I have had a look and it seems only Dunlop do a 130 60 19 front tyre for these bikes. I have read that some people are running 120 70 19 as there is more choices. Has anyone on here yet had to replace the front yet.

Probably get shot down here , but at 14000km , I,m really happy with the stock tyres .

I'm about 5000 km away from changing my front D407 stock Dunlop. This will be my 4th. I have no reason to change brands. You may want to check out the Dunlop American Elites.
They are a little cheaper, (no Harley logo), and different tread pattern. The Yanks seem to like them.

I was disappointed that the Pirelli night dragons don't come in this size. I just like to have a choice. I still have a few thousand left in mine so not urgent yet.

thanks Paul, I did check out the US forum and that's where I read about people using the 120 70 19.
