SocoMoto: 1976 Honda CB550 GSXR Front End Swap

[@moneeb343]

This is an incredible video. You don't space out on explanations while lots of videos do, please never change! Keep these explanations and math and specifics in! It's wonderful!

[@ekkachailee2200]

Great videos! Great build. This is something I've been looking to build too.

[@BillCompo]

Once rebuilt the old CB550 forks are a great upgrade for CB350's and CB360's .

[@themightydash1714]

Damn them calipers sit close to the spokes! makes for an amazing looking bit of kit though!

[@johntran8207]

love your vids...keep em coming!

[@similac95]

Couldn't you just not install the bearing spacers which would allow the axle nut and axle shoulder to go further into the hub? Great video! Thanks for the information.

[@CDeWigDrift]

ok I've made some progress. slow and steady wins the race. so what did you do for the rear wheel. just leave it. the harley front rim is wider than the rear. Is that ok with appropriate tire sizes to accommodate. were there any adverse handling issues? Did you finish your bike. you never posted up anything else about it?

[@steverice7546]

Very informative video, so thanks. Did you need to put shims or spacers between the rim/hub and the rotors to gain space for the calipers to clear the spokes?

[@sebastiengauthier6528]

Hi . I have a cb 650 1980 and I would like to instal a gsxr fork with the gsxr wheel . will any year of the gsxr fork fit and is there any other kind of fork fit honda, yamaha or kawasaki ? Thank you

[@Jan1331xo]

Hi brill video just wondering what rear wheel did you used?? Is it the same Harley model?? Thx alot.

[@ralphmandiesel3572]

Does drilling into the brake rotor weaken it?

[@SeSmith405]

How did you center the spacer on there?

[@albertinosa]

Great! Is the gsx stem right for the cb neck or did you do the mod?

[@logisticaautomotriz5313]

what is the distance between to rotors?(rotor to rotor inside or outside)

[@ralphmandiesel3572]

Thank you! This video was super helpful

[@elliott-nk7is]

Nice video. I have '76 750 and will be using an '08 gsx r600 fork. My question, why not machine down the bearing spacers to match the axle?

[@SocoMoto707]

the axle sits on the bearing and not the bearing spacers. the bearing spacers will just space the bearings out to the edge of the wheel hub

[@travisbailey4470]

Hey, nice work. Do you know what front axle that is? I have a 09 gsxr front end that has a different front axle. It looks like a 600 axle appears similar to what you are using. Any thoughts? Thanks

[@SocoMoto707]

the front axle is from a 2004. you have a different axle in the sense that you have a spacer, a lock nut and an axle. mine is just the axle and lock nut. In the 2004 versions, the lock nut and the spacer are the same. basically, you are going to need to add another spacer to it. see this thread for how to do it: forums.sohc4.net/index.php?topic=63784.0 do everything that i did in my video and add in the axle portion of the tread above.

[@maxkremer9774]

got the wheel, got the forks. can't find those caliper spacers anywhere... where do I get them?

[@SocoMoto707]

you can get them on ebay or amazon

[@maxkremer9774]

+SocoMoto707 Hey thanks man. I tried. Can you suggest what to look for? I tried "caliper spacers" - nothing on Amazon. On ebay I found Brembo specific ones only :(

[@SocoMoto707]

if you have a drill press and bandsaw, then you can make you own. spacers are nothing more than a piece of steel rod with a hole in it. you can just buy a steel or aluminum rod, cut it to 10mm and drill a hole that matches your bolt diameter. im sure if you went to a metal fab shop, then can make you some spacers for less than $20

[@maxkremer9774]

SocoMoto707 Thanks. For those reading this and trying to do the same conversion the right spacers should ideally have collar that fits the caliper. I found mine on ebay from Taiwan for $20

[@artemknaus]

Socomoto, what's the width of the HD hub?THX

[@robdstewart84]

Do you have part number for wheel bearing spacers from HD?

[@codyportz8107]

you have any knowledge on the cb900 and which front ends fit best with it? Like a GSXR front end or a CBR?

[@The-vi3iu]

Hey man great information and something a lot of people are doing but for a lot more money. I love the idea! Did you find that just simply switching out the neck bearings allowed you to swap that set of forks onto the cb550? If you did can you please share what you've learned or how you found was the easiest way to do that. Thanks again for all your help. Pretty creative!

[@The-vi3iu]

@socomoto707- any updates on this?

[@PointlessMiracle]

look up cognitomoto, they're using a lot of these gsxr front ends on old bikes like these. The CB500 and 550 have a perfect length STEM, so you can just put in new neck bearings and its done. Although I think you don't want those ugly gsxr wheels on your cb550.. That's why I'm watching this video..

