Hi Guys

I'm a newbe and over the last 6 months I have gone crazy and brought two 906s and a 907ie

The problem is the 907 has k100 forks from a bmw fitted by the last owner, he had a small acident,to my amazement he binned the forks for a beater pair, nuts, the bike preforms well and is still streight, a big bonus, I have explored fitting a pair of 906s forks on with the aid of an adaptor and some 10mm spaces to lenghten the forks, the guard can be raised to meet the 17" wheels, All achieviable but not original.

I have been on the hunt for a pair of 907 forks and to date have failed to locate a sorce

If you Guys could point me in the right dirrection i would be alot happier.

Thanks Peter

welcome to the site and congrats on your excellent choice of bike purchase
with regards to the forks there are a few members on here that have complete forks for sale and also there is ebay - however they are a little bit like rocking horse shit and also you can expect to pay over $400+ / £500+ / E700+ for a reasonable second hand set.

It now sadly is starting to look like it would probably be more cost effective in some cases to actually buy a full non runner, if you can find one? Then part it for yourself, those type of bikes are also pretty rare.

where in the world are you it might help knowing to see if anyone is local who can help?

First thing is to ask the previous owner if he still has the bent or damaged 907 forks. Most often, the tubes get bent, which can be straightened by a good shop, or get new tubes made by a company like Forking by Frank.

The sliders on the 907 forks had the caliper mounts for the 4 piston Brembos. I think the K100 had the 2 piston F08 calipers, like the 906 has.

Out of interest, what size rotors does he have on there now? I know that some BMWs used the M1R fork, and that's probably what he used. Otherwise, he would have had to change the triple clamps also.

Can you post a picture of what you got and we might be able to comment a bit more.

But as it was already mentioned, finding a set of 907 forks is rather a good trick. Not many around, and in high demand. I paid $300 for a set. Everyone with a Paso who wants to go to 17" wheels sees them as a quick conversion, or guys building retro racers who want the 4 piston calipers and the old type forks.

If you are really diligent on e-bay, you might get lucky in about a year. Otherwise, buy a distressed 907 and part it out.

Cheers,

Hi Guys

I have come across a pair 0f 851 forks that might do the job, complete with triple tree's, however I was aware the 851 had 16'' wheels but had the upgrade calipers fitted witch means no adaptor plate the off set for the different size rotors may be an issue, so is lifting the guard up an option and is this a workable deal the other issue is the lenght I guess.

The rotors on my 907 are 300mm and have an adaptor plate fitted home made and not very impressive

I'm stuck in New Zealand guys, Yip thats Kiwi land

Cheers Peter

The 851 fork is rare find.

The 851 forks will be a bit shorter, and the travel is also less , about 100mm compared to the 125 of the Paso. Rumor has it the internals are the same, just different springs. You can probably switch out the stanchion tubes and springs have a good set up.

Also, the top triple clamps have 3mm more offset than the Paso. Rare as hens teeth. Sought after by the vintage racing crowd, so if you don't use them on your bike, you can get a good price for them on e-bay.

As for the 16"wheels, some did, some didn't, but they all had the brake bosses for the 40mm bolt pattern and the 4 piston calipers. So you won't need the brake adapter plate. If they did use the 17" wheel, then they used the same front fender and stiffner plate from the 907 paso. (its arched to clear the wheel)

Cheers,

The 851 forks will be a bit shorter

10 mm shorter.

Dunno about being stuck here, from what I have seen of the world we are in a f---ing good place ( if captian cook had done a proper job it would be even better ).What is actually wrong with the k forks , I mean apart from the fact they off a bmw ( ugh ). I have some engineering type drawings of adapters to fit the 4 pot calipurs ( both types ) to the 2 pot forks if that would help.
