The reason is bike setting is important is that riders have a certain riding style and behavior on the bike. Poor match = poor results. Again, Roczen and Tomac, and Barcia being prime examples over last 2 years. Name one rider that "mentally has gone from outside top 5, to inside on the same equipment, same settings? Tomac vs Herlings...

I think it is setup related with Hill. Reason why they are trying so many different things during weekend (testing). JS7 does not like to train so he has himself to blame. You make mistakes when you are not in shape. I agree with Matthes, this "It is mental" needs to stop. The top 5--8 riders, that can go quick...

Sorry that is not a fair statement. Could say it is 80% bike and 20% rider. Both need to gel. Barcia success at A1 is 100% bike(+rider)-related.

It is the combo of (bike+rider)+(team+funding+access to parts) I'm my view JGR has only taken on already lost riders, besides Hill, or medioker riders. And then signing up bikes that is least of interest where only a handful riders in the world could make it on. So not fair to say it is teams fault. If they had funding to...

With 46nm shock spring for my 200lbs i could run 104-105mm sag. With the 48nm i could not, armpump directly with AER and CV spring (2017, 4.8, 420ml). But that was with a revalved stiffer rear shock. So gona try now with stock valving, 48nm and 105 sag. What setup in rear you running?

Yea, but kind of the same as with engine mounts, yes changes, but geometri? No. Have little to do with the length of the forks. Wonder why they did the change frame? I ordered a Acerbis skid plate for 2016/2017 models, and it fitted my 2017 SXF.

The guys at WP in Cali did not even know what sag was printed in the manual 2016. They where like question marks when i went there and asked what sag they run on the new 2016. We (WP) run 98 for supercross, and 102 for MX. Really, the manual says 110mm they asked me.

108 sag you probably need 3 line. 105 second line. Depends on static sag/preload (+HSC) compared to your weight. I dont like going under 2nd line, chassi just drags the ground.

First of all, The AER fork is 950mm. 4CS fork is 940mm. Fork stroke is 310mm for AER fork, and 300mm for 4cs fork. So 10mm difference. Why would this be a problem to run 4CS fork on 2017? The 2016 SXF chassi is IDENTICAL and it worked with the shorter 4cs fork. Sure some rider dropped it down and...

There is no chassi difference between 16 SXF and 17. So run them as you did on your 2016. If anything, theoretically, they did go the other direction lowering the front (or raising the rear...) between 16 and 17 since they went from 110 sag to 105. Some minor adjustment on shock was made between 16 and 17 but nothing...

Problem with running in steep stairs or hills is that your legs will give up before you reach maximum heartrate. I would not reach more than 90% of my heart rate doing that kind of exercise. Same as sitting on a exercise bike and putting the resistance to maximum and then try to reach max HR.

Here is one example

When i race MX, it takes me 60sec to go from ~120bpm to 190, then i stabilize at 194-197 for 20-25min depending on moto length. My max is 200bpm. Also depends on which type of track and conditions. Funny thing is, i cant run for more than 3-5min at 180+ before lactic acid puts a stop to it

Agree, it is easier to maintain it and you stress the body less with low intensity. You also has to consider injury and sickness. Screwing up a muscle in your leg can take away several weeks of training. You also easier gets cold if you stress the body heavily. Many that do 6-10 workouts per week, end up with the...

Running to slow then, or to low incline You might have very good cardio fitness. Max HR is at least 175 as you said. So i would do intervals. You can do up to 10, maybe 11mph on treadmill but then it starts to get sketchy and you should instead increase incline to find the right combo to get...

You are not able to run 50min at 90%+, it is almost impossible. It is more likely you are high zone 3 or maybe zone 4. First determine you max HR properly. Motocross is exercised at 90-100% heart rate for 10-30min depending on the length of you race. Heart is a muscle, and it shall be trained to what you...

Here is a max pulse test you can do on treadmill. Warm up, 15min. 5min walking, 5min running at 6mph, 1min at 7mph, 1min at 8mph 30sec at 10moh. Rest 5min. Then 1min at 6, then 1min at 7, and then increase 1mph every 15sec to 10mph, then switch and increase incline with 0.5 every 15sec for 4 times instead...

Cycle and rowing normally provides lower hear rate than running, just because you are sitting down. So no good for determining max pulse.

220 minus age is useless. There is an equal chance you have 190 in max puls which means you ate not at those percent you say. Do a max test by your own at the gym running on treadmill. Easy done
