It isn't just a "BOLT ON" job.

Your bike looks great......and I agree.......if your goal is to ride rallyes or do 70 mph down desert fire roads.

These long-travel mods are, however, fraught with their own somewhat substantial problems.

First, the forks must be re-sprung and likely re-valved. Depending on their axle off set and triple clamp dimensions they may significantly alter the front geometry.

They then must be examined under full compression to be certain that the front tire doesn't slam into the frame downtube, crashbars, triple clamps etc.

The standard front wheel, brake caliper and master cylinder may not play well with the new forks and then those components have to be changed. If you prefer a low mount front fender, mounting points will have to be fabricated.

In the rear, simply flipping over a suspension link (something I don't believe we can do with the PD06 models in the US) may, indeed, give you the ride height that you want but do you have any idea what you might have done to change the rising-rate geometry in the rear suspension?

Then there is re-springing and re-valving the rear damper to take full advantage of the increased travel and rising-rate changes you've made.


If all you are concerned with is getting the forks set up for your weight and eliminating some of the front fork dive, there are much easier ways.

What have others doen to fix this problem in the past? Do I need fork springs? or do I need fork valves?

If I'm taking my forks apart what else would you reccomend I do whilst theey're in pieces, I'll replace seals obviously, what else?
Or you can handle it the way I did:

Get Wirth progressive fork springs! My Honda TA is a 92 model and after changing the front springs - what a surprise!! At least it comes somewhat cheap, too!

Nice job thepoddo. Nothing wrong with modifications to fit your style of riding.

Last December, I bought a 1996 Transalp XL600V. I really love the simple handling and the V2 engine.





In march I started modifying it with a friend. Our aim was to rejuvenate it, both in looks and (offroad) performance. First we started with a rised handle bar - very important for my 193cm.



We installed this rally fairing, made by AfricanQueens based in Germany. The mounting required a bit of improvising, but we got it done. I can deliver some detailed pictures of the mount later if anyone's interested.







The next step was replacing the old suspension with some new stuff made by Hyperpro. Me like!





The first test ride with my new bike.



The riding is great. The suspension provides a lot of feedback but it's still dampening the worst stuff. The weight is barely noticeable while riding.











Today I mounted some knobblies for a dirt ride this weekend. I am very much looking forward to it! So far I think I can confidently say that I could keep up with any KTM 690 with my Transalp.



I still have some work to do, for example a proper bash plate, barkbusters, repainting it and a few minor tweaks.

Oh and it's a lot less heavy now. With a full tank (~18l) and oil it weighed 210kg before the conversion, now it's only 191kg (462 to 421 pound).

I throughly agree
still, after more than 2 years on the reversed rear link (something you can only do on the 650 model), and 2 months of longer shock and forks I have to say the steering geometry feels substantially unchanged and daily commute apart I already had the chance of riding the bike without any problem both on nasty mountain trails and on the tracks of the Italian Baja (after the race, obviously )

I am not here to say that what I have done is a work of science, nor that I really knew what I was doing.
Still, once I got all the parts I needed, everything has been pretty much bolt on and feels like a straight upgrade from stock

quoted for truth, but I have to admit that after spending a lot of money on springs, valves and oils I have never found the stock forks suitable for safe riding, not even on asphalt

Great pics of your countryside. And a great job putting that TA on a weight loss program. I like all your mods. I've heard alot of good from the Hyperpro products and how they transform the bike. Good job.

I'm in the process of removing the rear shock and have gotten stuck (literally).....
I've removed the bolts as per the manual but can't figure out how/where to slide the shock out. It's jammed in there pretty good. What simple thing am I not thinking of?

Never mind, had a neighbor come lift the rear wheel while I kept the bike steady.

Yep lift the wheel

I knew instantly what the problem was, we all asked ourselves that question once, so what shock are you installing?

Hi Mark! I went with the Ohlins but am thinking they may have sent the wrong one. There's almost an inch of difference in length and not in a good way...
I saw a reference to US/non US in another post. 8is this the issue or am I over thinking here?

Ordered an Ohlins this year too! Yes thats the same one I got and it is physically shorter but dosnt sag like the stock shock. So no loss. It will perform awesome. You will just need a hardened bolt and nut as the bottom shock mount is not threaded like the stock shock. Enjoy love mine
