Does anyone know if forks from a pre fuel injection YBR will fit a 2009 FI model?

They look the same to me, but I notice they make a point of putting what year they've come from so I don't know if they differ?

Someone must know Praying

Measure them? Same diameter then yes, different diameter then no.

Don't have them to measure, old ones are bent, and fixings may be slightly different

Am trying to have a look but thought someone may know

The entire things aren't bent. You only need to measure one small part of the stanchion to get the diameter of the thing. Alternatively you could measure the size of the hole in your yokes!

Then just get the person you're buying off to measure as well.

Any stanchions with the same diameter should be fine to use so long as you can attatch your wheel and brake calliper to the fork bottoms.

I can't see why they wouldn't fit to be honest. Unless the bike got redesigned to make it heavier/lighter/faster then they would have had no need to redesign the front end.

The forks on my GS are about twice as old as the bike Thumbs Up

I imagine they will fit, but I wanted to be sure..in fact i'll just compare pictures

You could email the seller asking the diameter of the stanchions just to be safe, but I would be fairly certain that those would fit purely by the fact that there's only 1 year difference between the bikes.

The most noteworthy change on the YBR happened post 2008 when it went FI, but both your bike and that bike are post 2008 so that accounts for the only real change the bike has ever had.

Other than that they introduced the more sporty/off road version in 2010 called the YBR 125 G. Although this change mentions no changes to the forks as a unit, just the mudguard and headlight, etc.

I can't garantee that they'll fit... but personally I'd buy those. On the small chance that they don't fit... put them back on eBay for what you bought them for.

Oh you have me mistaken, and 2006 to 2010 is 4 years not 1 Laughing I think you read the 6 upside down Cool
But my bike is 2009 anyway, it was more the before and after FI that I thought would differ as you say, i've bought ignition and bits for pre-FI for mine before that didn't work, after the seller said "Should fit!"

Not sure what year the forks i'm getting are, DMCpro on here is hooking me up, i've asked just waiting for him to get back to me

Gonna go for it anyway as it's a good deal from him Thumbs Up

Nah I read your bike as being 2009 and presumed you were looking to buy the 2010 ones! Smile

At the end of the day, if they don't fit, forks are very easy to sell as long as they're in good condition. In a crash they always get damaged so always need replacing. But obviously if they're always the damaged part in a crash... not many of the bikes being broken have them so they're always sought after Smile

I'd risk it to be honest and if they don't fit just eBay them for a decent price.

Do they fit if you put them in without the bottom-yoke?

Ask Paddy how much of a nightmare my forks were to get back in...

My forks are also more male then female as they were before. It's better though... the bolt on the top can be twisted to adjust the forks harder/softer depending on what you like.

Yeah I prefer that bolt, also these forks seem to weigh slightly more, they seem better in general actually

And no couldnt get them in, is awkward though

The bit with the bolt in fits but the actual stanchion that it goes into is like 1mm wider and doesnt go through, if that makes sense

bloody phone didnt come with the USB cable so cant upload pics Rolling Eyes
I thought it was the yokes being closed up so I opened them with a flathead slightly, didn't help, figured if I tried to prise it open too much it'd just derp the circle and make it a crushed oval and I wouldnt be able to get them in

What you're saying makes sense, yes, but it seems very illogical that the forks on later YBR models would have decreased by 1mm on a bike that really hasn't changed.

Personally I would try prising them open a bit to see if that works. To get the gear lever off of my GS500 I have to hammer a flathead screwdriver the entire way down the gap to widen it enough to come off. Otherwise it gets stuck.

In the art of a bodge job I would do anything to make those forks fit if it really is only 1mm. Even widening the yoke holes.

Personally I'd get a file/drill out and make those yokes slightly bigger to fit the forks.

Sod safety Mr. Green

I'd offer to come over and take a look... but alas... no bike Thumbs Down And you're much further away than I thought because you moved you arse, and I'm lazy.

Now those are some bent forks.

My GF's SH300 (was my old SH300) has bent forks too, but they are less than 1mm out of true as measured from the centre of the stanchion compared with either end. Not visibly bent, you have to put one up against a straight edge to see anything. It adds up to more than 1mm at the axle though, especially because of how scooter forks attach to the steering stem - the two bolts that grip the fork legs are really close together.

And that scooter has noticeable handling problems going around corners - flops in on one side, wants to run wide on the other. Exacerbated on new tyres, feels better on more worn tyres.

I hope you weren't riding around that bike on those forks. I can only imagine.

Those forks will straightrn with no drama. Failing that, buy a different yoke.

Same as my Varadero, done 1000 miles since it happened, makes for lulzy commuting.

Laughing Obviously not. I got SMIDSYd and that was the result
I did manage to ride it down the pavement getting it to my parents from the crash site slowly and by holding the bar seriously hard as it pulled to one side, hurt my arm holding it like that Rolling Eyes


They might be able to be bent back into shape but I dunno, I'll ask the garage up the road I guess

DMCpro (the guy who I got the forks off) said he has the yokes if i'm interested, but not sure if they will fit without measuring, need a tape!

And yes it's all well and good saying they should fit, but it was also said these forks 'should fit' Brick Wall

As for the cheese metal spanner...not sure where I got it from, wilkinsons I think, which doesn't surprise me, cheap crap Thumbs Up

Pics help eh Wink

I thought about filing down the current yokes but...sounds dangerous! I don't honestly see what holds forks in that stops them from just sliding through the yokes as there's nothing on top of them to stop it, you could just push them through if the yoke clamps weren't tight enough, and if you overtighten them surely it will crush the fork Neutral
