Hello There.



I fitted progressive springs to my KLR, and that completely transformed the bike.



I would like to do the same on the TW. I got the spec sheet from progressive suspension, and picked one closest to the TW stock. Part number 11-1107 Free length 457mm (18") OD 27mm (1.05") .45kgs/.63mm (35lbs/50inch) spring rate.



Has any body looked at this spring before? I have seen some serious front suspension mods on this forum, but I don't need to go so extreme. Its the wife's ride, but she does ride some sand whoops very now and again. The standard suspension also seems to deflect a bit too harshly when hitting small ruts at 80km/h on gravel roads. It will lead to tank slappers or the like, and I don't need to scare the wife off just yet!

Might give some serious thought to going through this process first http://tw200forum.com/index.php?/topic/2902-fork-oil-changing/ . Then you may look here for a TW 125 progressive fork spring. The 125 is the 'European' version of the TW200 just smaller engine. I bought the spring and was pleased http://www.hyperpro.com/index.asp?page=springkits . Gerry

I contacted hyperpro, but I have to buy through their SA agent. The SA price is $220 before shipping, which would be another $20 or so. A bit steep if I can buy the Progressive at $70

I need to change the front oil to something thicker any way first, as the damping is no good. After reading the above article, it seems I first need to set the forks up properly after an oil change, before I fiddle with the thickness of the oil!



Thanks for the input, this site has been a huge library of info and ideas. I will probably buy these progressives, and test them to see if they work. It would be a nice cheaper alternative if they do work.

Has anybody bought the hyperpro springs? If so what are the specs? Free length and spring rate?

I used both front and rear. I ride off pavement and am always looking for comfort. They worked fine for me, but then my mod expense was less, but greater than $70. Gerry

The black spring is from a Yamaha V-Star, the yellow is original and the purple is the Hyper Pro..

I did. I also added schrader vavles to the fork top caps (added 1 psi), and ATF fluid for fork oil and cut the spacers a little longer than hyperpro recommended for extra preload. All based on other forum members recommendations- notably Mr Gizmo and Lizrdbrth. In my opinion, it transformed the front end from something that felt way to undersprung and dangerous when I braked--due to front end dive, into a stable and effective front end. I think all the specs are on the PDF on the website. By the way, I'm a hefty 230 pounds at 6'.
