eddiegsx Posted April 17, 2020 Posted April 17, 2020 I'm sure this has been asked before so please forgive me as I don't seem to be able to find any info on here. I want to fit a gsxr/bandit swingarm to my efe, any info much appreciated. Also, does anyone do drag slots for the above? Cheers. Quote
Not_so_Evil_Lloyd Posted April 17, 2020 Posted April 17, 2020 Bandit arm is easier. Which ever swinging arm you decide on you will need to make new upper and lower mounts for the shock and linkage. When i got my efe these had been done but not to a good standard so i used the dimensions and made newer better braced ones. The bike had a GSXR arm in it which was a shit fit. Its slightly narrower than the original arm but not so much more narrow that you would easily get a spacer in. Also the pivot on a gsxr is a solid spindle at 17mm. The Efe is 16mm so yes it'll go through but it'll be sloppy. Mine had a bunch of play because of this. Also GSXR arms do not have a mount for torque arm for rear caliper. Mine had been bodged onto the frame kinda like the GSXR should of been but way too shit I binned that arm in favour of a bandit set up. Bandit arm has a mount for the torque for the brake so that kept it simple. Bandit pivot spindles if i remember right are 25mm with hollow spindle. And the pivot point is narrower. So i made up some top hat spacers that sat inside the bandit pivot bearings sleaving it down to 16mm and also take up the width to the frame. I can't remember the dimensions of them unfortunately but i'm sure someone on here will. Or you'll just have to wait till i get round to my 1100ET project with bandit arm as i think they are the same width at pivot as EFE even though they are twinshock bikes. 1 Quote
eddiegsx Posted April 17, 2020 Author Posted April 17, 2020 Thanks for that info, great help. Where I'm also concerned about is the angle of the arm and which shock is best for the job as I don't want the questionable handling to be any worse. The alternative would be to leave the existing arm and fit a 5.5inch gsxr wheel in that, I have a wheel is this a straightforward fit? Quote
Not_so_Evil_Lloyd Posted April 17, 2020 Posted April 17, 2020 Everything from the 80's has questionable behaviour (and i include myself in that statement) If your efe is totally stock atm and you are looking for simple budget friendly upgrades then a GSX600f front wheel will go in standard efe forks with new spacers as its a narrower wheel at the hub. And if you space the discs out (get a machine shop to make one complete spacer up and use longer disk bolts) you can use GSXR slingshot front calipers, they'll bolt straight up to the efe forks. That's what i had on mine at 1st. Then i went to GSXR slingshot yokes with gsxr 1100 forks and wheel re using the slingshot calipers i already had on the bike. The head bearings and stem are a perfect fit just make new steering stops. That was a RWU front end. USD look cool but cost more and you lose a bit of steering lock. Used 1100 fork legs as they are longer. Rear end i'm sure a gsxr slingshot 4.5 rear wheel is fairly straight forward into stock arm. Which would give you a 160 rear tyre. I was always under the impression that 5.5 wheels were too wide for stock arms but i seem to remember someone on here making it work. I just can't for the life of me remember who it was... 2 Quote
ZenViking Posted April 17, 2020 Posted April 17, 2020 I am fitting a Bandit rear wheel in my stock EFE swinger and looks like it will fit with new spacers and machining of the sprocket carrier. it's 4,5" and that will get me 160 rear tyre. For Front i did a direct swap with a GSXR1100 W 2 Quote
eddiegsx Posted April 17, 2020 Author Posted April 17, 2020 (edited) I have a gsxr1100m front end and a bandit 600 back wheel, would that setup work with the standard arm or would the front tyre be too wide and upset the geometry? Cheers. Edited April 17, 2020 by eddiegsx More info Quote

Cheers. Is it a complete front end? Not sure about your front fork and wheel or the eventual Geometry, but have a look at this excel with the headbearing size for changeability: https://oldskoolsuzuki.info/archives/744. Your bandit wheel should fit, I'm in the prosess of fitting a 600 Bandit to my own bike. Just waiting for some spacers, but you will need to machine down the sprocket carrier so the rear sprocket doesn't hit the inside of the swinger and an offset front sprocket. 1 Quote

Issue is not the wheel, but a 180 tyre which just fits, or just doesn't fit, depending on the tyre brand. 2 Quote
Not_so_Evil_Lloyd Posted April 17, 2020 Posted April 17, 2020 I used a 170 tyre on my 5.5rim but that was in a bandit arm. Glad i haven't gone mad i was sure there were some bikes on here with 5.5 in stock arm. 1 Quote

eddiegsx Posted April 17, 2020 Author Posted April 17, 2020 Thanks again guys, very helpful and gives me plenty of options to think about. I have quite a few parts hanging around including a complete efe in bits that have been collecting dust for a while. Now got a bit more time on my hands with this lockdown thing, so just tidying up my fairly standard efe ready for the big escape and making plans for the above. Im a slow mover but will do a project thread when i get organised. 1 Quote
mark35gun Posted April 21, 2020 Posted April 21, 2020 5.5 rim definitely goes in a stock efe arm i have one in mine with 170 tyre there s clearance but not much 1 Quote
shaunbrogdon Posted June 17, 2020 Posted June 17, 2020 I went with GSXR11 arm as I had one sitting. Be easier to use B12 arm as it's one less bracket (torque arm mounts to frame on GSXR rather than onto arm on 12). There are a load of photos of the brackets I made and TIGd in in my build thread.

TrunKz Posted November 21, 2021 Posted November 21, 2021 Efe with GSXR 1100 swingarm where can I fix the torque arm on my efe frame? Quote
Joseph Posted November 21, 2021 Posted November 21, 2021 On my Katana and GSX-E i ditched the center stand and used that point to fit the torque arm. Seems like the usual move when upgrading this kind of points on these bikes Quote
Joseph Posted November 21, 2021 Posted November 21, 2021 The tabs got cut off by a previous owner ? Welder time then Quote
yantosh Posted November 21, 2021 Posted November 21, 2021 Havoc's Mongrel is an EFE frame with a K5 gsxr1000 arm Quote

TonyGee Posted November 21, 2021 Posted November 21, 2021 is it a solid one, looks like it to me !!! if it is then you need to bolt the torque arm to the swingarm not the frame. Quote
Joseph Posted November 21, 2021 Posted November 21, 2021 Whats the difference ? Do you have side to side pictures ? 1 Quote
