'11 F4 Track Suspension Setup

Can anyone point me in the right direction with regards to fluid levels for the forks as I am thinking mine are too full. I have been riding on the track for a while and under extreme braking (back wheel about to come up) it seems I still have well over an inch of travel left (zip tie method of measuring). I am also wondering if anyone knows where to find the details on both the front and rear spring rates as I have searched and can't seem to find any definitive answers. I would really love to get this thing dialed in.

Thanks in advance!

Presuming your sag is set correctly.....you never want to completely use up all the front travel under hard braking...you may still hit some small bumps and need that last bit to accommodate. I have no good suggestions for your bike, as mine are older models, but I found the factory recommended (from the owner manual) track settings to be pretty spot on for me with minor adjustments to damping.

Have you checked the workshop manual for spring rates? That said, you could try lowering oil level 10 mm and see how it does. Easy enough and reversible if results aren't what you wanted.

I used to be fast....now I just dream about it.

Thanks for the response... I will be pulling them apart tomorrow. The manual had the proper oil info.

Still can't find the spring rates for the front or rear? Any insight on this?

thanks again

The insight is that there will be no record of the current spring rates.

No record? I need the spring rate of the factory springs that came installed from the factory. I am sure there is a record of this somewhere. I just can't find it.

You aren't listening....we've been through this before.

I'll just say you won't find a record and each bike, even within a production run, can have differing spring rates.

Please, prove me wrong!

So let me get this right, when buying springs one just has to blindly pick a spring hoping it's either softer or stiffer than their current springs? ...come on. I guess the info the ohlins rep sent my friend for his Duc 1299 was made up?

Two things: 1. You aren't talking about a Ducati. 2. You aren't talking about Ohlins.

1. Ducati and MV both have forks with both have springs which HAVE SPRING RATES 2. The name of the fork manufacturer doesn't change how they function.

If you don't have something of VALUE to contribute please don't bother responding... I am sure you would also like to tell me that the amount of air in the fork or the weight of the oil or the valving doesn't matter either? or perhaps that only matters with Ohlins suspension... SMH

I think what he is saying is the spring rate isn't published by MV.... Not that is doesn't have a specification, just hard to find. Not listed in the MV manuals.
