I dont know if it has been covered, but I am not reading 23 pages. Are all the cameras front facing? I am getting the train to inverness to pick up a motorbike to ride home, can the cameras catch a bike?

Rear facing, so yes they can catch you. But, for the 60 zone you can sit at 68 without being in danger of a ticket. The Inverness to Perth sections of dual carriageway are not covered by the ASC's so watch for cops and mobile cameras.

What JS Hell said. I stick the cruise to 68mph speedo (65mph GPS) on the 60s, and up it to 80mph in the Dual carriageway sections. Being doing that for as long as the cameras have been up and never had any points.

Nailing it down the A9 on a motorbike in October aint gonna be too much fun anyway. Handy for a overtaking a few cars/lorries, but hammering along at 100+ on a relatively straight bit of road is not exciting to me.

Thermals on and sensible speeds, enjoy the scenery!!!

Its a single cylinder w reg f650gs so I suspect 100+ is asking a bit much anyway, but I would like to make better progresstban I do in my van, fking hate that road now, i knock back jobs up that way now.
I hope the heated grips still work.

I have always been under the impression they are front facing only, other then apparently one that also has rear up near Moy (quite how it works if only one is rear facing I don't know...............)

I used to do the A9 a fair bit on my bike, and while I don't ride at silly speeds, I didn't bother with the limit much and must have been over the average occasionally.

As above though, setting cruise at the speeds mentioned above on bike or car has been fine.

If you are travelling at busy times you are unlikely to exceed the average anyway these days whether you pay attention to the limit or not

I try to work it out in my head as I go along.

Stuck behind a truck doing 50 for a few miles? Then when you get a clear run you can go a bit quicker - it usually translates into being able to go faster on the DC sections and overtake a few more trucks/campervans, etc.

Obviously it helps that there are reasonable distances between each set of cameras.

The dual-carriageway sections aren't covered by the cameras anyway. And each section of single-carriageway is independent of all the other sections AFAIK, so you're starting from scratch at each section.

I share the same views - also love maintaining speed after the DC sections until I get to the first camera - I think it's half a mile before and after each DC section.

Usually works, but the cameras are really not that far apart - it is quite easy to get caught out if the road is quieter than normal and your back of an envelope maths is competing with Heartland or Radio Scotland which is about all I can get in my car for a good chunk of the road

You can make up time on the sections before and after the DC before the first set of cameras appears - you can usually tell the "regulars" as they tend to apply DC limits to those parts, and some are longer than others.

The appearance of trafpol or camera vans randomly on DC sections when you least expect them (early morning, late in evening) I have still had several close shaves with.

I didn't know that, thought it was a sort of overall average for the route plus the individual sections.
Anyway cruising up the long DC section at Slochd at an, er, enhanced pace doesn't appear to have resulted in any unpleasant correspondence

I was up there in the summer, the Amigo app displays your average speed so you know when it’s safe(r) to give it a tickle.

Note the AFAIK bit! For all I know they do stitch the various sections together, and I've just been lucky (although a quick calculation implies that if you do a lengthy stretch at 50 you really have to press on to get your average back up to 60).
