Suspension settings for the Obese?

I'm almost 300 lbs with all my gear on. Would it be safe to assume that all the settings could just be to the stiffest settings or is that not necessarily true? (Stock 2007)

Are you talking track, or street?

You're going to need to get your suspension sorted out dude.

At a minimum get springs for your weight.

Going to give not the answer you asked for but now is a perfect time for you to get down to a healthy weight! You are going to be competing as an athlete, and road racing is not undemanding physically.

You will for sure need stiffer springs I would think but pace and riding style determine spring rate not just rider weight.

Just track days. I'm not extremely aggressive, just intermediate group.

Sorry, I was kind of joking, haha. I def could lose some weight but I'm 6'4".

This just for a fun track day bike. I'm not terribly aggressive, just average intermediate.

As a general rule, most OEM springs are dual rate, to try and accommodate the widest range of riders possible. Linear rate springs are considerably better.... The bike will be much more consistent in bump performance, which makes the damping more consistent, and the steering, etc.

The right springs for your weight and use are one of the best investments you can make, imho. Improved brakes, then suspension, THEN hp and weight mods....

Definitely. I'm just trying to make the best of what I have at the moment.

Look in the owners manual and see if it recommends settings for a passenger. At a minimum I would add some preload to front and rear.

You definitely do not want to just set everything to its stiffest.......

turning in all the preload
turning in all compression and rebound damping
All this will accomplish is an even worse ride comfort wise and even worse handling bike becasue you will skip over the track, pack down the suspension in ripples/wavy conditions and generally just ruin all handling of the bike......

Do the proper suspension measurements
free sag
rider sag

and see where you are at


But even on a budget, if you can do it on your own competently..........

springs and oil vis change is maybe $135 front and changing just the spring in rear another $125
only then would I start worrying about damping rates and adjusting the compression and rebound dampening


You cannot fix a leg amputation bleed with just a small butterfly bandage and that is exactly what you would be trying just "setting everything to just the stiffest"

Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Your OEM springs will be of limited value, due to the loss of travel in the soft part of the dual rate spring. You're heavy enough to cause that part to be completely compressed, so you are actually riding only on the hard part of the springs. You give away near half your potential suspension travel for zero gain.

A single rate spring, equal to the hard part rate, would near double the size of bumps the bike can hit before the chassis gets bounced around. That can only be a plus.

The stock damping may or may not be suited to the part of the OEM spring you're actually using, and there is a very good chance it's even less effective due to aging.

You're chasing 'good enough ' on what sounds like a tight budget. I respect that. Pay someone at the track from a suspension shop to set up what you have..... Should be less than $100, more like $50.

There could be some improvement from this; they could very easily tell you the same things you are heading here. You get what you pay for....

I thought you’re racing for some reason. 300 at 6’4” is still really overweight though unless you’re super jacked lol
