4th gen usd forks, best and easiest fit?

Recommended Posts

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.

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.

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.

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.

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.

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.

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