[@AJBALOO]

What spoked wheel will you be using for the rear?

[@shawmaster97]

how much did the harley wheel run you

[@Lvelds]

Been a while since you posted, but you wouldn't know the PN of the Harley bearing shim would ya?

[@SocoMoto707]

i think its #43903-08

[@mehaylek]

Great job, SocoMoto707 Two questions: 1. I couldn't see a seal out there, did you install it after? Cuz it seems like so little room left.. 2. 1 inch is 25.4 mm. And you replace it with 25 mm bearings. Do these .4 mm matter that much here? Thanks!

[@SocoMoto707]

1) i didnt show the seals in the video because i felt like they would block the installations of the bearing. the seals fit in fine because they dont need much room inside the hub to protect the bearing. 2) The .4mm does not matter much in there. the bearing fit pretty snug inside the hub and take some pounding with a "dead blow" hammer to get them in. make sure you dont use a regular hammer.. .use a plastic hammer(with the sand inside) or a wooden hammer to install the bearings.

[@TheSammymax]

definitely not enough info or details in this video.. ... . .. ..... lol. thanks man, Im glad i took drafting when i was in 7th and 8th grade!

[@TheCogleymike]

Hey pal. See you didn't install the rubber seals? Also is that bearing sleeve the stick Harley one from that wheel? I'm doing this conversion now

[@SocoMoto707]

yeah, i didnt put in the seals because i didnt want to block anything in the video. the bearing sleeve is a stock harley sleeve, but you might have to cut it depending on the harley part number you get

[@ayeitsjayoo]

hey,my question is..I have a 1976 cb750f super sport,and I have a 2000 yamaha r1 with dual disc brake.so can I just put the yamaha fork on my cb760f?

[@SocoMoto707]

not sure.. but you need to check the stem length. if its too long, then you need to cut it and re-thread it. also check out all balls racing to see if they have a bearing kit that will fit.

[@CDeWigDrift]

i went to a local harley shop and asked about the street bob wheels and no one could find a 07 street bob wheel with dual front brakes. Did you drill and tap holes for the other side or was the wheel setup for a disc on both sides. I have a 74 550 and 01-02 gsxr 1000 front end im piecing together and im down to the wheel. any help would be greatly appreciated.

[@SocoMoto707]

ok, the problems is that you are looking for a bike with dual disc brakes. most harleys dont have dual, just single disc brakes. If you look at a harley hub, it will have a single disc on one side and on the other side it will have a cover on it. remove the cover and you can mount a second disc.

[@anthony_sasquatch8056]

SocoMoto707 that's not really true! Sportster 1200s came with them and dyna super glide sports have dual disc aka fxdx

[@matthiassteck8219]

Hey. Thanks for the video, was a great help and inspiration. Where did you get the spacers for the calipers from? Also, were you able to use stock bolts?Thx, Matty

[@SocoMoto707]

i got the spacers off ebay.. just typed in 10mm caliper spacers. i had to get longer bolts because of the spacers

[@ayeitsjayoo]

cb750f.?

[@Tews-x5o]

Just awesome! I am doing the same set up. Only if I could send you the axle to machine. I would pay you if you are willing.

[@SocoMoto707]

honestly, it might not be worth it with shipping and the cost for me to do it. i think if you took it to a mechanic, it should cost around $50

[@lltew1]

SocoMoto...I guess I don't understand why you changed to a smaller wheel bearing and used a spacer to take up the same amount of space as the one inch bearing. Great Video!!

[@SocoMoto707]

lltew1 i think the harley hub comes with a 1in wheel bearing which is pretty much equal to 25mm... But i just wanted to keep things exact so i removed the 1'' and replaced it with a 25mm bearing. all 25mm bearings come standard with that width so i had to use a spacer.

[@SocoMoto707]

i could have used the 1'' bearing(25mm=1''), but i wanted to show how to use 25mm bearings

[@catalinaoutfitters]

What are the dimensions of the bearing sleeve?

[@SocoMoto707]

its a harley 1'' bearing sleeve that i milled down to about 4.145'' long

[@bettercalljeff2453]

great vid and info. Thanks

[@miller73179]

hell yeah you are very precise!! i like it

[@krystalsmith4022]

#goodjobmarc

[@domino2205]

nice video but not to sound like a troll why go to all the trouble and use a Harley wheel and mickey mouse making it work? why not use the GSXT wheel and brakes? Well not a clue why you went to such lengths when the solution is simple

[@mjoves]

domino2205 there’s no Mickey mousing anything together.. it all works.. plus if i can make it work then why not do it.. I’m not sure what a gsxt bike is, but if you are referring to a gsxr wheel then it looks horrible on these bikes and inverted forks with spoke wheels looks amazing
