Larger rotor with Brembo 4 pot caliper

sorry i did not mean it as a hard and fast rule as there are plenty of 65mm calipers that have only 2 pads, but rather that the 2 pad 40mm units should be the cheapest as most people "upgrade" to the 65mm 4 pad oem units. Those on ebay will be more $$$.

check this out too, brembo makes a factory racing kit

also waiting for someone to try the brembo 15RCS master

Nassert beet of japan makes kits but they are far from cheap and from what the one guy on here was saying, they don't make a 320mm rotor its either a 310 or a 300, i can't remember. perhaps he will chime in here, the guy who posted a few posts ago from asia can't remember his name

Yes the Brembo route can be expensive

I have also seen Tokico & Nissin done

Yes Nassert Beet does a 310mm

[mania]

Would be nice to get a line on these

Made by KTC in Indonesia they are 4 piston radial caliper with the mounts
to fit 290 or 320 rotors on the Ninja
( You just use those spacers to space the caliper back on the larger rotors )

But try as I might I have not been able to order them
It is very hard to work with Indonesia in my experience

[mgentz]

Asia has all the cool toys for the ninja....

yeah but for me at least its not the disc size its the caliper feel/flex that sucks lol

Just sent sub an email, but here you go. Let me know what you think.

[ForceofWill]

Looking good. Can't wait to see it finished up and installed.

I see three. For sale?

[Bigballsofpaint]

2 are scrap, last one was good. I can order more material if a few people want one - now that the program and work shifts are done they will all come out good.

Cool, still have to give it an official test run yet though, maybe hold off on making any till I give it a go just to play it safe

When you sending it? We can discus the finer details via PM

EDIT: just saw your first post, checking email now

once the install and testing is completed, maybe a group buy or something?

Looks like nice work to me.

[Bigballsofpaint]

Ill be sending it to Joe on sat, so we should know if its good or not within a week, he seems ready to install it and get on the road.

Sharky, if i make this it will only be for a group buy. Its not worth it for me to only make 1 or 2 since i dont get many windows of open machine time. If i do even get any, otherwise ill have to do it on a saterday.

If we have any ninjette powdercoaters, i wouldnt mind teaming up with them if their price is reasonable, thats IF people want them power coated...

[subxero]

^ powder coat would be kick ass and a nice finishing touch

[Vintage Smoke]

Skip the powder coating as it will be a "built up" finish. You would have to mask off any bolt holes and especially any mating surfaces as any powder coating between mounting surfaces will eventually squish down and result in a lose bracket. Also..the cost would be for each part.

Look into anodizing. With anodizing there is usually a flat "basket charge" as in however many pieces you can fit into the basket to dip them in the solution is one flat charge. Most of the billet parts you see on the market today (levers, rear sets, swingarm spools, etc) are anodized.

[Bigballsofpaint]

We do a lot of hardcoat annodize on our products here. I figured powdercoat only because there arent any threaded holes, the through holes already have a decent tolerance in them so i didnt see what being an issue. Didnt think of mating surfaces breaking down though. I think leaving them bare and using a rattle can may be the best bet haha

[crazymadbastard]

I have a powder coat setup, nothing fancy its a harbor freight setup you are welcome to use in Ct.

[genosr1]

very nice work

[subxero]

Got the bracket today, looks great. I am going to try and find some time tonight to at least bolt things up and check alignment all that jazz, if all that looks good i should get some time tomorrow to hook up my brake lines, bleed 'em and anything else taken care of and i should be good to give them a road test some time this week weather pending.

Gonna be interesting either way, i have changed a lot of things since i have ridden it last so i won't be able to attribute any of the changes in feel to any particular mechanical change. Oh well

[mgentz]

Hope all goes well.

[verboten1]

Dang looks nice, I could be interested in that!

[subxero]

Everything lines up seemingly perfect, but I was unable to bolt it up last night as my 2 bolts I used for my prototype were to long as my prototype was thicker in that area.

I need to get 2 bolts today, or at least a new hacksaw blade so I can shorten the ones I have before I can completely bolt it up. But bolting it to the caliper then partially threading the bolts to attach to the fork everything looks really good. After I bolt it up today and bleed everything blah blah, I can check the foot print on the rotor but it looks pretty stellar! Hopefully I can find a few minutes after work today to spend tinkering. I have time at night but no light electricity in my shed so it makes things interesting.

[sharky nrk]

sounds promising

[subxero]

Latest up date. Everything bolted up nice and tight and there seems to be no problems what so ever. With the pads loose and rotating the wheel (front lifted) there was no sound what so ever so clearance all around. Hooked up the lines, started bleeding. Still in the process of bleeding them. The brake lever feels a little light and mushy still but again i need to bleed a bit more but i also haven't ridden it in months so i can't remember what it used to feel like. Did a quick foot print check and it looks perfect!!

I hope to finish it all up tomorrow and maybe ride it on Thursday or Friday but we get rain pretty much ever day so who knows. Ill snag a pic or two tonight but my camera phone blows and my digital is broken.

[Bigballsofpaint]

Glad to hear it man, good job with those dimensions haha

looked things over really close. Again it seems perfectly fine but i would definitely change just one thing to give a little bit more clearance.

Couldn't be more happy with bolt placement... it is 100% perfect!! Foot print is perfect!

But I would make the thicker parts of the bracket where the bolts for the caliper are just a hair thicker. 0.02 thicker to be exact. I can't remember the number i settled on in the end. I think it was either 0.58" thick or 0.59" but either way. If you make any more add 0.02" to that. This will center the rotor just a little bit better in the caliper. On the inside side of mine there is very little clearance between the rotor and the cast guide of the caliper. On the outside there is more than enough. So making that part of bracket just a little thicker would transfer some of the clearance from the outside to the inside.

I will admit this is the one dimension i kind of had to take a guess at. It was an educated guess though. An accurate measurement was tough to get.

Great job, thanks again for setting this up and doing it. I will post some ****** pictures tomorrow

[Bigballsofpaint]

Ya you had it at .58, .60 wouldnt be a problem

[sharky nrk]

sweetness, waiting for pics

[subxero]

as promised, some crappy pictures. I hope to get a new digital camera before this weekend so I will update with better pics next week.

These are taken at night, with no light on my busted camera phone.

I will probably look for some fancy bolts to clean it up a little bit. Maybe some gold Ti race spec bolts or even just steel race spec, IDK? something, anything will look better than just regular old bolts

Still need a road test but should be non issue. Might have to go to larger master cylinder if I don't like feel of brakes. I need to go feel some brakes on some nicer bikes first though.

Now that this is pretty much GTG I can maybe put together a DIY with everything laid out. Pretty easy really.

[Bigballsofpaint]

Glad that clearance on the left worked, it was my only worry. Now just grab some spraypaint and clearcoat that sucker!

yeah there was lots of room.

I need to check the thread pitch again on the bolts for the caliper I can't remember what it is off the top of my head. Maybe I can find it on the web. For some reason I think it is 1.0 and that website does not offer any M10 in the length needed in the 1.0 pitch.

Ill get all this info for the DIY together

EDIT:

Some guy on the web says mounting bolts are m10 1.25, that makes sense, I think I was getting this confused with the banjo bolt which is m10 1.00

M10x1.25 will be easier to find.

[Bigballsofpaint]

SO should i order more material, GB anyone?

[ForceofWill]

If you pumped several out what do you think they'd cost? Still need sub to get a parts list he used to.

I'd be down tho.
