Belated welcome.
Just to add to the 404 speed discussion, in my opinion anyone who drive one at 60mph needs a medal and a hearing test. When I had more road biased tyres on mine the best I got to was 50 but it was only a short burst as the shear volume of everything mechanical was begging me to slow down.
You are right Brian, any hint of a slope sees the speed falling away almost as quickly as when you brake. You can tick 404 off your list at Lincomb next month.
