Excellent indepth video explaining sag and what adjustments and changes has an effect on your setup. Spot on!!!

Thanks Terry. Great vid. I got my YZ125’s suspension totally rebuilt by you guys last year as well as my CBR600RR ten years ago. I still remember coming to one of the races at Eastern Creek helping you and Grant one Sunday. Great learning experience

Terry! Been watching your videos in America. Thank you! I have a couple questions: 1 sag is set and you go outside to test, is that the High Speed Compression you are adjusting? If rider likes increase in dampening (clockwise) what do you do to the setting of the sag at the shop? If rider likes decrease in dampening (counter-clockwise) what do you do to the setting of the sag at the shop? Finally, once sag is set where are you going with your high speed dampening? Where are you setting it at since the adjustment has now been compensated on sag.

Great explanation on the relationship between Spring rate and setting sag. I now understand that just dialling up preload on a soft Spring may not be the answer. Looks like a visit to Shock Treatment for my F800GS.

Terry, you continue to deliver more Science with each video, I never factored in chain adjustments affecting the sag, thank you !!

Great video, very complex approach and good explanation. I'm wondering how far from theoretically perfect sag value You went based on rider's feedback but for sure this bike is now on completly different setting. Great job with video.

Amazing info. I have seen a lot of these and this is a masterclass. Going to watch part 3 now - I ride tarmac Supermoto so I'm looking for some insight there as sag figures will be different again 😊 Thanks 👍

Can you please make a video about the front sag (or not) with regards to off-road bikes? The one for road bikes made a lot of sense, but I wish you had a video for off-road bikes as well. Thanks!

Nice. Do the same percentages apply to ADV bikes?

Guys, thanks for the video, it's very useful! But I wanted to deduce the determination for the word sag. is it possible to call a sag a range? Sag as a manufacturer's recommended suspension compression range? A static sag is from 30mm to 40 but its a range, it is a recommended range and for a rider sag also is a recommended range. So is the sag a range first of all?

Do you take measurements with 1/2 tank of fuel to average out the bike's weight?

@shocktreatment5495 4 жыл бұрын

At the 1.38 mark I should have said that there will be "more" Static sag with the lighter rider. Sorry...my mistake. It gets sorted out later in the video.

What was you turning on the track compression or rebound

How are you adjusting sag with a t handle? What is this magic! Please do tell!

@shocktreatment5495 6 ай бұрын

WP and Xtrig have wind up preload adjusters that are activated via an 8mm bolt. These come standard on the Pro shocks@@shaneburesh9173

Do you record the preferred sag setting for future use or do you repeat the process?

@thetruthserum2816 11 ай бұрын

Can you talk about Titanium springs? Progressive springs? Viscosity of damper fluids? Any telemetry used to measure swing arm and fork throw with position sensors + G's sensors to measure what the rider feels subjectively to dial a tune? I notice the Honda race bike has a ton of data ports...

@shocktreatment5495 11 ай бұрын

Yes. I would be happy to go over that. It would make for an interesting video

@chrjamrho 10 ай бұрын

should i assume this is all being done at the factory rebound/compression setting?

@enduro-parts-aus 5 ай бұрын

Do you worry about fork sag to confirm correct preload ?

@zanepuna84 4 жыл бұрын

Great videos. You say you're adjusting the preload each time with the t bar. Does the Husky have a quick adjustment compared to the YZ450F and the 2 x nuts? Or are you adjusting the compression or rebound?

@haydenflinner Жыл бұрын

it's a quick adjust, listen to the squeak of the spring. compression/rebound will just click quietly and won't change sag.

I believe he's using an X-Trig shock adjuster.

Terry, why is front end never checked for sag? Surely this affects the geometry?

@shocktreatment5495 3 жыл бұрын

Front sag will naturally effect geometry but it does not respond well to static measurements/adjustments due to the level of drag/binding in a telescopic fork. I prefer to set the front by a ride and adjust method (dynamic). Its more relative and doesn't mislead.

@romanov9580 2 жыл бұрын

10% of 600 is 60 so why did you put the ideal static setting at 38.5mm? That is only 6.4% static sag compared to free sag. But yet you recommend 10-15%? Trying to wrap my head around 30-35% rider sag of 600mm. That would be 180mm rider sag. And you called his rider sag good at 106.5mm that is 18% of the total free sag.

@shocktreatment5495 2 жыл бұрын

Hi Romanov. Most dirt bikes have appr. 300mm of travel, 10 - 15% is 30 - 45mm......30 - 35% is 90 - 105mm. Any measurement is the garage is not final and ultimately it is what works on the track that counts. We actually had to wind on a bit more preload once we tested to get the best ride quality.

@shocktreatment5495 4 жыл бұрын

They do but if you have additional racking / panniers etc at the rear of the bike, they are prone to influencing the static sag as they are in a position of high leverage. This needs to be considered
