How Many mm between top of fork tube and triple clamp?


XXCANDU

Recommended Posts

Hi Everyone - Sorry it's been a while! :oops:

Anyways, it's time to get the XX back out on the road, it's been a long winter here.

But before I do, I wanted to raise the Bars a la Joe's suggestion's.

So I check out the top of the forks and find the circlips jammed into the top of the handlebar bracket.............no joy!!

I measure the mm between the top of the forks and the top of the triple clamp and whadda ya know............32 mm. No wonder it's as steady as a rock at high speed and I have to muscle her a bit through the twisties.

So I searched the threads and found where it is supposed to be 38.3 mm according to the manual, and that some have increased that to even 39-40 mm.

Is that correct?

What can I expect when I move them back where they should be?

Change in handling turning in for sure, but what about riding position?

Should I make that change before I move the bars up on the forks?

Any comments appreciated.....

Thanxx!!

I just measured mine. I have 1 5/8'' from the top of the triple clamp to the top of the fork cap. Not the part that you put a socket on, just the top of the cap. Sorry all I have here is an inch tape measure. My bars fill the space from the top of the tree to the base of the cap where the clips go. I had my bars raised on the tubes to 1/4" above the cap and it was good for me until I put the corbin on, but I found it uncomfortable with the corbin and put them back to stock.

Thanks Airborne900!

That helps, 1 5/8" is @ 41 mm, and by my calculations I have 34 mm to the top edge of the cap, the caps themselves are about 2 mm thick.

So, that would mean that my forks are at least 6-7mm too low in the triples. I think my dealer didn't set the right clearance when he put the Progressive Suspension on when it was new.

When you changed to the Corbin saddle, did you find you were too upright and is that why you lowered your bars back to stock?

I have a G/F & Lady Corbin that I bought when I got my '03 in Nov/03.

I like it, but my wife doesn't, says she feels like she's at the OB when she sits on it, she prefers the Stock seat!

Yeah, I think it put me back farther and a bit more upright. It made my wrists cramp up real bad like they were just at a weird angle or something. I just couldn't seem to keep the pressure off them. So I lowered the bars and now I'm more comfortable. It doesn't really make sense, but you know just do what feels comfortable.

My wife hasn't ridden on it yet, but I had her sit on the corbin, and she said it felt better than stock. Actually she thinks it's better than my 82 900c with a corbin. I'll have her check back in after a 300 mile day :lol:

The issue with my wife is that she is fairly long legged and with the stock seat her knees tuck in underneath my butt, whereas, with the Corbin, I'm lower so her knees are higher, thereby spreading out her knees on either side of my butt!

Great for sex, but not long rides! :lol:

Shorter legged people have ridden in behind, and have found the Corbin very comfortable, so it's just an issue between myself and my wifes physiques.......and I'm not about to trade either my wife or the XX - too expensive, plus long legs are good in other situations!! :twisted:

You'll know what I mean if you encounter the problem, she'll let you know in short order!! :wink:

You could just have her wrap her legs around you like they do on the choppers :lol:

My wifes about 5'2" so she should be alright. I'm thinking of getting the backrest for her. Have you tried the backrest?

I'm thinking it will help her from sliding off if I whack the throttle when she's not ready :twisted:

I don't think she would find that too comfortable in the twisties, something the Choppers don't take a shining to either!! :wink:

Yes, I got the backrest also, #297 if I remember correctly, like on their website, very nice!

It has a slight tendancy to push her forward a bit, but if she is 5'2" that shouldn't be a problem, she should find it quite comfortable. My son's G/F is 5'2" and it fit her like a dream! And it gives her a greater sense of security when you whack the throttle!

If you PM me I can send you a pic if you're interested.

OK - so I looked around somemore on the threads and found the one about "Hyperpro Springs" which discusses all about the measurements of the top of the forks!

http://cbr.geckobox.net/forum/viewtopic.php?t=18887

Sorry 'bout that, funny that the thread didn't come up when I used the 'Search' though! :shock:

Anyhow, there is more than enough info to digest on the other thread, and I already have the 'Hyperpro Springs' front and rear also!

Thanks anyways!!

Good Riding All!! :wink:

And how would you rate them compaired to the original? I stated once I could make turns with a very bumpy road-surface about 50% faster. Did you notice that too?

Actually, have had them since new, never have rode My bike without them, so it's difficult for me to compare. I had test ridden, at length a used '97 that my dealer had, and found the suspension very compliant, but I don't know if it had been modified also?! I also had ridden a '03 Demo before I bought mine, and the hobby horse effect was very apparent, that's why I bought the Hyperpro's and had them installed before I even took delivery of My '03.

BTW - I have raised the forks to 50mm between the yoke and the top of the fork as you had suggested, and, so far, so good! I haven't had a chance to really try it out on the twisties, but on the highway, at least up to about 100mph(160kph) there appears to be no difference from before.

The steering did feel a little lighter however, and it seemed a little more nimble, but not at all nervous.
