Ducati Monster Forum

i picked up a set of 2006-2007 r6 forks with matris F05R's :-). i believe i bought them for a fair price. considering what i was going to buy djrashinal's for.

http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=200456316101&ssPageName=STRK:MEWNX:IT#ht_1819wt_886 (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=200456316101&ssPageName=STRK:MEWNX:IT#ht_1819wt_886)

i cannot wait til they arrive. from my findings the regular 06-07 r6 has 50mm upper and 52mm lowers. the 06-07 r6 "S" i a totally different fork(non inverted).



this is the part list i used with a early 17/20/25mm axle

* 06-07 r6 forks (50mm top, 52mm bottom)
bore the left axle(22mm) side to 25mm and have a 1.5mm think sleeve made for the right (28mm) to adapt the 25mm axle.

* 17/20/25mm monster axle w/sleeve nut . shave the lip off the sleeve nut

*metal sleeve spacer from the speedo drive. will have to destroy it or have one made.

* 06ish radial calipers. for clearance issues, shave 2mm off the inside of the calipers. i also filed the lettering off the front spokes. most jap bikes use the same mounting, but don't even think about the 6 pot r1. some calipers are slimmer so you wouldn't have to shave them.

* (4) m10x1.25x75+mm bolts. i would say 75-85mm would be good. extra insurance

* ( 8 )5/16 washer from home depot .11 each. to space calipers out. 2 on each brake mount

* 20 gauge sheet aluminum. to shim the bottom triple for the 52mm forks

* r6 fender. pay close attention. 06-07 fork only have 2 mounting holes. 1 in front of the leg and the other behind.


rotors didn't have to be spaced. no special axle spacers had to be made. the speedo drive spacer works w/o moding


25mm monster/ss axle swap parts

*25mm monster/SS axle and nut
*25mm speedo delete spacer part# 71410281a $7
*bore forks out to accept the 25mm axle
*machine 5.82mm off the length of speedo delete spacer

please check your work measurements before machining. machining of the calipers are still needed and spacing the caliper out 5mm to fit 320mm rotors.

that looks awesome! i was thinking about picking up someting like this too, no need to go to SBK forks, but still get the 25mm catridge.

theres a ZX-6 fork out there with the same F05 internals.... what brakes are you going to use?

i going to use the r6 calipers. i could use either the gsxr or r6(same bolt spacing), but the r6's are nice looking and smaller and suppose to be monblocks. r6 calipers are an upgrade over the gsxr's.

i'm unsure what masters i'm going to go with though.

i guess i'm more or less going to gther parts cause i have to buy clip ons, calipers, masters, spacers, shims, etc.

another plus if it's true. the seller said the forks are sprung for a 165ib rider. after looking on racetech's site, a 165lb rider on an r6 uses a .853 spring. and the spring rate for my monster needs a .85 . i really hope that's right. if not oh well. 

let me know how it works out. if i had saw that i would of bought it under you.  ;)

i really dig those F05R catridges, ive seen them go for about $700 bucks...but if i can get a hold of them inside an R6 fork for that price. man, id be ontop of it. Check the caliper spacing...maybe you can get Brembo radials to fit....

Im looking all around for these gem sales...really like those R6 forks too.

woooo! brembo and radials don't go well together. don't quote me on this, but i believe the bolt spacing is 108mm.

i'm a link whore.

whys that? they fight over which credit card to use? [evil]

too bad the 6-pot r1 caliper won't fit.   :(

ha, thats over kill.

I cant find F05R catrdiges anywhere. :(

sell me those forks.  [evil]

HEY! there's nothing wrong with over kill.

wera classifieds get less action than a priest.

i already bought the 848 forks anyway.  would of prefered the R6 forks though. post pics up when u get the conversion done.

i'm not sure if i should keep the progress in this thread or start another? but i'll post pics and such throughout the build.

this guy has 20mm ohlins installed for $250

my forks are in transit. whooop whooop! they'll arrive on the 21st.

thanks for the link im goign to start doing some research on kawi forks and 20mm catridges. ohlins now discontinued the 25mm and are making 30mm only... maybe i can find some 25mm forks.

i've found some sources for the radial caliper spacers.

i just don't i could swallow $1k on calipers. the r6 ones are <$100 all day, and they're suppose to be really good or at least for a street bike. those are pretty gnarly though.

i got my r6 forks w/matris internals today. fist pumps all around. i went to my buddies shop, cause he has a digital caliper, to take measurements off the forks. all the measurements are in mm's.

