Recommend fork spring rate

Bodoe » Wed Apr 20, 2011 7:13 am

Hi forum members,

I experience my front fork springs are to soft in my MC21 SP. After track days I can see that the forks have been fully compressed. The springs measure to 295mm length which is just at the service limit.

My weight is just under 90 kg including gear and the bike is ~10 kg lighter than stock.

I have tried to find the spring rate for the original springs, but without luck. Has enyone measured the spring rate of the original springs for a MC21 SP bike?

If I were about to replace my springs, has anyone themselves changed springs and what was your spring rate? What was your total weight that was used for calculating the spring rate?

The spring rates I can choose between are 10 N/mm, 9,5 N/mm and 9 N/mm.

Appreciate any help in the matter.
