Shock lengths/options for XR200R upgrade

Recommended Posts

Hi! My first post here. I'm in Nebraska and have recently bought three Honda XR200R's for our family to go biking. I'm 54... used to ride dirt bikes as a kid (just for fun, no racing)... and just recently discovered how much fun these XR's are. We have some 4 wheelers too, and we're headed to Wyoming's Snowy Range in late June for a few days.

We have (2) 2002 models, and (1) 2001. For the bike I ride (a 2002) I want more front & rear suspension travel, because the bike bottoms after even the most modest extra-terrestrial excursions. I weigh about 190 in riding garb. I've spent hours reading XR200 threads here, particularly relating to suspension, and it's been immensely helpful... thanks for all the background! I recently bought a pair of forks on Ebay that were advertised as being off an '84-85 bike. I figure on sending them to Race Tech for their treatment, including cartridge emulators.

My question for you guys concerns the rear shock. I've seen information stating that all pre-'93 models had the same longer travel forks and shocks (longer than later years), and 93-on models were shorter travel. I saw a shock listed for sale a while ago from an '81 XR200R, and the eye-to-eye length was listed as 13". The stock shock on my 2002 measures 13.5"... so the relationship between those two shocks seems backward to me. I know that because of the the pro-link suspension, shock length and stroke don't correspond directly to rear wheel travel, but I've also been told that I could install a longer shock w/o having to change the linkage parts.

Race Tech can sell me a whole new custom-built shock, and I'd be game for that... but at this point I wouldn't even know how long to tell them to make it.

So I'd particularly appreciate it if someone could tell me the uncompressed eye-to-eye length on an '84-85 XR200R shock. Beyond that, any other advice is welcome.

I guess I'll throw this question in, too: I'm assuming that "eye-to-eye" specs should be measured center-to-center (not inside-to-inside or outside-to-outside on the holes.) Does pretty well everyone measure center-to-center?

And... if anyone knows where I could pick up a good shock for this bike (in good shape or needing rebuilding), that would be helpful. Race Tech says their turnaround is around 10 days, and with a June 22nd trip date, I need to keep moving on these mods.

In my opinion i would stick with the stock travel and stay at least close to 13.5 shock lengths because a drastic change from 13.5 will cause a change in geometry and bike handling. If your goal is to control bottoming, i suggest a simple revalve would address your complaints much better than changing overall travel. Also, riding on a freshly rebuilt suspension improves ride quality like nothing else. I'm confident you would have better results finding a tuner and asking for revalve to type of riding and springs according to weight. It would be money well spent and would change the ride entirely for the better.

Actually, maintaining geometry is what I'm trying to do by trying to find out what the '85 model (and surrounding years) had for a shock length. I don't know if just being 2" further off the ground qualifies as "geometry", but I know I need to maintain the steering rake angle. I figure having the front fork length and the rear shock length converted to the pre-'93 setup should result in the same good handling characteristics as what the bikes had back then (plus having the benefits of rebuilt and/or new components.) However, I haven't learned the "trick"... whatever it is... of discovering the length of the earlier shocks. Race Tech doesn't seem to know. More time with Google, maybe...

Thanks for your suggestion.

      Hey guys. I recently purchased a 16 yz250x and the first 2 rides i LOVED the suspension. Then the day before a race i reset all my clickers to stock and everything felt like crap. No plushness at all and deflected off everything. I now have a 5.4 shock spring for my 190 pound weight and dialed in sag. Any recommendations on where i should go from here? Right now the fork is 12 out on comp and 15 out on rebound. Shock is 1.75 turns out on hsc, 14 out on lsc, and 18 out on rebound. Any help would be appreciated!

      Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the  weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump.
      Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road.
      However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road.
      In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.

      I was hoping someone could share the stock shim stacks for the forks on a kxf250 2012. The rebound valve nut fell off!