So, what are your plans for the axel...or bearings?

i probably going to buy a r6 and machine it to fit, and buy different bearing. or have a custom axle made. not sure yet.

save your self the trouble, ill buy those forks off you.

trust me, you wont regret it.  ;D

on a serious note though. look like all you need an proper axle and some spacers.

Which wheel?

right now i still have the oe 20mm axle 3 spoke brembos.

HE, i was waiting for you to post. no trouble for me  ;D

ok, I was thinking you were working with a 25mm bearing wheel.

Those fork axle hole seem to be such odd numbers?  What size is the axel suppose to be on the R6?

For example later ducati axels are an even 25mm on the small end and 30mm on the big end.

i have no idea on the r6 axle, but looking at pics on ebay. the only has 2 diameters. 1 for the (right) 28mm side and the rest of the axle is about 22mm's.

i believe this is how i can get this to work 1 of 2 ways.

1st:
r6 axle
22mm i.d. wheel bearings and new hub spacer
required axle spacers

2nd:
custom axle
25mm wheel bearings and hub spacer
required axle spacers

that's good to know about the 25mm axle. i didn't know it had those diameters. i've never seen one. is there a lot of thickness to machine it down 2mm on the big end and 3mm on the opposite end?
open to any thoughts

i found 22mm bearings. 22x47x14 honda bearing. honda part number 91002-MCT-003 . about $15 each.

how big are the bearings on your bike? id keep it simple and use your own axle with 2 spacers for the axles and 1 for the wheel spacing.

i have the 20mm axle. 20x47x14

since HE told me to keep it simple. so today i pulled my old forks out, and i believe came up with a better axle plan.

this is how my 20mm axle is the forks. sleeve nut on the left and the axle extracts from the right.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04046.jpg)

here's my plan. flip the axle so the axle extracts from the left and sleeve nut on the right. then machine the 25mm side down to 22mm (left side r6 fork), and have a new sleeve nut made for the 28mm o.d. side (right side r6 fork). the cards are showing what the axle diameters would be after machining.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04047.jpg)

then i could keep the 20mm bearings i have since there's nothing wrong with them.

there you go. 2 spacers. all you need is one more to align the wheel and your good.

YAY HE MAN HUGS!

Teaser
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04048.jpg)

i hate chew. looks awesome though!!!

i'm probably going to have the axle machined tomorrow.

but have 1 question.
should i have a new sleeve nut machined to have a o.d. of 28mm or should i have an aluminum sleeve to fit over the original thread sleeve to make it fit?

the second choice seems kinda sketchy and a shortcut to me

i dropped off my stuff to the machinist today.

i'll post pics and measurements of the solution he came up with. i'll have pics and such up probably late monday. hopefully before my surgery on tuesday. yay. 

i would grind off those threads and put a new spacer ontop.

the threads dont give you a nice surface to apply pressure, and if ou get something to thread over it, you will only get your slef into shit when unthread the nut. youll just end up backing out the spacer  and it will be tough since it will be rubbing on the fork leg's axle hole.

when i took him the stuff i told him what i had in mind and open to and thoughts, since he's the machinist. the idea he came up with was really smooth. bore the 22mm leg to 25mm for the OE ducati sleeve nut to fit and machine a 3mm sleeve spacer to add on the axle to fit the 28mm leg. then on the 3mm sleeve spacer, he's going to tig the outside edge of if to prevent from moving or losing it.

I had a bb7 started out with a monster T, switched to a boxxer, and my last fork on it was the 888. The 888 was by far the best fork the boxxer just seemed to have too much flex in it when I rode the rougher courses. I wish I still had that bike with the 888.

i haven't forgot about the thread.i had shoulder surgery last tuesday, and is a minimum.

i'm really wanting to land a set of these. so this project might take a little longer than expected.
(http://i181.photobucket.com/albums/x251/seusssandm/art_magura_190ebz.jpg)

hope your shoulder gets better.

you can pick up a used 1098 radial master brembo for about $120-150. if thats in your budget. im sure the magura one or the Brembo RCS one are RETARDED expensive!

they are pricey. i thought about the 1098s. is there a way i find out the piston bores?

i picked my forks and axle from the machinist a couple days ago. i finally got everything bolted up and fork legs shimmed.

