make a choice so I could move forward.

Now that I had a potential shock I really needed to figure out a swing arm. Let me tell you, trying to obtain measurements of parts when they're not in your hands is nothing short of a nightmare. I can't tell you how many groups, forums and phone calls led to dead ends. I may have been running low on hope, but not persistence After all my research this is what I decided to do.Jonathan started this project around three years ago.

In his spare time, he customizes both cars and bikes, just for fun. His objective with this project was to achieve something different out of the CB and a monoshock setup was one of his own requirements. Since this is a pretty delicate job, Jonathan spent a lot of time constructing this part. The front is arear Together with the suspension and braking setup, Jonathan has all the ingredients for a super agile machine with super handling. In order to keep some of the original design in place, he mounted a beautiful set of 4 in 4 exhausts with chrome reverse cone mufflers.

Cleaning up the old triangle section also means that you have to reconsider the wiring. For this Jonathan could only think of one name: Motogadget. He completely rewired the machine with the M-unit V2 as the electrical heart. The triple tree also comes from Cognito Moto with an integrated Motoscope Mini. To give it a classic finish, he fitted an analog tachometer.

Other parts from the Motogadget catalog are m. Blaze discs indicators and m. Switch mini push buttons. But that seems well spent…!

Monoshock Conversion Tip: Spring Swap

What a piece of engineering, great! The Honda CB, also known as the worlds first super bike, remains a popular pick for custom bike builders. Great engine, good frame and pretty powerful specs. They're specialized in restoring Japanese motorcycles and just made this awesome CB….

A lot of the original parts are still on the bike and the changes are minor. This is an…. Your email address will not be published. We roll on our readers submissions, so if you want to show off your custom motorcycle: submit your brew!

It only takes a minute to sign up. I have a Bajaj Discover with dual suspension. I have seen some photos on Google of some people who have successfully done this conversion. What i found is that it could be adapted to the fork it currently has but I wanted to find out how the process would be.

I have done some research into the matter and not many mechanics around here seem to have the knowledge to do such a thing. I have tried looking into a more recent model that has the mono-shock but to buy the mono-shock and fork goes over budget. I opted into looking for other options. Can someone give a summary of what I would need to do to accomplish my goal of putting a mono-shock rear end on my motorcycle?

Currently your rear subframe is bossed and strengthened considerably as all of the absorbed energy from road undulations is transferred from your swingarm to the rear subframe, underneath your seat and tail section.

With a cantilever swingarm you will need a rear single shock mount point. You would need to build this and weld up your frame. If you are not well versed in frame technology and physics I would suggest you have this component created and installed by a professional frame craftsman. It would more than likely need to go where your current battery and air box are located. You would need to migrate the location of your battery and perhaps even remove your airbox.

If you remove your airbox you will need individual air cleaners for your carburetors. A re-jetting of your carburetors will also be in order if you do this. You can get a small racing battery and put it in your tail section. You will be very unhappy with this small battery the first time you try and start your motorcycle more than a few times and it doesn't work. Get used to push starting your bike from time to time. You will need a cantilever swingarm. If you do this, you may as well get a Honda SuperHawk single sided swingarm because, why not?

Your biggest issue is going to be the mount point on the frame though, followed by aligning your chain properly and shimming your front sprocket appropriately and possibly cutting the downtube on the left side of the bike so the chain has clearance. Migrate battery to tail section in order to have an open frame triangle without obstructions below the rider it's cafe style. If there is a monoshock solution for your bike where you can take all the pieces off a different model and modify the frame it will make it much easier.

You will still need to go through everything I've listed but if someone has done it before it certainly makes it quite a bit easier.

Active 3 years, 8 months ago. Viewed 4k times.Yes, I definitely noticed the deep sump! As for your HUB mods, I've seen something similar done with the single-sided-swingarm conversion with earlier 4-bolt drum hub, but what they did was make another piece for the pumpkin, the piece with the 3 bolt holes replaced with a 4-bolt version, or perhaps it was a bolt-in section which went inside the hub itself - IIRC, there was much to be done for spacing he hub at the bike's center-line, requiring a spacer to bump the hub to the left, IIRC But IMHO, you'd have to really enjoy the drum hub in question to have gone to this degree of trouble.

