Whew, guys. Sifting through tidbits of info here and there on how to get a wider rim on the fz750 has been a bit exhausting. I was attempting to do my research before I started asking too many questions but I'm just a bit overwhelmed at the moment. Please keep in mind I am in the "good ole" USA. Also, I would be doing this mostly for aesthetics as the 130mm wide tire is just puny looking. So, here is what I am looking for.... The EASIEST way to get a wider tire on the FZ. By easy, I mean the least modification and a high availability of parts necessary to get the job done. I read in some other posts that a FJ1100 swingarm will bolt in to the FZ. It looks to me the FJ1100 was only available in 1984 and 1985. So here is what I am thinking. FJ1100 swingarm and the stock rear 16x3.5 rim that would be found on the same bike.. which will take a 150/80 tire. Sure, my selection of tires may not be as good as a 17" rim, but again.. I want this to be easy and I won't be racing the bike.. just riding it on the street. I do wonder, however, how a 16" rear will look on an FZ and how it will effect gearing... feel free to comment on this also. Also, maybe a 20mm wider tire wouldn't make much of a difference, though I think any extra width would help in the looks department. So what, exactly, is needed off the FJ1100 if this will work? Do I also need the linkage/shock/spring from a FJ1100? Do I need the rear caliper/rotor(which appears to be much larger than the FZ)? What about the (excuse me but I can't remember the name of it) piece that connects to the rear sprocket and sits in the wheel. Now, assuming that I can get all the parts needed off a FJ1100 (which seem to be very easy to find here in the USA), will I have any issues with the chain alignment? If so, what are my options? I've tried to be clear but I'm not terrible mechanically inclined. I rebuilt a 1986 Yamaha Radian a couple years ago.. I can work on carbs. Have never gotten into engine internals. I worry about the drivetrain of the motorcycle though since failure could mean death. I want to do this the "right" way if there is a way to do that. Maybe there is an easier way??? Thanks! Kirk

Hello There is a few different ways to do the wider rear rim thing, some install the complete rear end of an exup, that will give you a 5.5 x 17 rear wheel(good tire selection). I went a different route I fitted a fazer 600 swing arm and rear wheel 5 x 17 this i feel is a good mod. they both need some engineering to get right. how much work a you willing to do ? You can P.M me if you need more info. hope this helps.

You can P.M me if you need more info. hope this helps. That's a nice looking bike you got there. A quick google search tells me that an "EXUP" is a 1989-95 FZR1000. Will any of those years work? Ebay appears to be void of one single fzr1000 swingarm for that year range. Just one from 88, which I believe Kevin (on this forum) fit on his bike.. but also not without a bit of work. I may be interested in the Fazer 600 method as well. What years can you pull the swingarm from? Did you have to swap out the linkage/shock/spring/brakes as well? I don't mind doing some work.. hell.. I'm going ot have to put in quite a bit already just to get this bike looking half way decent . I'm not a machinist, though, so I have to understand the process enough to be able to explain to a machinist whatwork needs to be done. As I stated before, I just want to make sure it is done safe.. and 'right'. It seems like there are a lot of options. We definetly need a sticky or FAQ where we can define the options to clear up confusion. Thanks!

Hi Again What year is your fz?, if its an early one 85/86 the rear linkage, shock are different to the later ones which are easier to convert, i will post some pics, my bike is a 86 so i had to cut off the center stand mounts have some spacers machined to center the fzr1000 linkage i used in the lower mount. the fzs600 98/99 fazer swing arm is narrower and has 5mm spacers each side again to center the swing arm in the frame

The 88 FZR1000 arm is the easiest way to get more width. It will go straight in and uses the same shock linkages as a 2MG FZ - you just need to adjust spacers and worry about the chain run depending on which wheel & tyre you use. I think the EXUP arm uses a different linkage, so probably alters the effective spring rate, and needs to be machined to fit the FZ frame before you get into the spacer/chain run question. As someone else pointed out you can get a 180 tyre into the stock swingarm - chain run is the biggest issue. picasaweb.google.com/FZ750Horse/BuildingTheBeast#5163232721002936370

yamglenn: I have an 86 FZ as well. I did see kevin's post where he had to cut the center stand mounts off. I dont' have a problem with doing such work. Some pics would be awesome if it's not too much trouble.
fz750horse: I need to check my frame to see what my code is.. not sure what I have yet.
I've PM'd scobri as he states that a FJ1100 swingarm bolts right in.. and he's used a yzf600 5" rear wheel and now a FZR1000 EXUP rear wheel in the swingarm.
I've PM'd him for more info as this seems pretty easy (as far as parts availability) to me. Asked him about the year of the YZF wheel and what modifications may have had to be made.. and if chain run was adversely effected. From the searching I've done I believe he has an 85 and 86 FZ.
Thanks for the replies guys! Kirk

Interesting Thread!! I have a 3ks Model and am also looking for the easiest swingarm to fit to allow wider and better 17" tyre choice Would i be right in thinking the fzr 1000 87/88 genesis bolts straight in and then just a case of sizing up the exup rear wheel??? Currently have fzr 400 rrsp 3tj yokes running r6 forks (43mm) so just need to sort the rear

I have used an 87-88 FZR1000 Genesis arm AND wheel which all bolted straight in with no issues regards chain run/tyre clearance using all the 1000 wheel spacers, wheel, shock linkages, sprocket carrier etc. ;D My bike is a 2MG model.

I did this way too on a very early frame just welded a top mount in. Then I changed the back wheel to a YZF750 for ease really because I have one of those too and can now swap wheels around. Just machined out the axle slots and adjusters and hey presto. Pictures on MGP thread

I have a TRX850 rear arm & wheel which I would like to fit to the other FZ if I ever get round to it. Seen TRX arm on another FZ somewhere which I thought looked good.

OK, I missed this before. How does one go about getting a wider tire into the stock swingarm? I'm assuming you mean there is a way to just change the wheel? Details would be much appreciated. I'd be happy just getting a 160 on there. Thanks, Kirk

hiya i have exup bits on my 2mg wasnt to bad chain aligment was the niggly problem but recessed the the sprocket and a spacer sorted that, here is my photo bucket it has some pics two albums s675.photobucket.com/albums/vv120/alliekat63/
