My old M750 was 3 years old when i got it in 2003 and the previous owner had added a lot of goodies ,,, now 19 years old Im giving her a major refresh after my daughters accident last year ,,

had the forks apart and I was told they has Ohlins 8.5nm springs in with 5w oil ... but what came out was progressive springs probably hyperpro

now the bike has always handled impeccably and been comfy and controllable with the standard showa forks but Im curious what is the Progressive Spring rate ???

so today went down to faulkner springs who have a very expensive spring test bed for Mclaren cars who the make the suspension and they tested my fork spring ,, seems it starts out at 6.5nm and steadilty goes up by 7.5nm at 25mm to 8.5 at 50mm and 9 nm at 75mm interesting

so now I know ....
