749/999 forks to 916
 

Hi
Does anyone know if i can fit 749/999 Ohlins forks to my 916, and if so, what would i need.

you just need the correct sized yokes to go with the forks the 999 ones will fit but obviously look different to say a later 748R that would then look like the 916 ones.......

the mudguard mounts are different and you also need to consider what your doing with your brakes.......offset and calliper mount........

As Andy says, yes they will fit with a few considerations.
Main thing will be the 56mm bottom Yoke.
Are you going with axial or radial caliper mount forks.
Disc offset i'm fairly sure is different, not a real problem if using axial calipers and the 916 wheel and discs but you will need 5mm spacers between the Calipers and the fork legs

ive actually got a 53 56 748r ohlins top and bottom yoke set sitting in my garage........

Andy your probably going to get a few PMs, emails etc now

well i kept them because of the ltd plaque on the top yoke.........when i fitted 30mm offset mag ones but hey im mercenary enough to sell..do you think they are rare then......he hee

Well more and more 748/916/996 owners are going to Ohlins forks these days especially for their trackbikes, so not so much rare as greater demand

So basically am i right in thinking that if i were to get a set of forks complete with yoke and bottom clamp/stem i'd be half way there. I've just bought a pair of new 65mm calipers (not radial) so i'd just need to do a bit of engineering to put it all together.

yep, a few alloy spacers and your nearly home

I could be talking rubbish, but are the 749/999 forks a different length to 748/916 ones???



Chris:burn:

It wouldn't really matter if they were as you would just have more fork above the yoke to get it to the correct geometry - obviously within reason!

It's the fork TRAVEL which is the important bit!

I think the ST forks are only about 20mm longer than 916 ones, and it's all in the fork body as the travel is the same. Chances are that the 999 ones are close enough not to make any difference, but don't quote me on that!

Thanks for the advice guys
will look a bit more into it before i proceed.
;)

Which ST Forks is that Ant as I have just put a ST fork next to a 748 fork and the ST fork is 20mm shorter, but offers the same amount of travel.

I no longer have a set of 749 forks here but from what I recall they were the same length as those for the 748/916/etc

I was under the impression that the 749/999 series was shorter, or was it that the yolks would need changing as well??


Chris:burn:

Yes and no....

Just measured them:

749R Ohlins:
Fork body (gold bit) L = 500mm
Top of Fork Body to spindle C/L = 685mm

996 Showa:
Fork body (gold bit) L = 480mm
Top of Fork Body to spindle C/L = 685mm

Hope this helps.

Ricky is that preloaded with them in the bike

Out of the bike I measured mine as

998S Ohlins:
Fork body (gold bit) L = 500mm
Top of Fork Body to spindle C/L = 720mm

748 Showa:
Fork body (gold bit) L = 480mm
Top of Fork Body to spindle C/L = 720mm

Kev,

Yes, I measured them preloaded in bike(s). I'm afraid that I am not as dedicated as you as I didn't take them out to measure them!! ;->

Not dedication just measured the ones lined up in my hall way, I just haven't got any 749/999 forks about at the moment

^^ I've not got any information to hand on the 749/999 models, but was prety sure that the fork length was shorter on those models... :confused:

OOOH!
Looks like i've stirred something up here :D Thanks for all the help, another thing i was thinking about was to bet my Showa's serviced and while i was at it, get the legs re-anodised Ohlins gold (cheating here ;) )and have the chrome re-done with a black DLC. Maybe even just get the bottoms aqua blasted and laquered. I know it's not the real thing, but it should look pretty :rolleyes: until i can hide enough money for the real thing. Already have a new Ohlins rear shock.

What say you guys?

As before...a comparison of 749 and 996 fork lengths..

749R Ohlins:
Fork body (gold bit) L = 500mm
Top of Fork Body to spindle C/L = 685mm

996 Showa:
Fork body (gold bit) L = 480mm
Top of Fork Body to spindle C/L = 685mm

Excellent... :D

and adding to the confusion, what are the chances of 996 forks fitting 749/999 yokes - is it just a question of fork diameter or is the width between the forks different between 996 and 749/999 yokes?
sorry for asking, but since we're on the subject.....cheers!

James I'm pretty sure they are a straight swap.
I did have a set of 749 forks and yokes at one time and from what I recall the fork spacing was the same as was the fork diameter where they fit in the yokes at 53mm for both top and bottom yoke

Certainly is a sweet looking bike

cheers loads for that mr skids. Since the 996 has just been sold there's a gap in my garage that's rapidly being filled by the jigsaw puzzle that is the hawkati. I'm goingto try and get as much done as possible whilst waiting for flat sale and forthcoming 998s which i'm gunning to get.

Well, after much humming and argggghhhing i decided to go for broke and got me some Ohlins forks. Worked out that by the time i did all i wanted to do to the Showa's, it only cost a couple of £100 more to get the real thing. Now all i need is the bottom yoke and stem...............;)

I fitted a set of Ohlins R&T radial forks off a 999R onto my 748 using the stock yokes. You just need to get the bottom yoke bored to suit. I know someone that can do it for you based in the South East. He did a superb job on mine.

I then sourced a set of 15mm offset discs and had a spacer made up for the wheel spindle to get the alignment correct. Was actually very simple to do.
