After extensive 'testing', with multiple bikes, I have to disagree with that.
At cruising speed, the bike is running more revs, this in turn means more fuel - lots more fuel.
Over a couple of thousand miles with the following bikes;
Bike 1: Akrapovics & K&N Filter, 15T sproket
Bike 2: Single can (no Cat) , Kev Fuel Mod & Foam filter, 15T Sproket
Bike 3 : Completely Stock
Bike 4 : DNA Filter, PC-V, Stock cans and 14T
Bike 4 was consistantly using .5 to 1 litre of fuel per full tank over the others. With the DNA filter and PC-V I think it is going to be a little richer, but compared to Bike 2 I think the comaprison should be about the same.
The riding was alot of fast off-road and some open road work.
After looking at what the 14T delivers over the 15T I am now of the opinion that gearing down is totally un-neccasary as the bike is happier at speed over rough ground anyway, and it revs too high when cruising (with a 14T)
I have a 14T that has 2500 miles on it, it will be off the bike today and free to any home that will pay postage - a PM will secure it.
