Handlebars, caps, spacer, washer & springs out. Pushed forks up to check oil level (had to add a few drops), lower forks, put in new springs, carefully place in washer, spacers (new springs were 15mm longer than factory, so re-used factory spacers), screw caps back on, re-attach handlebars, done. 20 minutes tops.
See above. Way easier than I thought.
I used these ones (
Firefox Racing | Triumph ROCKET III – TOURING 2008-2012 Progressive Fork Springs), turned up in 5 days from the UK. Impressive delivery service. I'm still waiting on stuff from ebay Germany ordered same day.
