Actually our front braking system is the same as the GSXR1000 of the '06 variety. That was the claim to fame by Suzuki when they brought the bike out. I will say good luck on your search. It is a known fact that Suzuki's sportbikes in general have the best braking right out of the crate than the other 3 brands. So, you might find it hard to beat. Also, if you can lock up the front wheel then there is no issue. If you can not, then bleed the brakes or change pads. You can also change rotor/pad combinations to get a better feel. I bet what you think is a braking issue is actually a suspension issue. Our front forks have no adjustability and are terribly soft. I can bottom out the forks on a hard brake which makes it feel like it is not braking that well.

FYI This is for an M90 not a 109.

 

Then they buy these brackets http://www.svracingparts.com/store/#!/~/product/category=484220&id=7777413

Did you ever buy those brackets? I bought them a while back while I was trying to modify the M109R front rim to fit the M90...I thought I had tossed them out, but I just came across them while I was cleaning out the garage while packing up to move.

Anyways, if you haven't bought them and want them...they're yours.

 

I was just about to order them so if you have them I would love them. I really appreciate it. i think between you and I we have tried more crazy **** that may or may not work than anyone else.

 

I have finally gotten around to starting this project. I have it 90% done just waiting on some new longer bolts for the bracket. There are some adjustments that will need to be made to keep the brake pads from rubbing but I think I have figured that part out. The next step is putting in the new bolts and seeing how my modified SV 650 brackets hold up. I did take it out for some slow speed stops 30 mph and below and there is a lot more feel and more bite to the front brakes. I will post some pictures this weekend if I get the bolts in time. Hopefully this works out and holds up.

 

the only problem i have with the brakes is the rear i had a gsxr750 and i was finding that with those brakes i was some times lifting the rear wheel while braking i am not sure if you would like to do that with the 90 could get a little hairy. and what about the extra dive you would get with better brakes i have pics of the 90 and gsxr close and the gsxr has alot more travel than the 90. hate to see someone lock it up and side down the road i also found that i had better braking when i put on the braided lines

 

Yes the brakes are more powerful but you have much more feel so I should be able to modulate the brakes. The M109's have the newer GSXR calipers on them. Guys have been doing this upgrade on SV 650's for many years with no complications. The complications with our bikes will be that the actual brackets made for this are not an exact fit and even with my modification may rub a little or the modified brackets won't hold up. . As far as lifting the back end is the weight distribution, weight of the bike , riding position and longer wheelbase should take care of that. Manufacturers put less powerful brakes on cruisers in general than sport bikes to save money and they feel cruioser riders just don't need to stop as fast due to riding styles.

 

if you want the extra brakes get the 109 front end uses the same neck bearings as ours i bet they are the same size been trying to find out how much a second hand front would cost then you have the best of both worlds 3 piston calipers and the chance to put custom wheels front and back

 

edit ~ I just realized my response was to a combination of your posts regarding a front end swap. I decided to leave it mainly for clarification of what may be needed to tackle this modification.
------------------------------------------------------------------------------------------------------------------------------
I think the point you are missing is the fact that the forks for the M109R are a different diameter than the M90's forks, it is not an issue of just sliding the M109R forks on the M90. You would also need the upper and lower M109R triple tree to accommodate the larger diameter forks. Now you need the front M109R brake calipers because as we should all know by now, M109R front brake calipers are not compatible with the M90.

Now, just because both bike's steering bearings are the same diameter, that does not mean the steering stem from the M109R and the M90 are the same length. Same goes for the length of the forks...my gut instinct tells me the length of the M109R forks are going to be longer than the M90 forks.

I came to the conclusion years ago that if I wanted fancy aftermarket rims, the easiest and least expensive way to do it was to trade my M90 in towards an M109R.

 

Cost is the main factor not to go the M109 front end way. This experiment buying all the parts is around $300.00. If is doesn't work I can resell the rebuilt calipers and pads for for at least 100-maybe 150 and I am only out a few bucks. We will see in the next 30 days if it works.

 

has anyone really seen how much a second hand 109 front end would be there is more than likely guys in the usa with written off bikes that the forks would be good. i have tried here in aussie but no one seems to have a set

 

Just the forks are going on ebay for at least 600 up to 1200.

