Chuwachi 0 Posted May 28 Share Posted May 28 Hey folks, I'm building something to look like a HRC RVF from the early 90's. Bought some 954 forks and yokes a long while back, but at a guess after fitting they are about 75mm too short. What's a good fit without too much grief, 954 yokes with other legs? Thanks in advance.

Member Contributer vfrcapn 303 Posted May 28 Member Contributer Share Posted May 28 The RC51, RVT1000, forks and wheel should bolt right in to the 954 clamps and give enough length. As I recall the spacing is the same with on the clamps between the two. Quote Link to post Share on other sites
Chuwachi 0 Posted May 29 Author Share Posted May 29 Oh ok thank you... But the 954 yokes are for USD forks which is what I want. I heard mention that some version of GSXR forks were an option. Quote Link to post Share on other sites
Member Contributer JZH 687 Posted May 31 Member Contributer Share Posted May 31 Quite possibly, but the most direct bolt-on is to use RC51 forks/wheel/brakes and the yokes you have. It's an expensive way to go, but it all works together and looks right. Ciao, JZH Quote Link to post Share on other sites

RustyA 35 Posted June 2 Share Posted June 2 RC51, SP1 bottom yoke. 954 top yoke. Bottom bearing RC51, SP1. With a 3mm spacer between the frame and bearing race. Top bearing, VFR Forks, RC 51 SP1, SP2. I used the Ohlins from my SP2. Front fender. SP2 Front rim. The SP2 is a 5 spoke. Matches the number of spokes on the rear. The SP1 is a 6 spoke. You have to remove the steering stops on the bottom yoke. 1 Quote Link to post Share on other sites
Chuwachi 0 Posted June 3 Author Share Posted June 3 Cool! Trouble is idk how that set up would go with a 4th gen, the leg lengths are what I need to find out... Quote Link to post Share on other sites

From searching this forum and seeing other people mods, i changed on my 4th Gen VFR to RC51 SP1 forks, detailed info: Honda RC51 SP1 Forks - The Forks are from memory 2-3 cm shorter but no problem on clearance travel. Triple from CBR 929 - ( CBR954 i think it's the same part) - With roller type bearings of CBR 929 CBR 954/929 Top Yoke - With roller type bearings, the original ball bearings would make the triple shake over 100Km\h. The Roller type bearings are a bit "taller" and the clamping is tighter, no problem after that. Honda SP1 Wheel CBR 954 Calipers and master cylinder Honda CBR1000 RR 2006-2007 Front Discs - Alternative option to the SP1's LSL 2cm "raised" Clip-ons - Installed right under the top yoke - Would smashed the instrument panel gauges - ( i want the maintain the original cluster gauge and functional) - Modified the panel, by cutting the 3 supports stem's and sitting it lower on the bracket CBR 954/929 - Front fender Fork bumper-stop - The turning radius is smaller but only drama is when moving bike from stationary to park it.

RC36 7 Posted June 30 Share Posted June 30 1st gen R1 or K6 GSXR600/750 forks are about as long as it's gonna get. The latter having the better internals and radial calipers. Offset is much shorter on them though Quote Link to post Share on other sites

The tubes on my 4th gen need a retirement plan ... please share or link to your thread Here is what I have... keep in mind, I bought the bike with this frontend. This is what I have found through some digging: 2004/05 600/750 FORKS (length ~712mm center axle to top of tube) gold/chrome legs, gold calipers300mm rotors (I made custom spacers/bearings to run the vfr wheel and stock 296mm rotors)850 springs 2005/06 1000 TRIPLES 30mm offset, 207mm spaced, 50mm top clamp and 54mm lower clamp, 28mm bore (have no idea about bearings, but I assume suzuki upper and lower) I believe I have 09-11 1000 lower clamp w/ an 06+ 600/750 top clamp. They have the same measurements as above just different color and key location. The previous owner mixed and matched I guess. Here's a link to how I found this out: https://www.svrider.com/threads/gsxr-fork-information-permutations.135430/ Hope this helps Quote Link to post Share on other sites
monstar 16 Posted September 11 Share Posted September 11 Don't mean to thread jack but since we're on the subject, are the K5 1000 or K6 600/750/1000 forks longer? I'm not sure if I'll keep the suzuki frontend longterm. That all depends. Are the RC51 forks that much better than my K5 600/750 forks given both have been sprung and rebuilt for my purposes? My idea in the meantime is to change my triples to 929/954 and use the gsxr forks I have. See what kind of adjustability I have with the bike geometry and go from there. I kinda want to use as much Honda parts on my honda if I can though so may at some point go RC51 forks. Quote Link to post Share on other sites
