Setting Sag

Collin_Palotto
Hey guys, had a question regarding setting sag. I recently had my suspension done by race tech for my 2023 Crf250r, they have a different way of calculating the sag than honda does in the manual. Has anyone else come across this dilemma?

Race tech instructions aren’t bike/chassis specific (at least in my experience) I’d go by your manual and just be consistent measuring the same each time.

I spoke to the tech at race tech and he insisted on setting the sag the way they recommend. just seems strange that they wouldn't take the manufacture's recommendations into account.

You have chosen Race Tech as your suspension tuner and paid them as such, so I would go with what they say.

The only difference I can imagine is Race Tech takes 2 measurements for sag, to account for stiction. This is not necessarily in conflict with the way Honda says to "measure" sag, it's just more accurate.

The other difference might be the actual amount of sag, such as 106mm versus Honda saying 100mm, for example. Again, go with the advice of the tuner you have hired.

The Difference is the the point they take the measurement from, racetech is standard and takes it from the inside of the axle, Honda suggests it be taken from the back of swing arm. However, I will probably end up rolling with what racetech suggests.

How much does the result differ between the two methods?

All you are trying to accomplish with either point is it being a fixed point (along or near the arc of travel) and repeatable. Pick if you like it in the hole or on the arm and continue on that way for the foreseeable future

As others have stated, I would recommend following what race tech recommends. This takes into account the position of the axle, as that does effect sag measurement (further forward vs back can effect weight distribution to the rear of the bike). It may be millimeters, but it all counts!
In my experience, making slight adjustments to sag from track to track can be very beneficial on the Honda as the chassis is very sensitive to set up (previous and current gen). I’m running 104-106mm on my 22’ crf250r depending on terrain (sand vs hard pack).
Good luck, you’ve got a great bike!

The point where you choose to measure is irrelevant. Its the difference that is the required value. Be careful measuring from inside the axle. Make sure your tape "hooks" at the top of the hole each time. Using the rear edge of the swing arm could give easier repeatable point. Irregardless of where you measure, when you take the difference from bike on stand to bike on ground you should get the same number.

Motion Pro Sag tool is really easy to use. Takes all the guess work of where it hooks inside the axle etc. it’s always consistent and static. As long as you mark the fender where you measure at so it’s repeatable your good.
