I'd like to raise my bike a little bit, because I'm tall, and also because I think it will look good.

However, I have no complaints at all about the suspension front or rear, and I don't want to spend money doing it.

I know how to handle the rear; make a new "dogbone" connecting link, a little shorter than stock. I might take the time to measure all the link distances and draw it up on the computer to figure out how much shorter to make it for 'X' number of inches taller.

However I do not know how to handle the front (and in fact there may not be any good way to do it). Ideas I've had are:
Just loosen the triple clamps and lower the forks (this is very limited; I don't think I'd wanna go any lower than about half-bite on the top triple. I'm sure some would even say that that is crazy)
Machine a pair of "extenders" out of aluminum. These would have a 39mm OD male solid round top section (to fit in the triple clamps), and then a 39mm OD female section at the bottom with a slit up the side and a pair of bolts to act as a clamp (see simple drawing)



Machine new axle clamps which would clamp to the bottoms of the forks, moving the axle down an inch or two.

All of these would create problems with the speedo cable and the brake line, but I guess that's the nature of extending your forks.

I guess the other idea is just to buy a set of forks from another bike (I seem to remember that XR400 forks would work ??), but I do not want to get into changing triple clamps and front wheels. I've done a lot of work on my wheel (OK, paint is not THAT MUCH work, but it was a PITA and I don't wanna do it again!) and I also made a fork brace (which I don't wanna re-make) and my headlights mount to the bottom triple clamp, etc. etc. Machining the clamping bores on the triple clamps to go 1 or 2 mm bigger wouldn't be a big deal, I don't think, if there was something that could work.

I welcome any and all thoughts on the above musings....

Thanks,
Christian

Christian:

How high do you want to go with your bike? I agree the rear is easy. I think you would do better either changing the shock to a longer one or extending the stock shock attaching point. Around here for a while it was all the rage for KLR owners to lower their bikes for alleged handling and ride height issues. They would just change the dogbone to do it. It was later discovered by the more astute of the bunch that it changes the ratio of the rear suspension and softened it too much. A friend of mine changed his back to stock after riding thousands of miles on a lowered one. (bought it that way) He was amazed at the difference. I have a spare XR shock if you need it, it is about 1/2" longer.

I have put two different sets of forks on my XL, first XR400's and then CR125 USD,s. The 400's are easiest since they use the same bearings and stem size. The wheel is easily adaptable with a custom built axle, or bearing changes. The bearing change also requires a larger axle sized speedo drive and bearing spacer. You might be able to bore the original, but I lack the skill and machinery to do it so I got one for an XRL off eBay. As far as mounting the gauges goes, I discovered an easy way to do it the second time around on my USD conversion. It is pictured a few pages back on this site, reply 8175, page 513 and 512. That was the hardest part of the fork swap I thought, coming up with a way to mount the stock gauges. I pondered many ideas in my mind before I suddenly thought of an easy way to accomplish it. I used XR650L speedo cable and front brake hose to allow for the longer length on the USD,s. I have an XR400 fork brace I am not using now too, Forks also for that matter, I am very happy with the USD's and don't ever see going back to conventionals.

Dave-

I'll totally take the XR shock! THANKS! I'm guessing that 1/2" at the shock equals 2" or so at the rear axle, right?

I will pm you with my shipping address, let me know what I owe you.

As for the front.... I guess I will start poking around looking for some XR400 forks, while I also ponder other no-money options.

If it weren't for the odometer, letting me know how many miles I'm putting on, I would just give up on the speedometer. I'm using a GPS now to know my actual speed, and the stock speedometer is jumpy and noisy and generally annoying.

I welcome other ideas for raising the front...

Once again, thanks Dave!

Yeah... except I also really like the way the raised XLs LOOK. I think they look bada$$.

Plus I also already have the vibration dampening ROX risers (which I love)

How about some XR600 forks? I have a FEW sets laying about.

XR600 would work well too. I think they are the same diameter as 400 forks. I have a spare set of 400 forks, but I think my 400 fork brace fits 600 forks too.

Steve, what are you looking for for a pair of those XR600 forks?

(I'm sure this has been covered before, possibly ad nauseum, but...) what diameter are those forks? What length? and how much work to use my XL front wheel?

Thanks,
Christian

Yes they are the cartridge forks. I will have to measure the diameter and length. How about $100.00 + shipping?

To work with your XL wheel you will need different bearings, seals and hub center collar/spacer. And a later ODO drive which I have a few of. The later wheel uses a 17mm axle. OH, you'll need an axle also. I should have that too.

Too much??

I measured the forks on my son's XR650l. Same forks. With the bike standing upright the forks are 40" overall. Axle to top of fork is 35". Upper tube diameter is 43mm.

I just measured 400 forks. 43mm tubes, axle to top of fork 36 1/4".

Out of curiosity I measured the CR forks I just installed and they are 36 3/8", though curiously I am running them at 35 1/4" static sag with XR rear shock and the tubes sticking out of the top triple 5/8" About the same overall sag as I ran the XR400 forks, with it's tubes 5mm out the top.

Seat height at static sag 36 1/2"

Xr rear shock from axle to rearmost bolt hole on frame 23 1/2" full extension, 22 1/2 static sag.

compare those to stock heights to get total lift
