Jordan p, the bike looks great in all black, i like it, nice and simple.

Just wondering what rear spring rate you guys have used when the rear of the bike is loaded up with touring kit.
I'm guessing a total of 20-25Kgs of kit (inc pannier frames & rear rack) added to the rear of my bike ('2000 E)

When touring i switch to S rear sub-frame and wind my standard spring up loads to re-level the bike but for next year I'd like to put a better spring on so I don't need so much pre-load.

I'm just trying to guess at what rate of rear spring I'd need...

Dude, where is Canyon Country? I'm in the bay area, and I want to ride the crap you are riding!

[150ron]

Canyon Country is in Southern Cali, about 25 miles from Los Angeles, if you are ever out there, let me know, theres tons of off roading all around me,



Some of the black diamond trails are , im not gonna lie, just looking at some of the climbs scares the shit out of me




Anybody put a Trail Tech tachometer on their DRZ? looking to put one of those on mine, id like to see some pics.

I'm down in Orange County all the time but rarely bring my bike since I sold my truck... might be getting into another truck shortly though...

Really! Is that the best you can come up with? That video doesn't even begin to support your theory that riding on the balls of our feet will break ankles let alone provide proof.

Whatever... I am done arguing with an idiot.

The same spring that you would use for the your weight and no luggage - just add extra pre-load. The Racetech calculator is good for your purposes.

The short version for this is that your rider weight has not changed so the number of kilograms and millimetres between static and rider sag has not changed.

You'll want to add a little extra damping to the mix.

Great, we are only about a hour apart, im right around the magic mountain area, and the trails are about 7 miles away from my place, if you ever can get your bike down here, let me know, and we can hit some grea trails, i usually hit the trails every sat or sunday morning, theres some awesome stuff out here.

what is the story behind 4:29 ? looks like the rider knew the hill ended, or maybe it was a jump he chickened on ? I sure as hell would have

Heres mine. Im not thrilled at the quality of them, this is my 3rd one, but they do the job and are cheap enough.

Yes that hill was scary, my buddy thought it was a jump but he realize last second that it was a death trap... so he bailed his iron horsewith couple of pee drops in his Fox pants.

Hmm, I'm not so sure... I did this on the WYOA 2012 trip and it beat the back end of my bike loads - loose spokes, wheel bearing shot, swing arm and linkage bearings had play. This was with a rear MT21 running at 25psi.
Next time I'll run at 18 to add a little extra cushioning.

Thing is your suppose to match your bikes springs to your weight anyway - I'm about 1 spring on the light side for my rear now but the front could do with being harder. Adding luggage weight (as far as your bike is concerned) is like having a light passenger. It needs to be taking into account I'd guess...

When setting the rear sag there is only so much your suppose to do with the pre-load, after that the race sag messes up your static and highlights the fact the spring isn't right. That is what happened when I adjusted my pre-load to re-level my bike. In the end I set it at the best compromise but when there was no luggage on the bike it was literally hard against the stop - no static sag at all.
That is probably okay I guess but just highlights how much pre-load was needed.

TBH it just surprises me that so many people load these bike up with luggage without at least changing the rear spring. The 'S' has a slight harder rear spring (as it is rated for passengers) so maybe that alone is enough. Not a massive difference though. 'E' spring is 5.3kg/mm and 'S' spring is 5.5kg/mm.

There's always the exception that proves the rule.

When riding thru big rocks or other obstacles at foot height, always ride with the ball of your foot on the peg. If you hit something, it will only knock your foot off the peg, rather than wrapping your foot around the peg breaking a myriad of bones and doing massive ligament damage.
