Dear friends. I am always keen to improve my riding style and reduce risk.
I have learned much from reading commentary on this site and riding with and talking to site members
I saw this youtube video courtesy of RoadcraftNottingham.
It's not about riding Harleys, but riding motorbikes in general. It goes for about 16 mins but makes good sense so give yourself some time to view it.

He is quite cautious but he would be a pain in the ass to follow, "Oh, he`s gona overtake, er nope he changed his mind hes gona turn left,,, Dow! hes gona overtake again"
What is he talking about if you want to go for your "advanced", do they have different licences over there?
+1 some good tips there
Haven't watched it but based on Binnsey's comments I agree with him on the position on the road. I would never ride in the "sump line" - generally the RH wheel track, moving slightly to the centre of the road if coming up behind a car so that you are visible in both car mirrors (Side and central), have a clear view ahead and in the event of a sudden brake by the car - you are not going to plough straight into the back of them.
No science or education to my view - just my seat of the pants view of the world.

I'd think a full grip just adds the levers to stability control - it should make no difference at all - unlike a two finger stop which means fingers can be in the way and the force of your grip becomes flimsy. Trained, professional racers spend shitload of cash on their brakes and clutches so they are setup to perfection for them while the guys at stay uprite (presuming its a riding course) deal with everyday people, with everyday bikes, under everyday conditions. I'd be more interested to know how professional bike racers cover their clutch/brake on their everyday bike and why.
Right or wrong, I use the two finger method Oneball describes, although only on the brake. Sometimes out on a country road I'll leave all fingers off the lever, but mostly around the suburbs and local roads, I leave two fingers on the brake. I think my Dad might have told me to do it many many years ago, theory being that if needed, I'm squeezing the brake more quickly than if I have to get my fingers off the grip and on the lever.
Just noticed my avatar on the left, looks like I sometimes only have one finger on there too!!
When talking about the sump line, there is usually a lot less crap on the road where the cars can just drive along, compared to at intersections where the traffic stops and any oil or coolant can drop onto the road.
and remember "SWIFT" Start Wide Intend to Finish Tight.
