Fork pre load adjuster’s

Easy to fit using standard springs and tube spacers , just trimmed it hem down by 5mm as suggested and they work a treat time will tell over longer journeys, when fitting do not over tighten and put some cloth or tissue under socket as not to mark the finish .

Got marked/scraped easily although putting tape around nut.
