Front end conversion idea - thoughts?
Hey guys... This is my future plan for my front end upgrade. Regardless of your opinions on this particular conversion, please share with me whether my plans have any holes or problems... Right now it's just a theory, but i think this could give me a nice, budget front end, with powerful brakes, maintaining the narrow front fork spacing to clear the fairings...
93-97 cbr900rr triple clamps
98-99 cbr900rr fork tubes
Cbr600f3 17" front wheel
Cbr929rr brake calipers
97-98 Cbr1100xx 310mm wave rotors
Thanks!
James

should work, though you may have to shim the calipers or rotors slightly....900RR forks work very well on the VTR.... don't forget to get a decent MC (preferably radial) for the brakes (a late model OEM Ducati/Brembo works very well with 929 calipers....)
Good luck

If I was going to do it which Im thinking about is go CBR1000 USD or GSXR USD. If Im going to do it I want to do it properly. My thoughts are if Im going to do it may as well do it right.
I reckon a stock fork with a brace is is just as good as a CBR900 fork.

i too wouldnt bother with the 900 stuff . a good 04-15 blade front end be best . why replace old out of date suspension with old out of date suspension.
i have a full 929 blade front end on mine as i got it free . if i was to do it again id have gone for the 06 front end and had the forks revalved and new springs .

Not sure about that. There are multiple threads talking about someone fitting a USD Paoli fork years ago and finding it was too stiff for the track... Not to nay say anyone doing a usd conversion....
To get this thread back on track: I was just wondering if anyone saw any PROBLEMS.sith my wish list... Like if something doesn't fit right or something... Not really looking for critiques on whether it's better or worse than a USD setup...

I suggest you write Roger Ditchfield to test your theory and report back...
now then, back to the topic at hand, the only possible problem would be regarding spacing the rotors in relation to the caliper. However, the fact that you are using axial calipers (instead of radial mount) does give you some provision for making adjustments in this regard so it shouldn't be difficult to overcome, assuming it even is an issue...

Spokes that's no logic. On a track a bike is like sneakers on a basketball court. They may be nice but all the speed is the rider.
I have beat ninja 1000s on my ninja 500. And it wasn't because the forks were any good.
You should do your fork swap if that's what you want to do. I just feel like if I did that then in a couple months I would wish for CBR forks so would just do that the first time.
Guessing you already have all the stuff? I mean, what about, say, this?

tempting, huh?

I feel the same about the brakes, with HH+ pads and braided lines the thing stops brilliantly. Ton of feel and power.

Take into account the ratio of MC to caliper. This thread has dimensions of common swap MC and calipers.

Also here is a chart that might be helpful.

It was worse when they were riding RG150's. With their little narrow tyres (castoff 125gp slicks) and a fearless rider they held a really disturbingly high corner speed...
If you followed them close enough you could see the rear end pogoing through the loop at Teretonga as the cheap suspension loaded up and unloaded.
No wonder them nappies were full...

As for the threads original question, I think it sounds like a great idea. Lot of people have gone the 900rr forks route, and there's not much people have to say bad about them.
What size was the original disks on the 900rr? or the 929?
You might have to put the thing together to find out what size disks you need, or if you have to put the caliper on a spacer plate to match the disks you have...
I would be tempted to use the 900rr calipers, so you know what you are working with from scratch.
I am putting ZX10r forks on mine, using stock calipers, so I know I 'need' 300mm disks from scratch. I am using the stock VTR front wheel, so I should be able to get away with the stock 298mm front disks...