 

yes i realize that now that i found the sizes of the rotors the m90 centre is 67mm the bolt centres are 86mm.
the m109 centre is 100mm the bolt hole centres are 120 which puts the bolts outside the steel on the m90 rotor
now see you never posted any thing like that about the rotors what i would have done to fit the m109 rotors was simply taken the forks to a engineer place had the caliper brackets cut off and extended the distant needed to fit the m109 rotors and before you say that it wouldnt work i have a mate who is a welder and he said it could be done because its a upside down fork you dont have to worrie about war-page and if you control the heat right there wouldnt be any warp. and there is plenty of people around that have done this sort of thing with conventional forks and never had a problem. and there is alot of 290mm rotors that fit other bikes i bet there would be one to suit something with the 100mm centre
the cost for cutting the caliper brackets off and extending them would be around the $450 mark and if you had a set of wrecked forks off the 109 you could have them welded on giving the better calipers

 

Your measurements of the centers of both rotors is way off...I am not even sure how you came up with those measurements. I think I was pretty clear in my original post that the size of the center of both rotors don't come anywhere close to matching.

As far as cutting off the caliper brackets...how would you even do that without wrecking the fork? How about, like I mentioned in my original post, just having caliper relocation brackets machined that would offset the M90 calipers to accommodate the M109R's 310mm rotors?

I get it, you are trying to brainstorm, but in reality there are 3 solutions here...swap out the entire front end with an M109R, have caliper extension brackets machined or buy an M109R. I apologize to amvince for totally hijacking his thread! :joke:

 

ok amvince i have been doing research into this and the reason deputy couldnt get the the original tokica calipers to fit the sv adapter plate is because you need to have the gsxr600 or gsxr750 tokica calipers the holes are spaced wider than the m90 calipers am i right deputy. then if you get the dl1000 or sv1000 rotors they have the same spacing as the m90 rotors but are 310mm that will give you all the braking power you would want

 

I am a little confused. Deputy was trying to use the M109 brakes and wheels which have more modern "floating calipers." The SV 650 brakes and rotors are the same as ours what. On the SV 650 top use the older style GSXR 600/ 750 calipers it requires this product.

http://www.svracingparts.com/store/#!/Caliper-Adapter-Brackets/c/484220/offset=0&sort=normal

The issue is the bottom of our forks are cut a little different so I needed to cut part of the bracket to fit on our forks. The holes are spaced the same though. Once I cut the brackets and put on the calipers there is was a lot drag on the brakes so I added washers as spacers and a little longer bolt and now I am getting much less drag but still a little. I am going to see if this goes away with a little riding. The other concern I have is how will the modified bracket hold up so I will be looking at that all the time. If all goes well I will have much better brakes. If not I guess I will just put the old calipers back on and nothing lost but a little money and time. Here is what the SV 650 forks look like with the brake swap.

http://www.svrider.com/forum/showthread.php?t=153787

 

its looking more likely that those brackets for the sv650 wont work because the sv has offset rotors thats why the brakes are draging heres some reading
After making some adapter plates to fit nissin calipers onto my stock 1st gen forks, I discovered the 310mm rotors from the RF900 '94-'98 are a direct bolt on replacement for the 290mm sv650 rotors. That is, ID 64mm, pcd 86, 19.5 offset. This would make for a pretty awesome set of stoppers!
Obviously with correct adapter plates.
Has anyone ever heard of this being done?
Also, in my travels, it seems the SV1000 310mm, and TL1000 320mm rotors are the same specs as 2nd gen SV650 rotors.

heres some other brake rotor upgade with 310mm rotors the point here is the rotors donot look offset and tell you what rotors they are

the 19" DL1000 is both a versatile and durable wheel that can be used in a varity of applications, and the swap to the 19" Versys front using the stock Showa forks and OEM Versys calipers is just one. the Versys 19" is VERY easy, i've had the recipe posted for several years now, no ninja machinist skills needed to accomplish this swap. you do not need expensive spoked wheels to improve to the Versys performance on unpaved roads, just find a cheap DL wheel and swap it in. Finding a used wheel at an acceptable price is by far the hardest aspect of the swap, once i posted the swap info, the supply of cheap used DL1000 wheels decreased almost overnight.

