I have owned my 2021 MT-10 for one year and have put on 2,500 miles as of July. My weight is 215 LB's in street cloths. I did not touch my suspension settings for the first 600 miles of break in. The suspension as well as the engine need time and miles to break in and loosen up. After the 600 mile service I started to adjust the forks and shock from the stock settings. With the forks I was 14 turns in on preload from full soft, rebound at 4 clicks out from full in and compression was 18 clicks out from full in. At these settings the forks would only occasionlly bottom, but I could still get them to bottom. With any more preload on the spring I was riding on the linar part of the spring and all of the progressive part of the spring was compressed. The forks at this setting were harsh due to the amount of compression damping I had to install in order to not have them bottom all the time. Definatly a comprimise. The rear shock is much worse for my weight. For the rear shock I had to add 2 3/4 turns of preload which gave me 8mm of sag with no rider, this is the bare minumum of static sag. With me on the bike I had a total of 46mm of sag. The high speed compression was set in the middle, 3 turns. Low speed compression was set at 10, sometimes 8 clicks out and rebound was 4 clicks out. Still the shock would bottom even under hard exceleration. This situation destroyed my stock rear tire in 2,000 miles and the front tire was like new. The rear shock was not right for my weight and the way I ride. Having Ohlins shock and forks on my 2004 Kawasaki ZX10R I desided to just replace the rear shock instead of a revalve and respring as it would cost about $600 with shipping and the piston kit and spring. I started shopping around and got a good deal on buying an Ohlins TTX shock and Ohlins forks as a package. They resprung them for me for my weight 10.5 springs in the forks and 10.5 spring on the shock. The difference is night and day form the stock components. I have put about 600 miles on this suspention and have them pritty much dialed in. Forks have 7 turns of preload, compression is 12 turns out and rebound is 10 turns out. The shock has 7 turns in on the preload adjuster, compression 13 clicks out and rebound 14 clicks out. With these settings I have 34mm total rear sag and 35mm total front sag. All the settings are roughly in the middle of the range, which is where they should be. This my seam extreem, but at my age the MT-10 will probably be the last bike I ever buy. I tend to keep my bikes for many years as you see with the ZX10R that I still have (But may sell soon). I save all the stock components and if I do deside to sell the MT-10 I will just put it back to stock and sell the Ohlins components seperatly. I use to believe in evolution instead of revolution, but with age time goes quickly and I may only ride for the next 10 to 12 years, not 25 anymore. All I can say is if you are 180 LB's or more and ride agressively you may need to upgrade your suspension. One other note, The ohlins forks are much easier to service than the stock forks. You can pull the forks apart and change seals and oil with out having to "Smash" apart the forks like you do with the stock forks. I change the fork oil at least every 6,000 to 8,000 miles and as I have the tools to service the Ohlins forks its much easier than taking the stock forks apart. The shock always has to go back to Ohlins for service but they have a great turn around time especialy in the winter. Just my experiance, Great bike and I do intend on keeping this one.

I ended up just getting springs from K-Tech (front and rear) to suit me (probably around 255 with gear) and between that and messing with suspension settings it made a huge difference. AFAIK the bikes are sprung for a 180-190lb rider from the factory just like most sport bikes are. The only thing I've yet to do is set my sag

What weight springs did you get for your stock shock and forks? Just curious.

With any more preload on the spring I was riding on the linar part of the spring and all of the progressive part of the spring was compressed. The forks at this setting were harsh due to the amount of compression damping I had to install in order to not have them bottom all the time. The stock springs in the standard MT (not the SP) are linear and rated @ 0.93 kg/mm.
I replaced the right hand spring in my 2018 with a 1.0 kg/mm spring from Stoltec in order to obtain the proper static sag and retain sufficient fork travel during track use. Before I did this, I was using nearly all of my preload adjustment with the stock spring (I was barely 1/4 turn out from full in). Dave Moss suggested that I replace just one spring at first to see if we could get it in the desired range and it worked.

That fork spring is linear you can tell by the top windings being smaller than the bottom spring windings.

I ment to say Progressive, Not linear.

I ment to say Progressive, Not linear. It's linear, the taper has no effect on spring rate. Only a different wire gauge can do that. The taper you see on the end is there to assist in centering the springs and reduce spring noise inside the fork tube.
