Title: Allround Fork springs
Post by: YSS on December 03, 2008, 07:51:25 pm: Due to constant pressure , I have now decided to construct and make a run of chrome silicon forksprings for all 34 mm forks. OD 26 mm and freelenght 480 mm. That would also cater to take the PD Forkvalve.
The rate I consider to make is 4.5N / mm ,I hope that would even cater for the NSW tracks . Any thoughts , anyone interested. ???

Do you make any fork springs to suit a Honda CR125M? My manual doesn't have any specs for the wear limit on the springs - they are 509mm & 510mm respectively, so I'm not sure if they're past their use by date.

Regards, Ron

I have both straight and offset axle XT forks here and a day off on Friday so I'll check both and let you know.
Both XT and TT use 36mm forks but the smaller OD springs will fit

I think that rate will be fine for an XT/TT,

Brent

I'm interested! 4.5N/mm - suitable for a semi-fat, semi-slow bloke like me?

Discount for bulk buy? ;)
