Just a quick note those 'tup north considering suspension work, TW Suspension Tech in Preston got my 2015 DL650XT sorted out very nicely. I'm a lot bigger (OK, fatter) than the stock suspension engineers envisioned. Teut fitted Race Tech emulators and a Nitron NTR2 all sprung for my weight. Made a big difference. He's a one man shop and very busy. But good communications, no drama, and a really nice bloke.
