Steve I have 340's which are 20mm over standard, 320's are stock length and I wanted extra clearance and improved steering rake, also I have 35KG springs as I asked for extra heavy duty cos I tow the heavy camper (about 100 lb on draw bar) and I weigh in at about 240lb the wife weighs about 120lb (guessing of course you know women don't like to tell) and then luggage on a trip and they cope excellently, when riding Solo I have nice stiff sporty suspension, I can back them of for a softer ride but hadn't bothered while I had the Darkside but the Brigdy gives a harsher ride so am thinking of having a play with backing of the damping a bit first
