- How to adjust your shock’s preload to smooth out bumps, control body roll, and affect traction.
Having manufactured the largest, most diverse lineup of sport ATVs for more than 20 years, no other company is more dedicated to the market and exhilaration of sport ATVs than Yamaha. Now, we’ve taken all of our riding and racing experience and put together the “Yamaha Sport ATV Tech Tip Video Series” to help you get the most performance and reliability from your ATV.
Smoothing bumps, enhancing traction, and much, much more is why most riders would agree that no single aspect of your ATV's performance is as important as its suspension. Maybe that’s why Yamaha has become a leader in nearly every sport ATV class, from the championship winning YFZ450R to the king of all-terrain, the Raptor 700R.
Most ATV shocks offer some level of adjustability with many offering preload adjustment. High-end models like the Raptor 700R and the YFZ450R also benefit from shocks with high and low speed compression damping, in addition to rebound damping adjustments. If you have never tuned your shocks, all of these adjustments can be a little overwhelming. For now, we will start with the most basic and common adjustment, preload.
If you have any questions about tuning your ATV's suspension, you can always count on your local Yamaha dealer.

From a high end offroad racing standpoind, I always belived coilover preload only affects ride height and spring force, and adding more preload actually makes the spring softer because you are compressing it ?, From what I have learned springs should be as soft as possible while all tuning should be on the shocks because shocks can react to different forces , low speed, high speed, low force, high force.
I have a raptor 660 if I’m drag racing I should set my front shocks to the softest setting for more traction?
what adjustments does the raptor 700 (not 700R) have?
What do u recommend for shock adjustment on a Yamaha blaster to help absorb the bumps so the ride isn’t rough
Kyle Trautman what year is your blaster?

What if i loosen it up will it be easier to pop the front wheels off how can i make it easier?
How Can I lower my front end on my 2020 raptor 700r se??
hey , I have bad english , if I want good traction for drag racing I go clockwise?? , some one explain me please
+zaji7 If you want more traction, turn the spring preload counterclockwise or to the left to soften up the spring. A softer spring will allow more weight transfer improving traction.. This includes traction for drag racing, or traction for corners. The drawback is that if you go to far, the shocks will bottom too easily, you could get too much body roll in the turns, I hope this helps. Let us know if you have any other questions.
ATVonDemand got it , thanks a lot for your answer , you just didn't tell me what to do , but explained it perfectly , thanks again.
Awesome.
so u do that for the front and rear springs for more traction ?
Ok I know this was a Yamaha shock video but I have a 2007 Suzuki LTR450 and it won't start the electric start doesn't work anymore I have to bump start it and then even once it's started it doesn't stay running unless I rev it for a long time or ride it. Is this a wire/valve issue if so how can I fix it or do you guys know a good video I could watch on how to do it.
Thank you!
Not sure on this one.
The battery is dead. Replace it.
The carburetor could be garbage, it might not be getting the right amount of fuel, or its receiving too much. Thats easy to check though, so I'm sure its not that. It might be the battery or some wiring issues. The worst thing it could be is you might need to fix something inside the engine like a top end rebuild but I REALLY doubt it. So yeah, I would replace the battery anyways.
i have a 14r i just ride trails with lil jumprs i want to soften the shocks,whats should i adjust
What are you trying to accomplish? Do you want a stiffer ride or a softer ride? Besides preload which was discussed in this video your machine has high and low-speed compression damping up top on the reservoir and rebound damping adjustment at the bottom of the shock. Here's the quick and dirty. Starting in the middle, if not the factory settings, if you want a softer or firmer ride over things like roots, small square edged rocks, and square edged holes, adjust out or in on your high-speed compression. If you want your suspension to be softer, or better resist bottoming on jumps and g-outs, back out, or go in on your low-speed compression damping. Typically, we try and run as little rebound damping as possible without having the machine kick or bounce. Running too much rebound damping will make your suspension pack up in whoops, not allowing it to fully recover before the next bump which will result in the machine bucking, swapping, and all sorts of unpleasantness. When you adjust your suspension, the general rule is to make small changes, one or two click or a quarter or half turn if there are no clicks, and test the ride. Check your owners manual if you arent sure where the adjusters are located on your shocks and which adjusts what. Hope this helps.
ATVonDemand yea trying to just make my ride softer more comfortable
If you keep stock shocks on a raptor 350, could you still do jumps real well or should I put aftermarket? Thanks
+Xe Nukka Good question. With your front shocks not being rebuildable, if you are exceeding the perfomrance capabilities of the stock shocks and their adjustment you may need to upgrade. Truthfully the Raptor 350, or Warrior, and any sport ATV with non-rebuildable front shocks was ever really set up for big jumps. If you have your spring preload maxed out and you are bottoming out often, its time to upgrade. If your not bottoming your shocks often than you might able to hold off for a while. Here is a link to an affordable aftermarket shock test we did on a Honda 300EX that we know from experience works quite well on the Warrior/Raptor 350. czcams.com/video/G9Idf4Kahzk/video.html Works can build shocks set up for jumping and have more affordable options than most other shock manufacturers.
+ATVonDemand Could I get away with only front aftermarket shocks till I start racing? Or buy front and back? Also I am new to this stuff but could you put a different brand on the front shocks and another different one on the back? And why type of shocks are good for all around? Thanks!
You contradict yourself when you talk about preload ... They change RIDE HEIGHT not Shock stiffness , as you LATER state...
On zero preload, or many aftermarket shocks, preload primarily effects ride height and has little effect on stiffness.. On standard preload style shocks, like almost all OEM shocks Adding preload will more dramatically effect stiffness, or ride quality while also effecting ride height . Sorry if we weren't clear enough.
+ATVonDemand I have been trying to completely understand the effect that preload has.. I run Elka's and I noticed that they don't react excactly the same as oem , but the effects are similar. Basically , preload adjusts mostly Ride Height though..This in turn effects handling and shock "feel" , and center of gravity .
But the shock "stiffness" remains constant , unless you adjust Highspeed/lowspeed , rebound , or change spring itself.. ?
Thanks !
Yes. you are pretty much correct. If your Elka's are a zero preload setup,everything you said in reference to the effects of adding preload are true. On a zero preload shock if you want to have a noticable dffect on the firmness of softness of your spring rate you will need to change your cross over settings. This effects how soon your spring stack transferrs the load from your tender, or smaller spring, to the firmer or main spring. Keeping the load on the tender spring longer will yield a softer ride, while transferring the load onto the main spring sooner will yield a firmer ride. Compression and rebound damping are there to control velocity, not to make the shock stiffer of softer. Once your spring settings are right, then you dial in the ride with the damping adjustments. .

Motocross or cross-country?