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04064.jpg)

the fork 22mm fork leg bored to 25mm and a sleeve added to bring the other side to 28mm, clamps perfect.

a problem has seemed to come up with the axle, causing wheel fitment issues. on the inside of the forks, there are shoulders that are throwing off the wheel.

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04067.jpg)

i'm going to pull the wheel back off and look at everything again. this is what the axle is doing. since the fork has the shoulders, its putting the sleeve nut more towards the center. as you can see in the pic, the axle is tightened down all the way and has about 1/2in hanging out on the left.

one thing i thought would be quick and easy was to machine the shoulder on the sleeve nut off. then after thinking about that, i was worried i would always have trouble centering the wheel. 

i received my radial calipers today.
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04081.jpg)
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04082.jpg)

4 piston radial monoblocks w/ good pads and lines. i going to get custom SS lines when finished, but for $62, i'm not complaining.

on the wheel spacing, the wheel has to come over about 10mm's. so i'm going to get the shoulder on the sleeve nut machined down.

today my other stuff came in. 999 masters and SS swingarm. that's going to be in another thread. ;D

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04095.jpg)

just a few more things and the front end will be complete.

i got everything semi installed. fitment has very tight spacing. between the caliper and the spokes of the rim, there's only about a 1-2mm clearance. it seems a little close for comfort for me.

what do you guys think?
(http://i181.photobucket.com/albums/x251/seusssandm/DSC04096.jpg)

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04097.jpg)

way too clsoe for comfort IMO. can you grind off some of the calipers and refinish with some caliper paint??

way to close. im pretty sure as you ride everything wll flex and something is going to give.


im not sure how much grinding you can do without compromising it since i dont know the thickness of them... maybe you should look into other calipers with similar spacing.

would it not be easier and safer to buy a R6 rim? probably a whole lot lighter as well.
Don

Don that's what i've been thinking, but they have different rotor size and mounting cause the rim is my problem. everything would be good if the spokes weren't so fat. i saw on a monster before that somebody used cbr 600 rims, front and back. they look very nice, they look similar to the OZ rims.

the caliper wall thickness is about 4.3mm thick, not exact measurement, so not a lot of room to work with there. i'm not sure how much spacing i would need to be safe.

But all the work you did for the spacers would of been for nothing. lol

i guess future lesson is to buy everything and then start machining parts

not all of it was a waste. i can try to use a ducati 25mm axle,and not have wasted any money on machining. on the side where he adapted the axle to 28mm, he shrank the sleeve spacer on the axle not welded.

Why wouldn`t R6 wheel, axle & discs work?

well i was trying to keep the 320mm rotors, but seems kinda dumb now for and extra 10mm's. i think the r6 stock fork width is wider than a monster, i'm worried about the spacing of everything. something else that i'm in the dark about unless to buy it.

this is what i'm working with. causing a very big headache.

the spacing between the calipers is exactly 35mm. the center line width of the calipers is 119mm. after doing some searching i THICK the r6 rotors have a 0mm offset, so thery're flat, but i still don't know the width of the rotor spacing on the wheel.

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04099.jpg)

Yes, they are.
Don`t remember offset but almost flat.

hey greenmonster, so you have the front wheel and rotors too? if so, when you have a free minute, could you measure the rotor to rotor width for me.

Just a thought - is the distance between fork legs the same on an R6 as on a monster?

'cos if the R6 triple is wider, then the R6 wheel may still not fit.

the spokes on the r6 wheels seem to be narrower than ducati 3 spoke wheels.

Haven`t been to my shed yet so no measuring.

In 1 of the 2 variations of discs/caliper setup I had 4mm
clearence caliper-spoke, no issues.

In my pic below I had R1 320 mm discs, now I have another setup
w 300 mm EBC on caliper adapters.

what i'm trying to figure out is the width of the rotor mounting on the hub from left to right. if i were to use the r6 wheel and rotors that have 0mm of offset, and the rotor/hub width is wider than 119mm, than it would be hard to work with.

ohhhhh my. i spent about 4 hours today on Galfer's rotor tech sheet. i exhausted. now i still have to get wheel measurements.

