Thanks! This is what I was looking for. Quick question: in this video for sag settings he mentions some numbers which probably depend on the bike and rider's weight. How can I come up with reasonable numbers for my bike and weight?
More generally speaking, are there shops that can help me to tune my suspension? Maybe the dealer? Or most people do it themselves?
Most people would say around 25%-33% of the travel which is approx 30-40mm front and rear rider sag for a road bike(including the Thruxton) but there's no hard and fast figure.
It should be the same for riders of any weight that's why you adjust the preload. If you can't get it in the ball Park with the preload then you need harder or softer springs.
Once the sag is set and the bike is not sat too high or low in the travel at either end you could play about with the damping settings using the book settings as a guide. I tend to adjust mine to cope with bumps and in the braking area as it's our bumpy roads that slow me down more than any corners, most people including myself are so far below the cornering limits of a modern bike that a few clicks here or there won't make any difference.
It's nothing you can't do yourself, it costs nothing to adjust it and go for a ride but there is plenty of people who will gladly take your money, some are better than others, that's the tricky part.
I would definitely not recommend a dealer.
