2007 R1 Front and Rear end........

[axiom-r]

I am recently in possession of a complete front and rear end off of a 2007 R1!   The parts are fantastic and I am hoping to mount both ends on my 1993 FJ1200.

I have been reading a lot here about all the various wheel and suspension mods. I think I have plan for the front and I am optimistic the the entire front end will go on (I will need two inch fork extenders).  The rear end is looking like a bigger challenge so I have a few questions (yes I did search 1000 times).

1- what is the width of the stock FJ swing arm at the mount pivot?
2- what is the stock front end geometry; Rake Trail and Offset?
3- does anyone have knowledge of a 6" wide rear wheel successfully used on a late model FJ?

The parts are so nice- I got them for a song and as they sit on the garage floor next to the FJ I am super excited about bringing the FJ to the next level and not selling it!

Much appreciation to anyone that can shed light on any of the above three questions!

Cheers-  tim

I don't think the forks/wheel are setup for a speedo drive.I think they run a sensor off the tranny.The shock mount linkage on the swingarm is different than any of the FJ's.The six inch wheel will be a bit of work.

1- what is the width of the stock FJ swing arm at the mount pivot?

9.697" per Marc Rittners write up on the YZF1000 Thunder Ace swing arm conversion on Barry's site: http://www.fjmods.btinternet.co.uk/MarcRittner.htm

You may consider using the YZF750 needle thrust bearings Marc used in his conversion. I have them on my T-Ace swing arms. They are cool.

As mentioned, you need to think about your speedo.

Frank Kookaloo Moore converted his over to electric with a custom display, very cool indeed, but then again, his whole fucking bike is cool....

Pat,

I think your FJ is bretty badass also..... AND shiney!  

dash option....... dang if modifying aint a sickness  

[axiom-r]

Andy- thanks for that info! I was surprised that those specs were not more easily found on the web!

Pat- I had to go back and look at Marc's write up again- I missed the swingarm dimensions thanks for pointing it out. I doubt very much that the R1 swinger will work on the FJ as the pivot is over 10".  I am going to try though.  I have been looking with great interest at Frank's modded gauge.  I decided that I really need to keep my stock instruments because my 93 has only 13k original miles and is in very good condition. I want the suspension upgrades but a close to stock look at the bars etc. I will probably start looking for some first gen FZ1 wheels to use so that I can keep my speedo- that means these sweet 07 R1 wheels will be up for grabs.

I found this extender (here on the FJowner's board I think) that might work to allow the nearly 3" shorter 2007 R1 forks to mount. Shown just below the top triple- the extender slips over the fork top and then steps back down to 50mm adding 1-2 inches to the fork length.



Here are the parts I scored:


And here's the FJ I want to land them on:


I am hoping to keep the stock exhaust system as I have one of the SS Delkevic collector boxes.  Does the FZ1 Thunderace swingarm allow the stock exhaust or does it require an aftermarket system?

[Travis398]

looks like a nice setup, I haven't seen this. Do you have anymore info on it? It would be nice to know if it was custom made, or on an FJ.  

[Yamifj1200]

The 2002 FZ1 front end on my bike does not support a mechanical speedo drive. I think thats gen 1..... I went with a Garmin GPS for my speedo.

Travis- they are from a company called Cycle One Off...http://www.cycleoneoff.com/Photo_Album.html scroll down from the top to locate them.  

Picture shows them mounted on a V-Rod I think....  Don't tell anyone I am considering aftermarket HD parts for my FJ!!!

The downside on these is that they are not adjustable- you have to pick an extension size in advance (1" - 2" or a custom length) and then because of the shoulder design on the part they will only ride at that given extended height. I have seen some extender fork caps that thread into the fork tops and are at the same 50mm diameter so you can slide the front end up or down in the clamps to adjust the front ride height as needed- unfortunately (for me), these cap replacements are very expensive and only available for the 09+ R1 forks.

Yamifj12000: I stand corrected- I need to find 97-03 YZF1000R wheels.  As stated by another member here these are the only wheels that allow for the R1 Brakes and maintain a mechanical speedo drive....  I am hoping to do a direct swap with someone that has equally nice YZF1000r wheels!

Tim, for your front end, if you want modern cartridge forks (you do) *and* keep your speedo, a popular option is the YZF600 fork conversion. This is a conventional fork but with springs and Race Tech cartridges, a very good fork.
If you want the newer design upside down (usd) forks, and keep your speedo, 2 options are the 1994-98 YZF750 forks as done by Marc Rittner documented on Barry Edward's web site (posted above)


Or the 1992 FZR1000 USD conversion shown here:


In all cases, you gotta change your bars:


Cartridge forks are the way to go....

I am hoping to keep the stock exhaust system as I have one of the SS Delkevic collector boxes.  Does the FZ1 Thunderace swingarm allow the stock exhaust or does it require an aftermarket system?

