Topic: CB 750 Rear Sets

[Chester345]

Hi all, looking for some pics or ideas for rear sets.  I've been digging thru the forums and now am wondering if anyone out there has fabricated anything themselves they are particularly proud of?

I've considered using the Dennis Kirk frame clamps with some late 90's CBR front sets and cutting the passenger peg part of the frame completely off.  Also considered some universal rear sets but I'd have to fab more linkage and those dang things are expensive.

Buddy of mine, good welder, wants to fab something up actually using the rear stock peg holes and making something to push back up on the piston for the right side with a new lever.  The left side is simpler imho, I'll just model what we do on the right.

Any ideas or pics of something that hasn't been posted already would be greatly appreciated!  I'm still in the thinking part of it...

Thanks!

These where made for my 550, but the concept might work on the 750 as well.

Very nice!  You go the whole 9 yards with fabrication!

I would love to do something like that... (translate, I'd love to have the tools to build that!)

Here's the brake side

[Chester345]

That's nice, I like how you re-used a lot of the stock mechanism.

Did you machine that bracket yourself?

Edit:  I've come back to this about 10 times to drool over Steve F's peg mount, dang that thing is shiny!

man thats purty

Okay, has anyone found arms from a stock bike that will fit the CB750 shifter shaft and the standard mechanical brake linkage shaft?  I checked on the brake side for a Tarozzi and they wanted $80 just for the aluminum splined arm!  Anybody found one that will work other than cutting and welding a stock brake pedal arm?  Thanks!  RR

Ricky Racer,

     I'm pretty sure almost any Honda (as well as other Japanese brands) shifter arm will fit on the CB750 shifter splines.

     I went to the Honda dealer and asked if I could look in their parts for a shorter shifter arm.  They let me look in their bins, and I ended up using a Z-50(minibike) shifter, mounted backwards for an upside-down shift pattern.  It was very cheap.

     I would take your shifter off and to the parts counter with you, along with a measurement of how long you need the new one to be, and ask the same thing.  Maybe ask the parts guy if you can buy him a soda for his trouble, too.

     I'm planning my rearsets for my current project, and for the brake side, the footpeg will mount just aft of the brake pedal pivot.  I'll either shorten the brake pedal and the brake rod arm on the back side of the brake pedal shaft, or cut the brake pedal and drill it to use it as part of a linkage.

i still have to get around to making mounts and linkages for these, but here are mine in basic form. 100 bonus points to whomever can guess where i stole the design from...

Here's the shifter side.  I machined all the stuff myself, using mostly scrap that was laying around.  I made my own splined parts too

[Steve F]

This is the brake splined part that I made, using the stock splined shaft, which was shortened by about an inch. (sorry about the blurry pic)

Hmm interested in making me a set for some $? I live in chicagoland. I don't have the resources to make anything myself and have been contemplating a late model bike set modified but honestly don't feel I have the know-how to do that sort of thing. I'm a grease monkey, not an engineer. Ha!

[SOHC4 Cafe Racer Fan]

Meeee, too. 

[Flying J]

I bought some R6 parts to build mine but if the price is right id be intrested too.

[d3buttz]

hey guys-i cut off the passenger pegs and i took a 1/4 inch flat plate steel, welded up both sides and drilled the i.d. for the tarzzozzi rear sets- they were pretty cheap(160$ i think) and i havent had any problems since-but it took ALOT of planning to have it comfortable,have the kick starter clear, have the brake still work-luckily the honda 550 brake arm on the wheel can be flipped to the top w/no mods.  my advice is to keep in mind all your variables-i was lucky after i was done that the original brake light switch and switch frame mount still worked in-line on my rear sets.

[billybobobrain]

Hey that’s exactly what I’m in the middle of right now, looks great. Glad to know I’m not a kook.

[SOHC4 Cafe Racer Fan]

debuttz,

Very nice looking!  What year/model CB750 do you have?

