OldKat Posted May 16, 2016 Posted May 16, 2016 Hi, I'm new to the forum and collecting an old GSX750E this coming weekend. Have any of you guys fitted GSXR K1 USD 's and K1 swing arm to a 750E? I was offered a full set of running gear at a give away price and couldn't bring myself to say no. Thanks All. Dave Quote
Sheep Posted May 17, 2016 Posted May 17, 2016 Pop into the 'Vault' section and on page 3 you will see a chart on various fork/frame swaps...hope this helps 1 Quote
Swiss Toni Posted May 17, 2016 Posted May 17, 2016 Welcome to the forum 'Kat'! You have a good start there, most of which will fit the old chassis, the rest can be made to. Easily! Start a build thread, as we all love pictures! Plenty advice when you need it. Don't be affeared to ask! 1 Quote
OldKat Posted May 17, 2016 Author Posted May 17, 2016 Hi Gents, thanks for the pointers. Greatly appreciated. Will definitely start a build thread as soon as I get things moving. Dave Quote
KATANAMANGLER Posted May 18, 2016 Posted May 18, 2016 Welcome. Your main considerations for front end swaps are length ( will it give you the ground clearance ) and the stem length (will it be long enough to clear the headstock) . Stems can usually be pressed out and swapped. Fork length can be overcome using a stepped yoke. With swing arms the critical dimension is the pivot width. You can shim it and in some cases machine it down if necessary. Other considerations are spindle dimensions and mono-shock linkage and pivot positions. If you change the shock geometry you will change the suspension characteristics. The bigger concern with a 180 back tyre and 5.5" rim or a 190 and 6" rim is chain run and alignment. Clearing the frame and tyre side wall can be a ball ache. A 4.5 " rim 160 tyre will go into the standard swingarm with a minimum fuss. Some pointers to aid research but as a general rule of thumb anything can be made to fit it's just a case of how hard you want to work to make it fit. 1 Quote
KATANAMANGLER Posted May 18, 2016 Posted May 18, 2016 In fact, @Rene EFE just recently upgraded the running gear on his. The thread is here 1 Quote
OldKat Posted May 20, 2016 Author Posted May 20, 2016 Hi Rene. Looking good! What swing arm did you use? Quote
Rene EFE Posted May 20, 2016 Posted May 20, 2016 Swingarm is stock, modified to take a 20mm axle. Raised the rear by lengthening the linkage. It's gor a 4,5" GSXR wheel now, but I'm not doing it again because it was an absolute pain. Homemade caliperhanger en modded torquearm for the brake, std caliper. It works but when time comes, I'll just put a Slingy arm in. Quote
OldKat Posted September 25, 2016 Author Posted September 25, 2016 K1 Swingarm and USDs in place (I've got the deep braced and standard K1 swing arms, difficulty is choosing witch one to go with). Rear shock mounting now welded in place, H2M Engineeing in Hinkley made the top hat swing arm bushes to reduce to the ES swing arm bolt, 3mm taken of the frame mounts either side - next challenge - chain alignment and proper engine mounts. 3 Quote
Sigazpez Posted August 12, 2019 Posted August 12, 2019 Hi, Rene, i have exactly the same bike as yourself. You say you raised the rear by lengthening the link. Is that the upside down 'T' shape link,? And by how much did you lengthen it by,?, Any help would be greatly appreciated. cheers, Simon.

kingofvenus Posted August 13, 2019 Posted August 13, 2019 Mine has a 94 1100 arm on it. Is longer than stocker, back edge of tire even with taillight. Had remove a simdge on inside of frame at pivot, 520 chain helps with frame clearance. Has 750 teapot engine also... Quote
Suzukian Posted February 24, 2023 Posted February 24, 2023 (edited) On 5/19/2016 at 9:01 AM, Rene EFE said: Hello The front end of your GSX750 is exactly what I want to do to mine. Is there someway I could find out what parts you used? Is their a "modification" thread. This one just shows the pictures. Would it be too much to get a parts list for moving forward from you? I would be so appreciative for this help and info. Thanks Edited February 24, 2023 by Suzukian Quote
Suzukian Posted February 24, 2023 Posted February 24, 2023 After two hours, I found the data about your GS750 buried in another thread. Thanks, very useful stuff, and these parts aren't expensive in the U.S. Quote
BWhasty Posted April 26, 2023 Posted April 26, 2023 Please share the info on this fork conversion! Looking for something like this for my GS700E. Quote
