I'm wondering if it will work for me - I'm 64kg. Should I stop going to boot camp and start eating more pies?

Are you related to Danny Pedrosa?

For all the riders that are a bit heavier I have found a chart used by Fray Bentos Racing for increasing compression strength depending on what you have eaten, hope it helps.

I fancy this MCT soft spring setup too but before I book anything and travel 400 miles does anyone know of any suspension firms closer to the border. I'm in central Scotland.
Cheers

Simon, there is a tuning place inside Knockhill, directly opposite the reception. I've been told he's great with suspension, worth a try being so close.

it's Eddie at ERS , he's the man for suspension he set up my bros rsv4 and transformed it. he's a bit bonkers though......
 
Re: MCT Suspension

Roadrunner, do you mind me asking what weight of spring you ordered? I've just done the same spring swap as you but fear I should have ordered a softer front spring. I ordered 9.5Nm for the front and 85 for the rear. The rear feels great but not convinced about the front.

thanks!

With 85 rear and 9.5Nm front I think you are running with the HP4 set up, for a rider of 75kg all kitted up. I too went with the 9.5Nm front springs but the 90 rear as firstly, I didn't have much of an issue with the rear, and secondly, Alpha Racing, my supplier, didn't offer an 85. After lots of emails to Alpha Racing, I was advised that..... "the stock suspension springs were too hard for me",which I already knew, "and that 9.5 or 10.00Nm front and 90 rear would be a very good solution for me" so I took the plunge, and went for the softest they had, as this suspension issue was really spoiling my enjoyment of what is a great bike.

Obviously, it's early days, but first impressions are that the suspension set up is a vast improvement on what it was, namely that the cable tie wrapped around my fork leg is now hovering about 10-15 mm from the the alloy bottom housing of the fork....and not inches as it was before! BUT I now have the option of softening or hardening the pre-load to fine tune that travel. Plus I shall now be able to play with the damping adjustments, as because the suspension was so unforgiving previously, I had to set front and rear damping on -7 all round. So time will tell.

I hope this is of help 95inches
 
I'm 87kg before I gear up. My road biased Ohlins/Bitubo are 9.5 Front and 9 Rear. Makes for a pretty plush ride.

Though I think I may have to fit a 10.5 in one fork to give me more support for track work. Taking my spares to Almeria.

MCT confirmed I can use combinations of spring weights to find the right setup. Its not perfect but with 2x9.5's and 2x10.5's on me I can test out 9.5/10/10.5 setups by changing one spring at a time.

Spring Weights

Using different spring weights in each fork leg is fairly common practice to fine tune setup. It's just whether or not you have the time between sessions to change them. Just make sure that you keep compression and rebound figures as a constant so that you can understand which spring weight combination works for you.

Yes Ryan, as I know, that you know, that dear old BMW do just that with the 2015 Gen 3 by fitting a 9.5nm spring to the left DDC leg and a much heavier 11nm to the non DDC right leg.

They do? Would that explain right turn assist, Is it a shorter but stronger spring?

Spring Weight

BMW's heavy OEM spring weight combination is exactly why I originally had issues with generating feedback with the DDC suspension. Changing to far more suitable springs, along with some internal changes, solved the problems I was having. I now no longer feel the need to purchase an aftermarket cartridge kit and rear shock.
 
Spring Weight

It will have nothing to do with the veering issue that some owners experience. Using differing spring weights is most likely just BMW's way of setting the suspension to suit an average market demographic.

Thanks Roadrunnner very helpful. It sounds like we are in the same 70-80kg bracket, interested to hear you have the 90 rear spring. I am getting 20mm rider sag on the rear and 11mm front without adding any preload.

you can get an 8.0 Nm front spring and an 80Nm rear but that is probably too soft. I am going to reduce the oil level and see if that helps first as my zip tie is barely halfway down on the front!
 
Fork Travel

A zip-tie around the fork leg is definitely a useful indicator for monitoring fork travel and if you are bottoming out. If it's not moving that far it may also mean that you could be braking a lot harder than you currently are especially on track.
 
Looking at the US forum it seems Wilbers helped develop the DDC system.The sell the relevant springs for ?134 a pair ranging from 8.0 to 11 in 0.5 increments. The right fork spring can be changed without specialist tools as there is no preload spacer.