the rotors used are Suzuki rotors that start their OEM life at 310mm and have the same rotor bolt pattern as the DL1000 wheel. besides the obvious DL1000 rotors, the DL650, and SV1000 also fit. the SV650 is 290mm and won't work here, but will work for other swaps. there may be other model 310mm rotors that share the same bolt pattern, the main objective is to find an inexpensive set.



from the left: SV1000 310mm, DL650 310mm turned to the Versys 300mm, SV650 290mm.

i'm still using the DL1000 wheel on my DRZ400S suspended Versys with a 310mm SV1000 rotor and OEM Versys caliper, like i said, a versatile wheel. i have a 4 pot caliper, but haven't fabbed an adapter yet, the bike stops very well as is.

 

so i shot a email to the svracing and they said that they donot make brackets to fit 310mm rotors but the 290 mm ones are fine but it looks like those brackets are made for offset rotors i think the 290mm sv rotors are 19deg offset so yes you will need spacers too reset the calipers. but there is no reason why brackets cant be fabricated too fit the 109 rim and rotors just need to find a shop or you can make them yourself racers have been doing this stuff for a long time and they need better brakes than what we use on the street i will be looking into this when i find a new job and not working par-time and getting stuff all money

 

I just used a couple of washers for spacers on the bolt that attaches the calipers to push them in a little. I will post some pictures as soon as I can.

 

Dep sorry it took so long to take the pictures. Took the bike out for about 30 minutes today. The noise seems to be subsiding with every mile and I really hope this works and holds up. The bike stops so much better than it did before.

 

the noise is probably your pads wearing down on 1 side so those brackets dont line up where the fork bolt holes are meaning the calipers dont sit in line where the originals sat. that would be because the sv rotors are offset that little bit you really should take a measurement where the original calipers sat and try and get the new ones in line otherwise you will be wearing 1 pad faster than the other and having to get new pads more often

 

looking at your last pic it looks like the bracket sits nowhere near the inside of where the fork bracket is the original calipers fix on the inside of the forks. i dont have my gsxr anymore to measure the difference in caliper shape but personally i would not be running those calipers if they donot sit where the originals did you could run the risk of boiling the brake fluid from the brakes dragging and go to having no front brakes. as i said before you need to get the middle of the new cailpers sitting where the originals sat that may mean getting some spacers made

 

[HR][/HR]The SV uses the same rotors and brackets at the M90 and the same calipers. People have been converting SV brake systems using the same calipers and these brackets for years so I am not too worried about that part. The actual brackets bolt pattern to an exact fit to our forks but our lower fork design is why I had to modify it. Can you tell me where you are hearing about the offset being different and that may be the reason I had to add the washers. I checked the front wheel and the amount of drag is negligent after my slight adjustment as the wheel spins freely when it is off of the ground. I also checked with my Mechanic and he said the minimal amount of noise I am hearing is fine. I can't even hear it if i am going over 5 mph without a helmet. I am in the testing phase so no long trips, speeds over 35 mph and areas where there is no little traffic.

 

you only have to look at the pics of the conversions and you can see that the rotors are offset

 

I'm going to venture a guess that the sound you are hearing, especially since it has almost subsided, are the brake pads bedding-in to the rotors.

 

 

 

has your mechanic said that the rotors are a exact match because the sv riders site is showing that they are offset when they show the final result of the conversion they may have been doing it for years but how wide are their front hubs and the distance between the rotors is that the same as a m90 i would find a sv650 and even if you just measure the distance from rotor to rotor. but then the forks could be wider or narrower their is so many differences you could have.

are you just going by what ebay says about rotors they can say that the rotors will fit that model but when you get them they are not compatible.

going by the parts sites the sv 650 rotors are 59210-38G10 and the m90 has 59210-08F30 not even close to the the same part numbers so where are you getting the information that they use the same rotors?

 

That's why he added spacers to compensate for the offset the bracket is designed for...

 

the adapters are for a sv650 not a m90 even with the spacers he has in have a look at the picture they are not even level with the inside of the fork mounts still. i am trying to help him understand that you still need to line up things so you dont have problems latter on even bike builders mock up to get things right.
a least he his really trying to customize his bike to stand out from the rest

 

heres another brake upgrade to try