R6 front wheel:
Fr outside disc to outside disc: 128 mm.
Disc thickness: 5 mm.

W my Showa forks, wheel centered as original Duc wheel whithin +- 1mm,
: Center of hub to fork (fr riders POV): Right 5mm, L 10mm.
This is what you could custom fit f alignment, calipers etc.

Hope this helps in someway.

Besides the eventual yokes differences,
you also have to consider front-rear wheel alignment. ;)
It`s not an easy task...

thanks green.

what rotors are you using with the 128mm measurement

EBC wave 5 mm (R1 ones had the same measurements).

ooooh man. well an r6 wheel and rotors are going to be 8-9mm too wide.   

Would it be possable to fit a complete R6 front end? triples, forks, wheels and brakes or is the stem a different size?
Don

"brownwhale" has done this swap. he first tried the r6 triples, and found that they had a negative effect on the steering. after he crashed his bike, he hasn't been on since last year.

i almost think if i can shave a mm or 2 off the calipers that i would be safe. ß

BRAKE SITUATION RESOLVED

shaved 2 mil off the inside of the caliper. keeping OE 3 spoke brembos.

the machinist i've been working with kinda let me down. all he could do was come up with "what if " scenarios and wouldn't touch the calipers, so i found another guy.

seeing a CNC machine in action for the first time, it's breath takingly awesome. i know that not a real world.

Did you take the calipers apart to see how thick the wall that you machined is?

yeah i did. it was originally 6.01mm

Dont blame him. I mean, from an engineering perspective, the brakes need to be thick to dissipate heat and be ridgid enough to not break. So he probably has a fear of the brake calipers breaking open from al lthe heat and pressure, then you running right into a wall. And then hell have a guilty conscious. Ofcourse, from a machinist point of view, you got hire to shave 2mills off. why you want it done, is not his problem, i just know how to use the damn machine. lol

i told him i understand that he didn't want to do it. i was almost on the path of buying monoblock brembos. i called and talked to fred at yoyo and explained what i was doing, he said that's not going to hurt anything. he might be an engineer or anything, but somebody else with my same understanding.

when i ride i don't have frequent stops, not going over 70mph, and probably will never see a track. i don't think the pistons will blow out or anything, but i always do a pre-ride look over before riding anyway.

random info, but when i went to physical therapy yesterday, i was able to find out my clamp force of my hand. a mire 110lbs.

is that a lot? and was it the left or rigth? lol i figure hte left would be stronger simply cause of the clutch!

no not a lot. that was my right(brake)hand. it wasn't an attempt of bragging rights. i was getting around to saying, my pu$$y grip hand couldn't apply enough force to blow the caliper pistons through now 4mm aluminum. i understand more force is applied from the leverage of the lever, but still.

i think i'm good

it's average-low...... he should be around 120ish...he'll be back up to it soon  [thumbsup] Start rock climbing and he'll be pulling 180-200 in no time!

i don't know it came possible. the planets must have been inline or something. after to bolted up the calipers with the required spacers, the rotor is almost dead on the money. the rotors are only off center in the calipers by maybe 1mm.

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04132-1.jpg)

HOOO make the beast with two backs!n RAY!

the only thing left is to buy brake lines and 2 more caliper bolt and 4 washers. i just have one bolt in each caliper now.

i'm probably going to do the single brake line with a bridge, rather than 2 from the master. cleaner :)

updated the first post with my parts list.

here's the the most up to date pic i have of her. i've been neglecting to buy a fender since i finished the swap. i'm going to have to buy a r6 fender since there's not enough mounting holes on the forks to accept the monster one. the brake and wheel clearance issues i was having hasn't caused any problems. i put probably 1000 miles on it. when i swap to the OZ's, it'll give me a little bit more room. being the bonehead i am, i going to swap the 20mm front to 25mm.

(http://i181.photobucket.com/albums/x251/seusssandm/DSC04423.jpg)

looks like it would take the 999 fender

here's the right fork leg. thanks for the suggestion about the 999 fender. i was trying to find a very minimal fender. (http://i181.photobucket.com/albums/x251/seusssandm/DSC04644.jpg)

The carbon fender from the S4Rs looks like it'll fit. It bolts onto the ohlins folk the same as the 999. I have one if your interested.  [cheeky]