[MCRider]

debuttz,

Tis a 550.

And I agree.

Question, by putting the brake arm on top you have switched the leading shoe/trailing shoe. I don't think it'll make a difference but have you tried the brakes out yet?

Someone else here with expereince probably knows.

[bwaller]

The shoes are indentical anyway, but the leverage will be reduced. Then again it's only a rear brake!

[MCRider]

That's right my bad, the leading shoe is still the leading shoe. And the leverage issue may be for the good. Won't know till he tries it.

[d3buttz]

the brake arm lever on the wheel works like a cam-as you brake the lope becomes wider and pushes the pads out.  the lope is the same when yuo flip it 180'- the splines on the shaft have 1 wide spline that doent allow you to just flip the lever externally-but its super simple to do.  Also  the leverage is pretty good-i can lock up the wheel if i get on it pretty hard-not as great as stock tho, that arm stock is pretty long.ive had a couple of jerks oncoming make a fugazi left at intersections on me and im still here! 

i recommend using the stock rod that connects the lever to the arm-its made of a hard steel with a high tensile strength.   

also the nice part of using the tarzzozies is you can get the sets with folding pegs(what i have) and it makes it Alot easier to plan the placement in respect to the kick starter. flip and kick!

Man, I've got nothin.  I was goin over everything I could think of, Tron to Judge Dredd.  I do like the shape though, adds some artistic flare!

Thanks for all the replies and pics, awesome work, really!

[papp101]

Any updates on this? Love the build!

[Flying J]

I see a lot of K's with rearsets but the F bikes are a little more difficult with the rear disk and all the crap bolted to the side. Here was my solution.

[Chester345]

Ok, minor update.  I bought a pair of pegs from an 02 Honda 954RR and am going that route.  I seriously considered cutting some aluminum and building my own bracket to hold pegs, my buddy was all gung-ho to try that, but I think I'll like this look a lot.



The pic is just temp atm, I know the bolts are backwards, it's just a mock up.   I'll be securing it more tonite.  I used the Dennis Kirk frame clamp for the top, and will be welding a nut to the frame for the bottom of the bracket.  A note on those DK clamps, wow, for the 7/8" ones, they are a serious piece of metal.  Before I got them, I was wondering if they would be secure enough, I don't wonder any longer.

I need to score a longer rear brake line, and I'll be doing something creative with the side cover where it will now meet the top of the bracket and piston assembly.

The rear peg brackets have been cut off and ground down, I'll be sanding smooth and painting before long.

I sifted thru a lot of those posts and ideas before I started, there were some really good ones, and a few scary.  The last thing that led me away from cutting some plate aluminum and/or Tarozzi's or the like, was price.

I may end up going with a plate cut bracket of some sort if I really don't like the placement of the peg when I'm done.  I'm pretty comfortable with a more aggressive stance all in all, and that's where they are sitting right now, high.

More soon, thanks all for the ideas!

Here's a shot of my brake side, the rearsets are from a '03 Hayabusa:



I cheated on the brake side, I couldn't be bothered figuring out how to make it work with the drum so fitted a disc rear wheel and just used the Suzuki MC.

On the shifter side, the only problem I had was with the joints on the link rod, Suzuki fit the l/h threaded joint to the pedal, Honda fit theirs to the gearbox arm

If anyone want's any better shots just say andI'll post them as soon as I get home

Ricky Racer,

Pretty much all Hondas have the same spline on the gearbox shifter shaft, but the actual arms come in a massive variety of lengths. My bike is currently fitted with one from a 2001 Blackbird

Suzuki and Kawasaki (can't speak for Yam) use the same diameter shaft, but with less splines around the circumference, you can hammer them on, but that's just rough    Honda and Kawasaki also use plate steel link rods, which rust, Suzuki and Yamaha use stainless steel for theirs. If you have a good enough breaker locally, you can definitely find one the right length to suit your set-up