You mean the 1997 YZF1000 Thunder Ace swing arm? Yes, you can keep your stock exhaust. Worst case is that on your '93 you may need to bend the black frame brackets out a smig to clear exhaust can mounting bolts with the swing arm.  You can even fit some nice light weight slip ons like I did here:


Notice in the picture below, to get clearance between the exhaust can mounting bolt and the swing arm, don't put the nut on the inside against the swingarm like the oem setup.  I used a low profile round head cap bolt and put the cap head on the inside, facing the swing arm, then installed a stainless steel acorn nut on the outside (with blue Locktight)  Voila! Clearance. I think it doesn't look too bad.

Pat, that bike is an inspiration!  I knew that I would be losing the stock bars since they will not fit onto the R1 USD forks.... so I am thinking about this set up I spotted on the FZ1 board. These Easton bars and clamps look sweet and will easily mount onto the R1 top triple with a quick drill and tap of the existing clip on locating bolt holes. The holes are a bit more widely spaced than the typical bar mounts would be but the long flat section of the Easton bars allow for this. If I can source an FZ1 top triple then I can use the rubber mounting as shown in the picture too. The FZ1 shown has 09 R1 forks installed in the stock FZ1 Triple Top.  It also has the custom made Fork Cap replacements that extend the forks 16+mm.


At this point I am thinking about using the following gear (partly because this stuff is already here in the garage and partly because these are the components proven to work by those that have come before me).

Front End:
2007 R1 USD forks- modded with extenders to bring them up to FJ length.
2007 R1 6 piston calipers on 320mm floating discs
94-98 YZF750 or 1000 Front Wheel (I believe these are the same)
(I do not know if the YZF wheel's three spokes are thin enough to fit between the 6 piston caliper's gap when mounted to the 07 R1 fork. I also don't know if the YZF brake rotors are offset properly to match the R1 caliper position- hoping this is a standard offset that stayed the same).



Rear End:
1997 Thunderace Swingarm
(Pat you caught a typo on my part I had stated FZ1 Thunderace Swingarm but it is the 97 YZF I am shooting for. I am seeing inconsistent info on the production of the Thunderace- was it only offered in the US until 97 but continued production overseas through 2003?)
94-98 YZF750 or 1000 rear wheel. (I believe these are the same and hopefully no fitment issues with the Thunderace swingarm).  I do want to run a 180 rear tire so I am assuming that I will have to recess the sprocket, shave the cush-drive or both to achieve chain clearence
2007 R1 Rear Caliper and carrier. (Hoping these mate with the YZF rear wheel without too hassle).
Penske Rear Shock with the adjustable type of dog-bones so that I can dial in the ride height as needed. - planning to shave the shock well on the swingarm and remove some of the light gusseting as suggested for clearance.

I am going to mess with this massive R1 swingarm first and see if there is any chance it will fit. After spending some more time with it this afternoon I think the pivot can be shaved down to fit the FJ just like the Thunderace process described by Marc Ritter- I am much less sure about the massive under bracing clearing the stock exhaust- I am gonna check it out though!  My other concern with this arm is that is it about 2inches longer from pivot to axle so it will add to the overall wheelbase.



Stock exhaust set up polished stock downtubes (are these really SS?) with the Delkevic SS collector box and stock black chrome mufflers...

I've know for awhile that I wanted to upgrade the FJ suspension and wheels but finding this R1 stuff put me into motion. Not sure how long its going to take me but the FJ will probably come apart over the holiday....  Should be a good time!

Andy- thanks for that info! I was surprised that those specs were not more easily found on the web!

Sorry, it was easily found on the web.  Actually it was on this site already.

As was the offset, but I was in a hurry yesterday.  35mm.

You'll find a tiny bit of information here but he's using the earlier forks.  Don't know if the YZF1000R wheel would still work and let you retain the speedo drive or not.

[Harvy]

  My other concern with this arm is that is it about 2inches longer from pivot to axle so it will add to the overall wheelbase.

The FZ1 swingarm is also longer by about the same amount...... not a problem with the rear end raised using adjustable dogbones.

 There are a few yzf750r arms on ebay as well as at least one thunderace arm.There are a few yzf750 and 1000 rear wheels too.You will need to come up with a pin on the fork to stop the speedo drive from spinning.The calipers look just like my yzf 750 calipers.Worst case you will need to make an adapter plate for them.I have now idea if the fj steering stem will easilly fit into the r1 triple clamps.

axiom-r,

Realize that if you're using tubular bars that mount to clamps on the top triple, then your fork does not need to be the same length as the FJ fork.  You won't have to have the length that sticks above the top triple and gets the clip-on bar mounted to it.  That's probably 30mm or so.
