How To Set Sag On A Dirt Bike

SAGGY
Dear Mr. Know-It-All,
Recommendations on rider shock sag are specified to the millimeter, all the same my rider shock sag varies 5mm or more depending upon where I sit down. Is daze sag measured when all the way upwards on the tank for cornering or all the way back for braking, or somewhere in betwixt where I motion during dispatch depending upon traction?

For me, it seems like setting the shock sag to spec provides just a starting point. Then I cease upwards trivial with fork height and stupor damping to cure the chopper or stinkbug sensations.
Please provide some clarity on stupor-sag recommendations.

For the thousands of stories published on shock sag, there is still a shaker of doubtfulness on the proper process. The WP team'due south general dominion for setting sag is accomplished while continuing on the pegs, manus on confined, with someone holding the auto upright. The helper should push down several times on the rear section of the automobile, trying to get it to settle where the leap and shock damping hold the drop. The measurement is taken from the rear beam or rearward point on the swingarm and should run perpendicular up to the rear fender.

Now there are differing opinions as y'all've stated. Pro Circuit says to set it with the passenger (wearing total clothes) seated forward on the saddle with his feet in forepart of the footpegs.

Precision Concepts says, "Properly setting the sag can make a big divergence in the bike's handling characteristic. Having the sag also low volition make the bike feel squatty and hurt the cornering graphic symbol of the forepart stop. Conversely, a sag that is tall tin can pb to an active stupor that may exist more likely to kicking and a twitchier front. Generally speaking, most modernistic bikes tend to like sag measurements from 100–108mm. We've found that for closed-form conditions (i.e., motocross, Grand Prix) riders typically like to be on the lower finish of that range—105–106mm. In contrast, desert atmospheric condition will sometimes require a slightly taller sag—102-104mm. This can help get a longer travel experience for the faster conditions."

The Race Tech gurus say, "No matter the method, setting the race sag helps determine if you have the right-charge per unit springs. Spring sag is the amount the springs shrink betwixt fully topped out and fully loaded with the rider on board in the riding position."

My final opinion on the discipline is that setting race sag with the rider aboard is crucial to getting the proper leap rate. I run between 102mm and 104mm of sag. I practice mine standing with an associate holding the front of the motorcar. Similar you, my settings mutate with a mere shift of my proportionally audio noggin, then don't panic with slight changes. I e'er utilise a Motool Slacker digital tuner, which makes for accurate readings. I can do it myself with their remote LCD, and this is handy, only yous tin can use any number of measuring tools—from the Race Tech Sag Principal to a record measure. Remember, your riding style that day can have an effect, also as the amount of coffee you consumed in the forenoon. Exist resilient. Test. Make notes, and don't be afraid to make changes.