Plenty of options out there for a rear disc conversion at the same time. Now, I'm one to use a drum wherever I can get away with it. Wish to heck a drum would look better in the extra wide Akront rim for my "CBK0 Bol Bomber", but it would look like ass - I'd use this here 3. To tell the truth, I wish to heck I'd found two of 'em!

Anyway yeah, the disc type rear hub might have been just as simple of a conversion, using a "Front Hub Trick" type wheel, as was so often used for rear disc conversion on pre-'75 SOHC CBK's - or where the heavy-assed CBF1 rear disc hub was to be avoided - So many rims out there drilled for the Harley rear hubs, it's a mod that shaves costs elsewhere - Of course you'd need an alternative shaft-drive pumpkin, maybe even some of the more bizarre "parallelogram" rear suspension - which doesn't sound like such a bad thing, albeit the frame mods for the monoshock rear end might be a heck of a lot more complicated.

ANYWAY yeah, this type of rear drum would make for a great match to another drum up front, or an early style dual-disc front end, maybe even a single disc on a smaller or de-tuned - IMHO, the single-sided-swingarm doesn't necessarily match as "period-correct" to the drum hubs, just as with the wider flat-profile Akront rim and my own drum.

IMHO the most tasteful thing to do, is shoot for the modern upgrade parts which best emulate the period-correct race type works-spec parts, with oversized outer disc rings on the original 8-rivet carriers Metalgear Australia and "Robtools" on eBay, both making some cool rebuild kits for fixed composite discs - Ideally with original calipers spaced differently with alternative caliper hangers - what I'M trying to do here, is use the most period-correct RIMS to go with all that, 'cause a lot of the newer stuff just doesn't have the same look to 'em, they seem like they're just milled from billet with a CNC laser cheese-slicer.

Perhaps with some added DIY under-bracing to the swinger itself? So something like THAT makes sense to have the single-sided-swingarm with a drum. Perhaps some type of quick-change front end, with calipers that don't get in the way of a front wheel removal, maybe even the quick-release axle clamps or spindle etc.

THAT might pair well with the single-sided-swinger. Then again, I dunno about using an early version of which especially the more spindly versions of which, on a '70s-'80s Endurance racer, when even those street-bikes which used the tech didn't race with it - plenty of first-gen VFR series as opposed to VF-R Honda V-fours, went with a conventional swinger for their Superbike racers I'm all for a "retro-fried" version of more modern stuff.

As opposed to a "modernized classic", if you know what I mean. Just make sure you lace it to a decent period-correct racing rim. The "Super-Akront" 3. I don't know whether there was ever a tube like that for 18" rims, though it would certainly be cool - might limit one's choices for a lightweight racing tube though, leaving you with only heavy-weight tubes? But yeah, they're not only VERY light for their size, they're mondo cool for mid-'70s race-bikes, some very rare Unobtainium stuff - Far more common in 16" though.

And an 18"-er on my next DOHC-4, a cc stock-tuned bike "featherweight" for my daughter. I friggin' LOVE these rims - They've got such a beautiful look with a big drum hub, the drop-center profile giving even shorter spokes than otherwise If only one could ADD something in there?

As for finding a decent vintage style TIRE in the appropriate size, you're on your own!

Please list any modifications that are needed to get them to fit. Yeah I know about those with dual shocks I was just wondering what all newer swingers with single shocks would fit without too much fabbing. If were starting a thread I thought I'd add my swap. I can measure tom if you like.

I just bought a 77 KZ and I was thinking about changing out the front end for more stopping power. I can get an 86 Kawasaki ninja for a few hundred bucks but I'm not sure if the steering stems match up.

I'm also thinking about changing the swing arm out too and taking the monoshock suspension and suspension from the ninja. You think it would be a good purchase? Index of Forums Recent Topics Search.

Has anyone had a problem with the clevis on the bottom of the master cylinder push rod hitting the swingarm? CB mutt KZ You need to give up! Then send me the Suki swingarm. Anyway, you can run a die down the threaded rod, make more threads and cut down the length to shorten it.

It would be more polite to start your own thread rather than hijacking this one, but to answer your questions,the front end is not such a big deal, you'll need to swap the kz stem into the ninja triple clamp. The monoshock is doable, but requires a good bit of fabrication work.
