Default questions about extended fork cap

Hi Guys i saw this extended fork cap on ebay but i can't understeand how they works,they make the fork longer? so if for example the cbr 1000 fork it's shorter than the 954 fork with this extended fork cap i could fix the problem and have the cbr 1000 fork long as the 954 fork? (sorry for the gsxr photo) here is the link on ebay: http://www.ebay.com/itm/Extended-For...sTHGnA&vxp=mtr

Yes, that's how a lot of people fit USD forks on older bikes with RSU forks and keep the geometry the same.

I've seen the ones you posted and then I recently was looking at these for the bandit (but they're really expensive)...
Hayabusa fork extensions



Yoshimura makes some albeit only 15mm or so....




Another route is getting custom fork tubes made. If you call racetech or someone, they can dial everything in for you.

Those fit only hlins forks and stock forks with hlins cartridge kit. But they are pretty simple so a machine shop should be able to make a longer cap to the stock forks from billet aluminium with no problems. 1000RR forks will work on 954 in stock trim allso. I would just get adjustable ''dogbone'' to lowet the rear same amount to keep the balance of the bike. 04-07 1000RR has allso 20 mm less fork travel( 100 vs 120 mm) then 954.

The internals on bouth stock forks are pretty much the same so why do you wan't to change them?

thanks for the answer guys,mika i want change the forks to have the radial bottom,i had another 954 before this with the forks of the cbr 1000 and i was very satisfied with the brakes (i know that the stock brakes of the 954 are great,but with the set up that i had on the other 954 i was feeling much more better),i wanted use those caps to balance the bike without move the rear,many people told me that the bike it's unbalanced with the forks of the cbr 1000,and when i saw those extended cap i thought that i could do the same with the stock forks of the cbr 1000,or if i will find one cbr 1000 crashed forks i will just swap the bottom on the 954 fork,but im not so sure about the second option because here i can't find a good mechanic,and if i will tell to them to do something like that,the answer is that they don't know how to do it (exept that they look at me like im an alien),by myself i can't because i don't have a place where to work, plus i don't know if i could make a good job

I don't like the brakes on the 1000RR. I owned a 05 1000RR before this 954 and my opinnion is that 954 brakes are much better. That's why i use the monoblock Nissins with the 1000RR forks. And you are right on the bike been little unbalanced. I have 1000RR forks on my 954 and the rear is at stock height. I'm going to try will it be little better when i get the rear lowered allso 20mm-30mm. Main reason that i changed was the stock springs on bouth forks but i thought about changing the bottoms to the stock 954 forks to get it back to stock height and getting springs and valves to them or a cartridge kit from K-tech but they aren't cheap

unfortunately yes,the cartridge for the forks are very expensive,i want try to don't lower the bike in the rear because i don't like how she will look after,i prefer do kind of job like this extended caps,(for this reason i opened the topic,because soon i will swap the forks) someone even used the gsxr 1000 forks (i don't know if it's shorter than the 954 or not). Mika you that you did already this job,for swap the forks i have to change also the brake lines right? do you remember how long must be the brake lines? some weeks ago i changed them on my 954 ( because i also fitted the radial master cylinder from brembo) and seems that are a little longer than the normal,so maybe those brake lines are good unless if the ring where it go the bolt it's different on the radial calipers

There's a lot of forks you can use. A lot of custom sites have charts detailing fork dimensions and specs. You're not limited to Honda stuff...
