K-tech 10N HPFS fork springs


K-tech 10N HPFS fork springs are made from high grade chrome silicone wire, heat treated and polished, which is all very nice. But more importantl­y, now the rating is correct for the bike and me. It was fitted with 9N/ mm fork springs – too light for even whippet Superstock racers, and which probably goes some way to explaining why the previous bloke had ALL the adjusters wound ALL the way in.

He also bought the bike with the kids’ springs fitted and probably tried to firm-up the forks just by turning everything up full instead of questionin­g the spring rate. It must have handled so badly. All for want of £85 spent.
